1.1.1.3 Climatic system
The climatic system controls the inside temperature of the cabinet. Low noise ornormal operation is available. It is located in the top compartment of the cabinet.
The climatic system can either consist of:two Air Cooling Units: ACUs,
or a Direct Ambient Cooling System: DACS or DACS “LN” (Low Noise).
With ACUs
Figure 1--1 shows the S8000 Outdoor with an ACU climatic system.
The topandmain compartments communicate through main compartment air inletsand main compartment air outlets (see Figure 1--2 ). The top compartment has
openings on the cabinet front panel that allow air to enter the cooling units andopenings on the rear of the cabinet that allow the cooling units to fan air out of thecabinet.
EachACU includesa compressor (ac--powered), an evaporator, condenser coilsandrefrigerant lines, external and internal air blowers, 1000W heater (resistance plateheater), digital controller, internal and ambient air temperature sensors, air filters,EMI filters, ac/dc rectifier/alarm board and circuit breakers.
The internal temperature sensors are used to regulate the temperature inside thecabinet. Theyare located on the climatic units, at the opening that enables air to pass
from the main compartment to the top compartment. The ambient air temperaturesensorsenable thePCUto cut itsdc power supply when the thresholds areexceeded.These sensors are located above the BCF or CBCF compartment or below therectifiers.
The external air blower is used to circulate the outside air across a condenser toextract heat from the refrigerant and expel heat to the outside air. The internal airblower circulates air through the BTS and over an evaporator to collect heat fromthe electronics.
There are six LEDs on the front side of each cooling unit. These LEDs indicate thealarms detected on the following type of failure (see Figure 1--3 ):

On each cooling unit there is also a controller display (red 7--segment display) thatindicates the internal air temperature. This controller display has two LEDs :
COOL/DELAY (red): lit when the internal air temperature reaches 40 °C(104°F).
HEAT (red): lit when the heater is on.
Technical characteristics
The ventilated air flow rate is 400 m 3 /hour (14.125 cubic feet/hour).
The maximum temperature of output air is +70 °C (158°F).
With DACS
Figure 1--4 and Figure 1--5 show the S8000 Outdoor with an DACS climaticsystem.
The operating principle is the following:
An air damper opens to admit external air (incoming air being filtered) andcontrols theinner cabinetenvironment bymixingappropriate amounts of outsideand recirculated air.
Twin blowers drive air down the rear duct and into the equipment enclosure viaslots at the rear. Returned air to the cooling system is routed through two sets of
holes in the base, with excess air being rejected from vents either located oneither side of the system (see Figure 1--6 ).
The internal temperature control is achieved by a high quality thermistor having anaccuracy of ±0.2°C (32,36 _ F) between 0 °C (32_ F) and 70°C (158_ F).This deviceis located in the left hand exit duct above a hole on the duct side; the hole ensuresthat the thermistor is constantly in a moving air stream, regardless of damperposition. The operational mode of the Cooling system is solely dictated by theinformation provided by the thermistor.
There are four operational modes:
Low temperature --40 °C (--56°F) < Tcab < 15 °C (59°F)The heater is powered on, the damper is closed to the outside and air isrecirculated via the holes in the base of the cooling system.
Medium temperature 15 °C (59°C) < Tcab < 40 °C (104°F)The heater is switched off, the damper remains closed and further heating of theequipment enclosure is achieved solely by the internal equipment loading.

Normal temperature Tcab = 40 °C (104°F)The damper position is controlled automatically by the modulating motor,mixing appropriate amounts of recirculated and external air to maintain aconstant temperature. Excess air is rejected from the cooling system from ventsat either side of the cooling system.
High temperature Tcab > 40 °C (104°F) Although the damper is fully open, the cooling system is unable to keep thecabinet temperature to 40 °C (104°F) which now rises in sympathy with theexternal temperature. At an outside temperature of 50 °C (122°F), the internalcabinet will rise to a nominal 60 °C (140°F) under fully loaded conditions.
The cooling system is supplied: with two hard alarm outputs:
• The first alarm output signals a fault on the cooling system
• The second one indicates a maintenance requirement for the filter
and with three alarm LEDs for on--site fault diagnostics:
• The red LED indicates a critical alarm for fan failure
• The yellow LED indicates a critical alarm for heater circuit failure
• The green LED indicates a maintenance alarm for clogged filter
On the top of the cooling system, there is a window in the lid which allows theuser to view the LEDs (see Figure 1--5 ). The LEDs are normally lit whenhealthy and off on alarm.
The cooling system is DC powered that allows internal or external battery back--up.The dc power consumption of the cooling system is 400--450 W. The cold start--upperformance of the unit is controlled by an built--in ac to dcconverter (for operationof the fans) and by a 2.5 kW heating element.
With “LN” (Low Noise) DACS
Figure 1--7 shows the S8000 Outdoor with an “LN” DACS climatic system.
The operating principle is the following:
The air damper opens to admit external air (incoming air being filtered) andcontrols theinner cabinetenvironment bymixingappropriate amounts of outsideand recirculated air.
The twin blowers drive air down the rear duct and into the equipment enclosurevia slots at the rear. Returned air to the cooling system is routed through two setsof holes in the base, with excess air being rejected from vents located on eitherside of the system (see Figure 1--6 ).

With “LN” DACS two operating modes of the twin blowers are available:
Full speed mode
Control speed mode
In this mode:
• if the temperature is > 45°C (113°F), the blowers run at full speed (2500 rpm)
• if the temperature is ≤ 45°C (113°F), the blowers run at slow speed(1800 rpm)
The full speed mode or control speed mode is selected by switches located on thecontrol board (see Figure 1--8 ).
The temperature control is achieved by two high quality thermistors that have anaccuracy of ±0.2°C (32,36 _ F) between 0 °C (32_ F) and 70°C (158_ F):
One is located in the left hand exit duct above a hole on the duct side. This holeensures that the thermistor is constantly in a moving air stream, regardless of thedamper position.
The other one is located behind the air inlet, and measures the ambient airtemperature.
Theoperational mode of the cooling system is determined solely by theinformationprovided by the thermistor.

There are four operational modes:
Low temperature --40 °C (--56°F) < Tcab < 15 °C (59°F)The heater is powered on, the damper is closed to the outside and air isrecirculated via the holes in the base of the cooling system.
Medium temperature 15 °C (59°C) < Tcab < TsThe heater is switched off, the damper remains closed and further heating of theequipment enclosure is achieved solely by the internal equipment loading.
Normal temperature Tcab = TsThe damper position is controlled automatically by the modulating motor,mixing appropriate amounts of recirculated and external air to maintain a
constant temperature. Excess air is rejected from the cooling system from ventseither side of the cooling system.
High temperature Tcab > Ts Although the damper is fully open, the cooling system is unable to keep thecabinet temperature to Ts which now rises with the external temperature. At anoutside temperature of 50 °C (122°F), the internal cabinet will rise to a nominal60°C (140°F) under fully loaded conditions.
The cooling system is monitored by:
two hard alarm outputs:
• The first alarm output signals a fault on the cooling system• The second one indicates a maintenance requirement for the filter
three alarm LEDs for on--site fault diagnostics:
• The red LED indicates a critical alarm for fan failure
• The yellow LED indicates a critical alarm for heater circuit failure
• The green LED indicates a maintenance alarm for clogged filter
On the top of the cooling system, there is a window in the lid which allows toview the LEDs (see Figure 1--5 ). They are normally on when healthy and off on
alarm.The cooling system is DC powered that allows internal or external battery back--up.The dc power consumption of the cooling system is 400--450W. The cold start--upperformance of the unit is controlled by an built--in acto dcconverter (for operationof the fans) and by a 2.5 kW heating element.

Autonomy of the internal battery
The internal battery is located in the lower compartment (see Figure 1--12 ). Thebattery backup time is two hours minimum.
Battery voltage thresholds and associated switches
When the battery is discharging (no AC mains), we reach a first threshold level, where part of the load is disconnected. If the battery continues to discharge, whenthe second threshold is reached, all remaining loads are switched off. The fourswitches (one per output) are semi conductors one, VMOS or bipolar.
The backup time is a calculated value dedicated only to the batteries and is given
with the accuracy of +/-- 15 minutes. The value is for a backup of the entire BTSand therefore correspondsto the first threshold. If the mains fails, the BTS isbackedup until the battery voltage is below 45 V dc. After this time, the PCU cuts off thesupply to the DRX or e--DRX or DRX--ND3, PA (or ePA or HePA) and the otherunits are powered until the battery voltage drops below 42 V dc.
1.1.3.2 Climatic system
The Compact Direct Ambient Cooling System (CDACS) controls the insidetemperature of the cabinet. Low noise or normal operation is available. It providescirculating air flowinsidethecabinet through forced ventilation. TheCDACScools
efficiently usingtwofans anda damper system to leverageair temperaturevariancesboth inside and outside the cabinet. It maintains an operating range of + 5 _ C(41 _ F)to+50 _ C (122_ F) inside the cabinet. If the inside temperature is below 5 _ C(41 _ F)at the time of start--up, the heaters switch on and when the temperature reaches 5 _ C(41_ F), the BTS starts up.
The CDACS is composed of two fans, one damper, one heater, one air filter and onecontroller. During normal operations, and when the internal temperature is above0_ C, both dc and ac power are connected to the direct ambient environmentalcontrol system. When the internal air temperature of the BTS cabinet is below 0 _ C(32_ F) only the ac power is available by the CDACS. The fans are equipped with
their own ac/dc rectifier, which means that the system can even in this case operateat full specified performance. in case of ac failure, only the heating function isensured. The internal temperature of the CDACS cabinet cannot be smaller than theambient temperature.
The fans can automatically switch from the ac/dc converter to the S8002 dc systemsupply.
All components are easily accessible and can be changed on site. The dc powerconsumption of the CDACS is smaller than 360W. The cold start--up performanceof the unit is controlled by a built--in ac to dc converter (for operation of the fan)and by a 1.25 KW heating element.

1.1.5.2 Climatic system
The operating principle is the following:
When fully closed, the damper excludes outside air, and air is circulated withinthe BTS cabinet.
When fully open, there is practically no recirculationwithin theBTScabinet.So,the LNS--DACS operates in ambient air that is routed through an electronicequipment installed in the cabinet and ejected via the ducts located on the sides of the LNS--DACS.
At intermediate positions, the damper is adjusted automatically to give a mix of
recirculated and external air to achieve a nominal internal operating temperatureof +25_ C (+77_ F). In a specific country, an optional setting could be used toachieve a nominal internal operating temperature of +35 _ C (+95 _ F).
For low external ambient air temperatures, the internal cabinet air temperature ismaintained above +5 _ C (+41 _ F).
With the LNS--DACS two operating modes are available:
full speed mode (optional)
control speed mode
In this mode:• if the temperature is > 35°C (95°F), the blowers run at full speed (1800 rpm)
• if the temperature is ≤ 35°C (95°F), the blowers run at slow speed
The full speed mode or control speed mode is selected by switches located on thecontrol board.
The temperature control is achieved by two high quality thermistors that have anaccuracy of ±0.2°C (32,36 _ F) between 0 °C (32_ F) and 70°C (158_ F):
One is located insidea hole on the left--hand side panel. This hole ensures that thethermistor is constantly in a movingair stream, regardless of the damper position
The other one is located inside the air inlet duct, and measures the ambient airtemperature
Cooling system operational mode is determined solely by the information providedby the thermistor.
The nominal internal operating temperature (Ts) is set by switches (see Table 1--1 )located on the control board.
The factory presetting temperature is 35 °C (95_ F).

There are four operational modes:Low temperature --40 °C (--56°F) < Tcab < 10 °C (50°F)The heater is powered on, the damper is closed to the outside and air isrecirculated via the holes in the base of the cooling system.Medium temperature 10 °C (50°C) <Tcab < TsThe heater is switched off, the damper remains closed and further heating of theequipment enclosure is achieved solely by the internal equipment loading.Normal temperature Tcab = TsThe damper position is controlled automatically by the modulating motor,mixing appropriate amounts of recirculated and external air to maintain aconstant temperature. Excess air is rejected from the cooling system from ventsat either side of the cooling system.High temperature Tcab > Ts Although the damper is fully open, the cooling system is unable to keep thecabinet temperature to Ts which now rises with the external temperature. At anoutside temperature of 45 °C (113°F), the internal cabinet will rise to a nominal55°C (131°F) under fully loaded conditions.
The cooling system is monitored by:two hard alarm outputs:• The first alarm output signals a fault on the cooling system• The second one indicates a maintenance requirement for the filterthree alarm LEDs for on--site fault diagnostics:• The red LED indicates a critical alarm for fan failure• The yellow LED indicates a critical alarm for heater circuit failure• The green LED indicates a maintenance alarm for clogged filterThe LEDs are located on the front of the cooling system.

The cooling system is required to operate at full specified performance, from a dcsupply ranging from --40.5 V to --60 V (typically --54.5 V) and from an ac supply(typically 230 V +/-- 10%).
During normal operation, and when the internal air temperature of the BTS is above0°C (32°F), both dc and ac powers are connected to the cooling system.
Whenthe internalair temperature of the BTS isbelow 0 °C(32°F), only the acpoweris available to the LNS--DACS. Under these conditions, the LNS--DACS uses itsown internal ac/dc rectifiers to operate at full specified performance.
The maximum dc power consumption is 360 W.
The maximum current required to operate at full specified performance for the dcpowered circuit, shall not exceed 4 A.
The maximum current required to operate at full specified performance for the acpowered circuit, shall not exceed 10 A.
The heater element is used to maintain the BTS cabinet above +10 °C (50°F). It islocated in a fan outlet duct. It has a rating of 1.25 kWat the nominal input of230 Vacand is equipped with stainless steel fins, to maximize heat transfer. The element isturned off at +10 °C (50°F), for rising temperature, and energized at +5 °C (41°F)for failing temperature.
The heater element is protected against over--heating, which can be caused by airfailure or blockage within the BTS cabinet, by a manual reset thermostat located ona top of the fan discharge duct and over the element. It is programmed to set off analarm at 106.5 °C (223.7°F).
1.1.5.3 Filter
The filter located inside the BTS cabinet is monitored by the filter clog switch. Thisfunctions by operating a micro--switch in response to movements of a large areadiaphragm induced by pressuredifferences on eitherside of it. It is factory--adjustedto provide a contact closure to the control board when the pressure drop exceeds 50Pascals.

Back panel
TheBCFback panel connects theswitching part of theBTS. It providesconnectionsfor the BCF boards (see Figure 1--22 ). It receives the external PCMsfrom the BSC(Abis interface) and the six private PCMsfrom the BTS. It alsodistributes the O&Mbus, its own alarms and the 48 V power supply of the ALCO board.
The BCF back panel has the following connectors:
A 37--pin female connector receives the six PCMs of the Abis interface.
Three 25--pin female connectors distribute the O&M bus.
Three 25--pin female connectors each distribute two private PCMs.
A 3--pin connector is used for power supply. A 4--pin connector distributes converter alarms to the ALCO unit.
Thirty 96--pin male connectors connect the P1 and P2 connectors of thefollowing units: PCMI, DSC, PSU, CSWM, GTW, and SYNC.
Thirteen 8--pin male connectors supply the units connected to the back--panel.
The BCF back panel also connects PCM termination resistors in order to reduceradio electric transmission and prevent end--of--line multiple reflection problems.
The P2 connectors are equipped with a localizing device that prevents the insertion
of a board into the wrong slot. This is done by means of cells on the back--panel thatare blocked and tabs that are cut out on the board connectors (see Figure 1--23 ).
The BCF back panel has only one ground. No distinction is made between logicalground and physical ground. For units that use this distinction, the mechanicalground is connected to the logical ground.
However, the reference 0 V of the --48 V power supply (M0 V) is not connected tothe back--panel ground.
The --48 V dc power is protected by fuses.

The C--PA--ICO module provides the dc distribution for the PA and the F--typeconverters.
The MAIN--ICO is a passive board, containing only connectors, fuses and resistors.It performs the digital interconnection between:
the two DRX or e--DRX or DRX--ND3
the two PAs
the CBCF
the RECAL
the duplexer
It provides the power supply for the DRX or e--DRX or DRX--ND3 (--48 V) and theduplexer (+/-- 15 V).
The S8002 standard configuration is O2.
The POWER--ICO module distributes the dc for the CBCF, the USER rack and theRECAL.

1.3.2.1 Radio cabling
The cabling of the BTS components varies depending on the site configuration andthe coupling system used.
The site configurations are identified using the following conventions:
“Ox” is a single--cell site (omnidirectional antennas) with x DRX or e--DRX orDRX--ND3 in the site.
“Sxy”is a two--cell site with x DRXor e--DRXor DRX--ND3in thefirst cell and y
DRX or e--DRX or DRX--ND3 in the second cell.
“Sxyz” is a three--cell site with x DRXs in the first cell, y DRX or e--DRX or
DRX--ND3 in the second cell, and z DRX or e--DRX or DRX--ND3 in the thirdcell.
Figure 1--47 to Figure 1--75 present thecabling systemfor various configurationsand coupling systems.

1.4 Power supply
1.4.1 S8000 Outdoor/S8006 BTS
The power system supplies 48 V dc power to the units in the cabinet from the mainspower supply.
1.4.1.1 Description
The power system has the following configurations:
for the S8000 Outdoor BTS:
• an ac mains box, a Power Controller Unit (PCU), a set of 600 W or 680 Wrectifier units (SRU) and a set of batteries
• anacmains box, a Controller Module, a set of 500W Rectifiers, a DistributionModule and a set of batteries
• an ac box / GIPS and a GIPS module (GSM Integrated Power System)
for the S8006 BTS:
• anacbox, a Power Controller Unit (PCU), a set of 600 W rectifier units (SRU)and a set of batteries
PCU description
The controller module and distribution module make up the PCU.
The PCU connects the rectifiers to the cabinet units and to the batteries (only forS8000 Outdoor BTS).
In this section, the SRU refers to both types of rectifier sets.
The PCU can be connected to a set of several rectifiers whose outputs are connectedin parallel:
for S8000 Outdoor BTS:
• either a set of two to six 600 W rectifiers (one for redundancy)
• or a set of two to seven 500 W rectifiers (one for redundancy)
for S8006 BTS:
• a set of two to five 600 W rectifiers (one for redundancy)
Only for the S8000 Outdoor BTS, the PCU is connected to the batteries locatedeither inside or outside the cabinet. It has four separate outputs (outputs 1 to 4) thatsupply the cabinet utilizations.
There are two types of battery units:

internal batteries mounted on the top of the cabinet, which consist of four12 V dc batteries in series (one string)external batteries located in the external battery cabinet, and configured in amaximum of four strings. Each string consists of four 12V dc batteries in series;the four strings being connected in parallel.
PCU functions
Two types of PCUs are available, depending on the converter type. These two PCUtypes have the same functions but are tied to their own rectifiers.
The PCU has the following functions:
It connects the SRU to the batteries (only for the S8000 Outdoor BTS). Whentherectifiers are no longer running, the batteries can supply the PCU outputsaccording to the option chosen, the choice being by front panel wiring:
• option 1: two of the four PCU outputs are supplied
• option 2: the four PCU outputs are powered (this is mandatory in the case of external batteries
It generates four 54V dc outputs (outputs 1 to 4) for supply of the cabinet boards.
It receives the alarms from the rectifiers.
It receives an analog signal from the temperature probe located on the batteries(internal or external) and sends a signal to the SRU to adjust rectifier outputvoltage inversely to battery temperature (floating voltage).
It generates a disconnection of its four load outputs depending on the signalreceived from two ambient temperature probes (one is located at the top of thecabinet, the other at the bottom).
PCU connections with the SRU
The SRUs, connected in parallel, are connected to the PCU by means of thefollowing inputs/outputs:
54 V (+) and 54 V(--)dc fault (alarm)
ac fault (alarm)
overtemperature (alarm)
missing module (alarm)
floating voltage control
remote control
load share

PCU connections with the batteries (only for the S8000 Outdoor BTS)
The batteries are connected to the PCU by means of the following inputs/outputs:
54 V (--) internal batteries
54 V (--) external batteries
54 V (+) internal and external batteries
(+) and (--) of the temperature probe of the internal batteries
(+) and (--) of the temperature probe of the external batteries
Interface between the PCU and the ALCO or RECAL board
The following signals are the interface between the PCU and the ALCO or RECAL board:
Load1 threshold (PCU internal alarm, also sent to ALCO or RECAL)
PCU protective devices (PCU internal alarm, also sent to ALCO or RECAL)
battery on discharge (alarm) available only for the S8000 Outdoor BTS
dc fault (alarm)
ac fault (alarm)
overtemperature (alarm).
The following signal carries out the control:CEATS 1 (Cabinet Extreme Ambient Temperature Signal).
The following cables are not connected:
Load2 threshold (PCU internal alarm, also sent to ALCO or RECAL)
missing module (alarm)
remote control (used to cut the 48 V dc and switch to batteries)
common alarms.
Battery operation of boards in the cabinet (only for the S8000 Outdoor BTS)
The PCU enables the cabinet to run on either internal or external batteries(connection of the internal or external batteries is carried out manually, and it is notpossible to connect both types simultaneously). Two operating options arepossible.
option 1:• When the internal or external batteries are connected to the system, the SRU
powers all the outputs and, if necessary, supplies power to the batteries(charging phase).
• If the SRU is not supplying any power, the internal or external batteriesenergize output 4 (BCF, user equipment and ALCO or RECAL board).

Copyright © 1999--2005 Nortel Networks
option 2:• When the external batteries areconnected (in which case the internal batteries
are disconnected manually), the SRU energizes all the outputs and, if necessary, supplies power to the batteries (charging phase).
• If the SRU is not supplying any power, the external or internal batteriesenergize all the outputs.
When the SRU, for any reason, stops supplying dc voltage, the batteries are the onlypossible dc power supply.
However, battery output voltages decrease over time.
So, when the battery output voltage reaches the first Load1 threshold, the PCU cutsoff power supply to the boards in the cabinet which are connected to outputs 1 and3. An alarm signal is generated on the Load1 threshold output.
If the battery output voltage continues to decrease and reaches the second Load2threshold, the PCU cuts off power supply to the boards in the cabinet which areconnected to outputs 2 and 4.
The Load2 threshold is the minimum permissible voltage at battery output:
typical value of Load1 threshold: 45 V ( ±2%)
typical value of Load2 threshold: 42 V ( ±2%)
If the SRU recovers power supply, the batteries are charging. When voltage is equalto 50.7 V, the PCU reconnects the cabinet boards with its four outputs.
Alarms
Alarm signals from the rectifiers in the energy subrack are concentrated in 3 singlesignals determined by logic OR:
ac fault alarm
dc fault alarm
over temperature alarm
Extreme temperature signals from the CEATS 1
A short circuit between the two CEATS 1 pins of the HOST interface connectorcauses thedisconnection of alloutputs connected to therectifiersandto thebatteries(only for the S8000 Outdoor BTS), and the generation of the Load1 alarm signal.
From --40 °C (--40°F) to 0°C (32°F), the rectifiers accept the mains voltage withoutdeterioration, but do not function.

Interface between the PCU and the RECAL board
The following signals are the interface between the PCU and the RECAL board:Load1 threshold (PCU internal alarm, also sent to RECAL)PCU protective devices (PCU internal alarm, also sent to RECAL)Battery on discharge (alarm)DC fault (alarm) AC fault (alarm)over temperature (alarm).
Battery operation of boards in the cabinet
The PCU enables the cabinet to run on internal batteries.
When the SRU, for any reason, stops supplying dc voltage, the batteries are the onlypossible dc power supply.
However, battery output voltage decreases over time.
So, when the battery output voltage reaches the first Load1 threshold, the PCU cutsoff power supply to the boards in the cabinet which are connected to outputs 1 and3. An alarm signal is generated on the Load1 threshold output.
If the battery output voltage continues to decrease and reaches the second Load2
threshold, the PCU cuts off power supply to the boards in the cabinet which areconnected to outputs 2 and 4.
The Load2 threshold is the minimum permissible voltage at battery output:typical value of Load1 threshold: 45 V ( ±2%)typical value of Load2 threshold: 42 V ( ±2%)
If the SRU recovers power supply, the batteries are charging. When voltage is equalto 50.7 V, the PCU reconnects the cabinet boards with its four outputs.
Alarms
A closedloop is provided on the RECAL board. If this loop is broken (open contact),the alarm is activated
The RECAL board is used for three alarm types:Internal alarm (28), which can be used only inside the cabinet.External non protected alarms (30), which can be used outside the cabinet.External protected alarms: there are 16 external alarms that can be optionallyprotected by oneExternal Alarm Connection module. This module includes two ALPRO boards (secondary protection) and 20 lightning protections (primaryprotection), necessary to protect 16 alarms and 4 remote controls. They concernall the alarms used by the customer.

The major internal alarms are the following:1 main breaker alarm6 rectifier 220 V/48 V alarms:
– ac alarm (individual) – dc alarm (individual) – over temperature alarm (common) – first voltage level on the battery (--45 V) – PCU breakers alarm (common) – battery on discharges alarm (common0
1 alarm for each F--Type converter (2)1 battery disconnected alarm3 alarms per VSWR (up to 6)
Note: The 3 alarms are monitored via 3 input pinsconnected to the Alarm Moduleof the BTS. The exception is BTS configuration with TX filter whereVSWR level 2 and level 3 alarms only are monitored (due to lack of inputport).
1 alarm per LNA/VGA (2)1 door alarm1 lightning protection alarm6 alarms for the user1 batteryemergency--stop alarm: this alarm is used to know whether thebatteriesare disconnected or not.• 2 alarms for the CDACS
The information returned from the sensors activates specific actions of the coolingsystems. The BTS is powered OFF if the temperature inside the cabinet is out of the0°C -- 70°C range.
1.4.3.2 C--ACMAIN power supplyTheC--ACMAIN ensure the ac distribution fromthe external ac to the rectifiers, theCDACS and the maintenance plug. It also provides EMC filtering and lightningprotections
The mains power supply of the cabinet comes from the ac box, located in the lowercompartment of the cabinet.
It supplies the rectifiers rack, the cooling system and the convenience socket of theBTS with ac power, each part being protected by integrated circuit breakers. Theac main box is European single--phase (see Figure 1--143 ) or dual--phase (seeFigure 1--144 ) .

2 BOARD DESCRIPTION
2.1 Power amplifier (PA)
The Power Amplifier (PA) amplifies the GMSK signal from a low--leveltransmission unit and sends it to the transmission coupler.
HePA is compatible with e--DRX (all frequencies) and DRX ND3 (900) and withthe indoor and outdoor S8000 and S12000 cabinets. The cabinet can contain amaximum of 12 HePAs.
Three types of PA are available : PA, ePA and HePA (High Power Amplifier). TheHePA can be used mixed with PA and ePA.
PA and ePA are class 5 amplifiers, that is, they can provide power of between 20 Wand 40 W. Nominal power is 30 W.
HePA is the BTS Power Amplifier with transmit power up to 60 W in GMSK andis Edge compatible.
HePA is compatible with S8000 CBCF and S12000cabinets (indoor + outdoor) and works with eDRX and DRX ND3. HePA is not compatible with DRX.
The HePA can be mixed with PA in step coupling configurations. It can be mixed with (e)PA in a normal cell if its power is being configured with a value that iscompatible with (e)PA (lower than 30 Watt).
The range of value of the OMC parameter ”bsTxPwrMax” that sets the power of the TRX, already permits to configure power up to 60 Watts.
The HePA is differentiated at the OMC from PA and ePA; in the same way the ePA is differentiated from the PA.
It contains its own dc/dc converter and contains a microcontroller which allows itto dialogue with the low--power transmission module. This function makes itpossible to move the power amplifier to the top of the tower if necessary.
2.1.1 Amplifier alarms
The power amplifier provides several alarms:
an overtemperature alarm, whose threshold is set in the PA
an overvoltage alarm, whose threshold is set in the PA
an alarm indicating that the PA output reflected power is exceeded
This alarm is triggered when the reflect power exceeds 6W.
an alarm dedicated to the dc/dc converter

2.2 ALCO boardThe ALCO is the alarm management unit used with the BCF Cabinet(S8000 Indoor) or the BCF Unit (S8000 Outdoor).
TheALCO board collectsand managesinternal and external BTSalarms. Theboardhas a PCM interface to allow a connection between the BCF and certaintransmission couplers.
There is one ALCO board per cabinet.
2.2.1 Functional description
The ALCO board is comprised of several function blocks (see Figure 2--5 ):The CU block is the board’s central management unit.The communication block provides a link with the CSWM board over the O&Mbus.The board groups communication interfaces with:• the BCF, by means of the internal private PCM link• the transmission coupler(s), by means of the private PCMThe alarm block manages alarms.The test block includes several test interfaces.
The power supply block converts the 48 V dc power supply distributed by theBTS to 5 V dc and 12 V dc.The identification and LEDs block identifies the cabinet number and boardversion, and controls signaling LEDs.The private PCM block is not connected to the other function blocks. It consistsof an interface between theGTWboard andcertain transmissioncouplers. It alsohas a J64 interface, using TS 25 of the first PCM.
2.2.2 Alarm management
The ALCO board manages three types of alarms:
internals alarmsunprotected external alarmsprotected external alarms
2.2.2.1 Internal alarms
The ALCO board is designed to detect up to 56 internal alarm logical signals(0/+5 V). An alarmis detectedwhenthe voltageexceedsa threshold of 2.5 V. Whenno alarm is detected, a reference zero--volt is applied to the threshold comparatorinput. These connectors are protected against power surges of less than 57 A for aperiod of 1 ms, and against power surges of less than 180 mA at all times.

2.2.2.2 Unprotected external alarms
The ALCO board canmanage 32 unprotected external alarms, the same electricallyas the internal alarms. These alarms are intended to be connected inside the cabinet,or near the cabinet in a protected environment, that is, not exposed to majorelectrical power surges.
2.2.2.3 Protected external alarms
The ALCO board protects up to 16 external alarms which are 12 mA current loops. An alarm is detected when a loop opens. These inputs are protected by the ALPROboard, a special protection board inside the BTS.
2.2.2.4 Analog input channels
The ALCO board reads four analog channels (voltage 0 to 5 V) converted to digitalsignals by an eight--bit, single--pole analog--to--digital converter. These inputs areprotected against voltages of several tens of volts.
2.2.2.5 Remote controls
Four dry--contact relays are controlled by the ALCO board and protected by the ALPRO board. They are all --or--nothing relays with a maximum current of 80 mA
and a maximum voltage of 72 V dc.
2.2.3 Physical description
This section describes the front panel, the LEDs, the connectors, and the electricalcharacteristics of the ALCO board.
2.2.3.1 Front panel
The front panel of the ALCO board has the following:
one reset button
three LEDs
eight connectors
The reset button allows a hard reset of the board.
The front panel of the ALCO board is shown in Figure 2--6 .

2.3 RECAL board
2.3.1 Functional description
The RECAL board is the alarm management unit usedwith the CBCF. The RECAL collects external and internal alarm loops and alarms associated with OEMequipment.
A slave of the CBCF, the RECAL board sends alarms to the CBCF over a PrivatePCM link. The CBCF signals the BSC when there is an alarm.
There is one RECAL board per cabinet.
The following functional blocks of the RECAL board are shown in Figure 2--7 :
control unit
alarm interfaces
communication interfaces
power supply
2.3.1.1 Alarm management
The RECAL board collects three types of alarms:
internal alarms
unprotected external alarms
protected external alarms
Internal alarms
The RECAL board detects up to 56 internal alarms logical signals.
Internal alarms are wire loops that can only be opened or closed by dry contacts oropen collectors.
A closed loop forces a low logic level (less than 1.35 V) on the trigger output, whichindicates that there is no alarm. An open loop forces a high logic level (greater than3.15 V) on the trigger output.
The CPU runs polling sequences to recognize the alarm state.

Protected external alarms
The RECAL board detects up to 16 protected external alarms. These alarms can beused outside the cabinet by adding two ALPRO boards (for S8000 indoor/outdoorBTS) or one ALPRO board (for S8003 indoor BTS) which each manage 8 alarms.
A closed loop forces a low logic level (0 mA) on the optocoupler collector,
indicating that there is no alarm. An open loop forces a high logic level (5 mA) onthe optocoupler collector, indicating that there is an alarm.

Note that due to the absence of the battery remote controller (BRC) for the S8000Indoor BTS and the S8003 indoor BTS, the application of the battery remotemaintenance feature only consists in providing a possibility to use an externaltelecommand to switch off the main power and operate on batteries and to switchback to main power.
The operation is performed via the external remote commands (close/open relay)accessible via the ALPRO box connected to the EXT. P. connector of the RECAL board.
TheEXT. P. (external protectedalarm) connector provides pins ETC0A (pin17)andETC0B(pin18), both connected to an internal relay ETC0 within the RECAL board
(see Table 2--24 ).
2.3.1.2 Analog to digital inputs
The RECAL board reads four analog channels (voltage 0 to 5 V dc) that areconverted in digital signals by an eight--bits signal into a analog/digital converter.
2.3.1.3 Remote control outputs
Four remote control relay outputs are provided with a maximum current of 80 mA and a maximum voltage of 72 V dc.
2.3.2 Physical description
This section describes theLEDs, connectors, and the electricalcharacteristics of theRECAL board.
2.3.2.1 Front panel
The front panel of the RECAL board has the following:
one reset button

2.3.2.4 Electrical characteristics
The RECAL board is powered by a nominal 48 V dc. The nominal supply currentis approximately 600 mA.
A dc/dc converter (48 V to 5 V) on the board supplies logic circuits with +5 V dc.The +5 V dc supply is available on the EXT.P external connector (and P5 internalconnector) for the possible heating resistors mounted on the ALPRO boards.
A second dc/dc isolated stages converter (5 V to 12 V) provides external alarmdetection circuits with +12 V dc isolated supply.
A CEM filter is designed on the board between 48 V dc input and the primary stageof the dc/dc (48 V to 5 V) converter.
Its maximum consumption is 15 W.

2.4 ALPRO board
The ALPRO board protects up to eight external alarms and up to two remotecontrols of the ALCO or RECAL board.
2.4.1 Principle
The external alarms andremote controls are intended to be connected to equipmentoutside the cabinets. This equipment may be connected, temporarily orpermanently, to outside line conductors affected by electrical disturbances. The ALPRO board protects against these disturbances.
One ALPRO board protects half of the external interfaces available in the ALCOor RECAL board. There may therefore betwo ALPRO boards for one ALCOboard.Depending on how many external alarms are used, one or two ALPRO boards maybe installed.
Note: Depending on how many external alarms are use and what the S8000Outdoor or S8003 Indoor BTS configuration is available, one or two ALPRO boardsmay be installed.. For S8003indoor BTS, only oneALPROboard may be installed (one ALPRO board protects 8 alarms maximum).
2.4.2 Description
The ALPRO board (see Figure 2--9 presented in S8000 Outdoor configuration orin S8003 indoor configuration) provides only secondary protection. Primaryprotection devices are associated with the board to protect the lines themselves. A cable linking the board ground to a cabinet ground bar discharges energy caused byoutside disturbances.
2.4.2.1 External alarm protection circuit
The first part of the external alarm protection circuit comprises a surge arrestor andthermal resistors, which protect the board against power surges andlimit thecurrentin wires and connectors.
The second part limits the voltage and current returning to the ALCO or RECAL board. It consists of transils and thermal resistors.
2.4.2.2 Remote control protection circuit
The first part of the remote control protection circuit comprises a surge arrestor andthermal resistors, which protect the board against power surges andlimit thecurrentin wires and connectors.
The second part protects the relays and connections of the ALCO or RECAL board.It consists mainly of thermal resistors.

2.5 F--type converter
2.5.1 Principle
The F--type converter converts a 48 V dc voltage into twopower sources, --15 V and+15 V. It powers the radio equipment such as the Low Noise Amplifiers (LNA), thevariable gain amplifiers and the VSWR measuring devices.
2.5.2 Description
The F--type converter has a switch on its front panel that can be used to disconnect
the input voltage. It also has two outputs that can be connected in parallel withidentical outputs of another F--type converter.
2.5.2.1 Input voltage
Nominal input voltage: 48 V (40.5 V to 57 V)
2.5.2.2 Output voltages
The two output voltages supplied by the converter are as follows:
Source 1:
Nominal voltage: +15 V Nominal current: 7 A
Source 2:
Nominal voltage: --15 V Nominal current: 4 A
Output voltages can be individually adjusted up to +15% and --5% of nominalvoltage.
2.5.2.3 Alarms
Several alarm signals can be generated, in the following cases:
One of the two output voltages is either lower than the Low Voltage Limit (LVL)or higher than the High Voltage Limit (HVL). These limit voltages are:
• LVL: 13.25 V ± 0.25 V
• HVL: 18.5 V ± 0.5 V
The switch on the front panel is set to ”OFF”.
The converter temperature is too high.
Finally, an event alarm is generated when there is a logic OR between the otheralarms.

2.5.3 Front panel
The F--type converter front panel has several connectors and LEDs (seeFigure 2--10 ).
2.5.3.1 LEDs
Two green LEDs provide information on the status of the converter.
2.5.3.2 Connectors
Two connectors are on the front panel of the converter:
A female, Sub--D, 15--pin connector supplies output voltages and alarm signals.
A male, 3W3, Sub--D connector receives input voltages.

2.6.1.2 Reception amplifier
The reception signal amplifier, also called the LNA--splitter, has two functions:
amplifies the signal from the antenna using a Low Noise Amplifier (LNA)
splits the signal from the antenna into four signals
The LNA--splitter has the following attenuation or gain values:
The LNA has a nominal gain of 28.5dB (GSM 900) and 32 dB(GSM 1800/1900).
The two splitter stages cause attenuation less than 7 dB.
A 2dB attenuator handles differences in cable attenuation between the twoextension outputs (EXT) and the two internal outputs (INT). The two extensionoutlets, which are not used at present, will make future configuration upgradespossible.

2.6.1.3 Hybrid transmission coupling
According to the hybrid coupling type, transmission coupling consists of a singlehybrid coupler for H2D configurations or three hybrid couplers mounted in twostages for H4D configurations.
The two--way hybrid coupler (H2D) consists of:two isolators, one at each input port, which allows the protection of the Power Amplifier (PA) against reflected signals, and also permits the isolation necessarybetween transmittersa hybrid coupler, which combines two transmission signals on only one port.
This subsystem is part of the RF Combiner module (H2D, or H4D).
Themaximum attenuation is an RF Combiner moduleis dedicated to onefrequencyband.
When any transmission coupling system is requested (in the case of one TRX perantenna), the Tx--Filter (TxF) module can be used with two duplexer--only (D)modules in order to provide Rx main and diversity signals.
The Tx--Filter module is dedicated to one frequency band.
Refer to Paragraph 2.7 “Tx--Filter module” on page 2--75 for information about theTx--Filter.
2.6.1.4 VSWR--meterThe VSWR--meter can be included as an optional unit in the RF Combiner moduleor in the Tx--Filter module.
The VSWR--meter allows the signal strength of the voltage standing wave ratio(VSWR) to be monitored on the antenna connector and to verify the connectionbetween the antenna and the BTS. This module needs BTS signals transmission tobe able to switch on (no alarm with “Receive antenna” only)
The VSWR--meter receives transmitted and reflected signals sampled through twodirectional antennas located inside the duplexer unit or Tx--Filter unit.
Note: The 3 alarms are monitored via 3 input pins connnected to the AlarmModule of the BTS. The exception is BTS configuration with TX filter where VSWR level 2 and level 3 alarms only are monitored (due to lack of input port)
The transmit and receive signals are first converted into two dc voltages by usingenvelope detection. Two logarithmic amplifiers, one for transmit power signal, andone for reflected power signal, then amplify both converted signals.
The two channels are added and subtracted to obtain the stationary wave ratio. Thisvalue is compared to three thresholds (1.7:1, 2:1, and 3:1), each of which triggersan alarm if it is exceeded.

2.6.1.5 Remote tunable cavity combiner
The remote tunable cavity combiner is used for the 1800 GSM frequency band. Itis only available for the S8000 Indoor BTS equipped with a CBCF module.
It consists of eight--waycavities; each of them tuned at the frequency correspondingto the transmitter connected to it.
In cavity coupling mode, the transmiter is set to work at a single frequency (thecoupler frequency). It permanently scans all FH bus links coming from the FrameProcessors. When it detects an indication that data is to be transmitted on its ownfrequency, it reads and transmits it on its radio channel. Baseband frequencyhopping requires as many transmitters as the number of frequency used. Of course,at any time the frame processor uses just one transmitter, which means that othertransmitters may be used for other frame. processors, if required.

2.7 Tx filter module
The purpose of the Tx--Filter (TxF) is to filter the transmitted signal and to protectthe power amplifier (PA). The TxFdoes not contain a transmission couplingsystemor a receiver filter.
The Tx--Filter module is composed of (see Figure 2--20 ):
a transceiver filter unit
a coupling system dedicated to the VSWR--meter
an optional VSWR--meter that monitors the link between the BTS and theantenna.
The Tx--Filter module is used with the duplexer--only RF Combiner (D) to extendconfigurations beyond two DRX or e--DRX or DRX--ND3 per cell. The Tx Filterdoes not perform reception functions and must be used with the RF Combiner (D)to ensure reception distribution.
TheTx--Filter modulecanbeequipped with an optional VSWR--meter whichsharesthe same front panel so that there is only one unit to plug into the BTS rack.
With or without the optional VSWR--meter, the Tx--Filter module is half the sizeof the two--way hybrid (H2D) and duplexer--only (D) RF Combiner.
2.7.1 VSWR--meter
The function of the VSWR--meter (see Figure 2--21 ) is described in the section“RF Combiner”.
The VSWR--meter connectors on the front panel of the Tx--Filter are the same asthose of the RF Combiner and are described in the section “RF Combinerconnectors”.
Althrough the VSWR--meter delivers three alarm lines, only two are reported to theOMC--R because of COMICO constraints.
These alarm thresholds correspond to 2:1 and 3:1 VSWR values.
Note: The 3 alarms are monitored via 3 input pins connnected to the AlarmModule of the BTS. The exception is BTS configuration with TX filter where VSWR level 2 and level 3 alarms only are monitored (due to lack of input port)

2.8 BCF unit
The BCF performs functions common for a site.
Paragraphs 2.8.1 to 2.8.6 describe the following boards contained in the BCF Unit(S8000 Outdoor) and BCF Cabinet (S8000 Indoor):
PCMI
GTW
CSWM
DSC
SYNCBCF Converter
PSCMD
The BCF also manages its alarm management unit, the ALCO board.
2.8.1 PCMI board
The PCMI board is the PCM interface. It makes the physical link between the BSCand the BTS through the Abis interface.
The PCMI board is the interface between internal PCMs and external PCMs. Itcontrols the transmission and reception of frames.
It has two PCM junctions (that is, two external PCMs linked to two internal PCM).
The two PCM junctions of the PCMI board are controlled by a processing unit which also makes the link to the CSWM control board.
The PCMI board receives the following signals from the CSWM board:
The PCM bus carries clock and frame alignment signals, as well as transmissiondata (conversion of single--pole signals to two--pole signals).
The O&M bus is a 9600 bit/s asynchronous serial interface. It carries controlandboard addressing signals, and insures data send/receive links.
The PCMI board, over a V11 interface, sends to the CSWM board reception data(conversion of the two--pole signal to single--pole signals), and the two receptionclock signals.

2.8.1.1 Functional description
The functions used by the PCMI board are coding and decoding with detection of code violations, and management of CRC code multiframes implemented by thesoftware.
Whereas transmission alignment is generated automatically, reception alignment isdone by frame alignment and multiframe alignment:
Frame alignment is lost after three consecutive incorrect words or threeconsecutive odd frames with bit 2 of time slot 0 equal to 1. This triggers the falseframe counter and sends the alarm indication signal (AIS) to the system.Re--alignment is done when a correct frame alignment word is received,
followed by the correct odd frame TS 0, followed by a correct frame alignment word.
CRC multiframe alignment is lost if frame alignment is lost. Re--alignment isdone when two correct multiframe alignments are detected separated by a timeslot of n x 2 ms.
The PCMI board uses the following alarms:
LOS: Loss of Frame Alignment
AIS: Alarm Indication Signal
NOS: NO Signal
RRA: or RAI Remote Receive Alarm or Remote Alarm IndicationSKP: SKiP indication received
CRC: Cyclic Redundancy Check error rate, for each CRC counter read
FE: Frame Error rate, for each frame error counter
2.8.1.2 Front panel
The front panel of the PCMI board has the following elements (see Figure 2--22and Figure 2--23 ):
The green +5 V LED is on to indicate that the board power supply is ON.
The yellow BIST LED is on to indicate that the self--tests are being carried out.
The green RDY LED is on to indicate that the board is operating correctly.
A RESET pushbutton is used to reset the board to zero.
Two rows of seven red LEDs display thestatus of the PCM alarm junctions, withone LED per PCM alarm.
Two eight--pin connectors select operation in either NORMAL mode (one plugin“XL”position for transmit pathand one plug in“RL” position for receive path)or in LOOPBACK mode for tests (one plug in “LP” position to connect thetransmit path to the receive path).

the GSM TIME bus
a CSWM processor that supplies the reference time

2.8.4.2 Operation
Processor functions
The processor does the following:controls the frequency--locked loop (FLL)manages switch over proceduresenables communication with the CSWMmanages GSM time
FLL management
The reference time is generated by the external frequency 4096 kHz reference, a
VCXO oscillator, frequency dividers, and frequency--locked loop (FLL).The processor emulates a high--gain filter (wideband) in the locking phase to ensurerapid convergence. When theFLL is locked, gain isreduced (narrowband) to obtainthe stability specified in GSM recommendations.
When the processor detects a loss of reference time, it stops the FLL and lockdetection functions and controls the VCXO using the last correct value. Frequencyis then matched to the VCXO value.
When the 4096 kHz reference time is regained, lock detection and the FLL functionare reactivated in the narrow or wide band, depending on the nominal frequencydeviation.
If there is no 4096 kHz reference at start-up time, the processor sets the controlvoltage in the middle of the accepted range and stabilizes the frequency by movinginto the narrow band.
Alarms
To avoid untimely master/slave switch over, alarms are managed on front edge.
This, status changing and event reports only occur on front edge. There are twotypes of alarms:
direct alarms, switching directly master/slave:•
SW fail: when a software stop due to watch dog control isdetected (directly to exchange logic)• Clock fail: when the frequency clock generated by timing
source built--in VCXO has failed (directly to exchange logic)software alarms, demanding a master/slave switching provided the slave ispresent without alarm:• H4M fail: loss of the 4096 kHz signal coming from CSWM• ALTBUS: hardware alarm on the GSM TIME bus• TIMEDATA: software alarm concerning the value of the GSM TIME
These two last alarms are bounded.

Inter--board signal exchanges
There are two types of signal:
synchronization signals used to synchronize master and slave counters
switch over signals
2.8.4.3 GSM TIME bus
This bus connects the SYNC card to the GTW unit. It carries data defining the BTS“local time”.
It distributes three signals (differential pairs):
a 577--µs signal
a transfer clock signal
a serial data signal
The master SYNC can read and write on the GSM TIME bus.
It reads back the previously written data at regular intervals and compares the twovalues to detect malfunctions. In case of mismatch, the processor triggers switchover.
The slave SYNC can only read the GSM time bus and uses it to synchronize its owncounters on the master time.
2.8.4.4 CSWM interface
The CSWM supplies the reference time at 4096 kHz. The SYNC board detectsreference time loss and informs the CSWM via the O&M bus. GSM time continuesto be generated using a fixed VCXO voltage.
2.8.4.5 O&M bus interface
It is used by the CSWM master and the two SYNC boards for communication. Thefollowing messages are exchanged:
Status request
The CSWM sends status requests when self--tests are run. The SYNC board sendsback its status (master or slave), self--test results (BIST), alarms, and faults.
Events
When faultsor alarmsaredetected, theSYNC boardgenerates unsolicited messagesand forwards them to the CSWM.

Switchover request
The CSWMcan request the master SYNC to switch over and operate in slave mode.The master checks before switching over that its counterpart is present and that noalarm conditions exist. Depending on the results, switchover may or may not betriggered.
Two responses are possible:
Master and slave have switched over.
Master and slave have not switched over because of an alarm condition on thecounterpart SYNC board.
GSM time request
When CSWM sends time requests, two responses are possible:
GSM time, especially: T1, T2, T3, and TN (GSM 05.02 recommendation),
• T1: hyperframe counter, 11 bits on two bytes:
0 0 0 0 0 T1 T1 T1T1 T1 T1 T1 T1 T1 T1 T1
• T2: module 26 counter, 5 bits on one byte,
0 0 0 T2 T2 T2 T2 T2
• T3: module 51 counter, 6 bits on one byte,
0 0 T3 T3 T3 T3 T3 T3
• TN: module 8 counter, 3 bits on one byte.
0 0 0 0 0 TN TN TN
A flag is added (7E in hexadecimal) to detect a possible serial link loss.
no results available. The synchronization board that waspolled is not the master.
Version request
The CSWM can request the version reference and the SYNC returns the relevantnumber.

2.8.5 BCF converter
2.8.5.1 Principle
The BCF converter is a dc/dc converter located in the BCF cabinet subrack.
2.8.5.2 Description
Input voltage
Nominal input voltage: 48 V or 60 V (40 V to 72 V).
Output voltage
Nominal output voltage: Un = 5.2 V ± 2%.
Nominal output current: In = 12 A.
Parallel mode
The converter outputs are wired in parallel with the outputs of another, identicalconverter (in N+1 redundancy). In this way, a fault on one of the converters onlyreduces the available output current.
Protections
Input circuit
The ON/OFF switch on the converter front panel cuts off the input voltage. Theconverter is also protected against inversion of the input voltage.
Output circuit
The converter is protected against output short--circuits and against overvoltage.
When the output voltage reaches (120 ± 4%) of nominal voltage, the output voltagepasses to 0 V. Manual reinitialization by means of the ON/OFF switch on the frontpanel is necessary to return to a voltage close to the nominal voltage (if the sourceof the fault has disappeared).
Alarms
Two alarm loops can generate a signal in the following cases:
The output voltage is less than [Un -- (10 ± 4)%].
The output voltage is greater than [Un + (20 ± 4)%].

2.8.6 PSCMD board
2.8.6.1 Principle
The PSCMD board controls simultaneous energization of the three 48 V/5 V--BCFconverters. To do so, it uses the remote control inputs of the BCF convertersreceived through a three--pole switch.
The BCF converters must be in the “ON” position before the switch on the PSCMDboard is set to the ”ON” position.
There are four jumpers, TYAL0 to TYAL3, on the side of the PSCMD board. They
are used to set the TEI.
2.8.6.2 Front panel
The front panel of the PSCMD board has a three--pole switch and three LEDs, oneper BCF converter (see Figure 2--31 ).
2.8.6.3 Physical characteristics
The power supply voltage is 5 V, with a tolerance of ± 5%.
2.8.6.4 BCF TEI configuration
BCF TEI numbering rule
The BCF TEI number (Terminal Equipment Identifier) depends on the BTS rank within the network configuration.
The commissioner must know the type of the configuration (star, chain, loop) as well as the location of the BTS in this configuration:
star configuration: all BTSs have the same TEI value
chain and loop configurations: Increasing TEI values are assigned to the BTSsaccording to their positions in the chain or the loop.
By convention the TEI value 0 is allotted to the BTSs in star configuration and tothe first ranking BTS in chain or loop configuration.
BCF shelf number
The BCF shelf number is obtained by calculating the 2’s complement of the fourlow--order bits of the BCF TEI number (in binary logic exclusive--OR with value1111).

2.9.1 Functional description
The CBCF Module performs functions common for a site and also manages itsalarm management unit, the RECAL board.
A S8000 BTS contains either a BCF (Unit or Cabinet) or a CBCF Module.
A S8003 BTS contains a CBCF module only.
The base common functions of the BTS are performed by two main CBCF Moduleboards: the CMCF and the CPCMI.
The CMCF board performs the concentration, switching, and synchronizationfunctions of the BTS. The CPCMI board ensures the interface between the externalPCMs of the Abis interface and the internal private PCMs.
PrivatePCMlinks connect theCBCF (viathe CMCF)to theother BTScomponents.The CBCF also uses private PCMs for internal communication between CBCFboards.
The boards and their functions are identified in Table 2--55 .

2.9.4 CPCMI Board
2.9.4.1 S8000/S8002 CPCMI board
Dependingon the requirements, the CBCF Module cancontain one to three CPCMIboards.
This Compact PCM interface board handles two PCMs. Both PCMscan be usedforthe system Clock of the BTS.
2.9.4.2 Functional description
The CPCMI board ensures the interface between the external PCMs of the Abisinterface and the internal private PCMs. This interfacing task corresponds to anelectrical level translation and a frame format conversion depending on the kind of Abis link (PCM E1/T1 or HDSL).
There are two types of CPCMI boards available used in accordance with the typeof Abis interface:
CPCMI--E1
CPCMI--T1
Note: The CPCMI--E1 type applies to the only S8003 Indoor BTS.
The core of each board is generic and common to all, but each uses a different lineinterface.
The CPCMI uses the n+1 redundancy scheme depending on:
the number of required TSs
the drop and insert scheme
the number of CPCMIs present in the package (three maximum)
secured loop feature is activated or not
The functional characteristics of the E1 and T1 boards are summarized inTable 2--57 .

Synchronization
The timing signal is extracted from the PCM clock and sent to the CMCF (RCLK).The local time is sent to the CMCF if there is no PCM timing signal (RCLK =HLOC).
The CMCF selects one signal from the six received (one per PCM link) andredistributes it as a reference for all Abis transmissions (TCLK). This signal is alsothe long term reference used to create the H4M timing reference.

2.9.5 CMCF board
The CBCF Module contains one or two CMCF boards. One CMCF board allowsoperation in simplex mode, while two CMCF boards provide fully redundantduplex operations.
2.9.5.1 Functional description
The CMCF Board performs the following functions:
synchronization of the BTS, through
• selection of PCM clock
• PCM link frequency measurement• input of external clock
• generation of the reference frequency for the DRX or e--DRX or DRX--ND3
• generation of GSM Time
switching
signalling concentration
communication with the BSC and with O&M slaves (e.g. DRX, e--DRX,DRX--ND3, CPCMI, RECAL)
Each CMCF board contains two dc--dc converters that perform the functionsperformed by the BCF Converter and the PSCMD board in the BCF.
2.9.5.2 Synchronization (SYN)
An oscillator provides the SYN function. The slave CMCF operates in aphase--locked loop so that its H4M clock is in phase with the master CMCF. Thisensures that synchronization is maintained during a CMCF switchover.
GSM Time
The processing unit writes the GSM time (72 bits) every 60 ms and the value isstored in the matrix at a rate of one bit per frame. Both the master and slave CMCFre--read the information in the matrix of the master CMCF, which ensures that GSMtime is synchronized on both CMCF boards.

Electrical characteristics
The CMCF board receives a 48 V dc power supply and generates other requiredvoltages from this single source.
Two dc--dc converters in each CMCF board perform the following conversions:
48 V to 5 V48 V to 12 V
5 V to 3.3 V
The 5 V power supply is required for most CMCF components, including bothprocessing units. It has an 8 W power consumption.
The oscillator and DAC parts of the CMCF board require a 12 V power supply. Theoscillator consumes1 W during maintenance and up to 10 W in itspreheating phase.
The 3.3 V power supply is used strictly for the DRAM.
Synchronization
The CMCF provides synchronization for the radio part of the BTS.
The CMCF hardware allows the selection of a clock from the following sources:
six clock signals taken from external PCM links (from the CPCMI)CMCF master clock
The long term stability of the external PCM link clock ensures the accuracy andstability required.
A frequency meter function on the CMCF board measures the clocks to determinetheir validity.
GSM Time channel
The SYN function generates and distributes the GSM--time channel on the PrivatePCM. TheGSM--timeis thelocal BTStime, sothecounters arearbitrarilyset to zeroafter turning on the CMCF.
The GSM time channel emission is dedicated to a special hardware system.
Synchronization between master and slave processing units
The master processing unit fully synchronizes the slave processing unit.
Fully synchronous GSM--time emission is performed through a pulse signal sentfrom the Master GSM--time generation hardware system to the slave system.
External synchronization connection
An external synchronization interface is provided directly on the SYN part of theCMCF. The software selects the synchronization origin.

2.10 DRX, e--DRX, DRX--ND3 module
Themoduleprocesses receptionand transmission signals. The modulehasa receivesensitivity of --110 dBm or --108 dBm.
The Network Identification of BTS equipment feature consists in finding a way todifferentiatefroma system point of view e--DRXand DRX--ND3for DRX; ePA andHePA for PA; CMCF phase 1 for CMCF phase 2 EDGE feature implementation.
This feature also allows the addition of new equipment: e--DRX, DRX--ND3, ePA and HePA on sites without any modification of the configRef (DLU).
The DRX--ND3 is designed with the same logical board as the e--DRX.
From a radio point of view, the DRX--ND3 is not able to support EDGE 8PSK modulation. The DRX--ND3 is not an EDGE ready hardware.
The DRX--ND3 can be used together with DRX and/or e--DRX.
2.10.1 DRX front panel
The DRX front panel has the following elements (see Figure 2--40 ):
a 26--pin power supply connector (PWR)
a 66--pin connector for the private PCM (FH--PCM)
a 50--pin test connector (TEST)a transmission signal output (TX OUT)a diversity reception signal input (RXD IN)a main reception signal input (RXM IN)

2.11 RX--splitter
The RX--splitter amplifies a reception signal and splits it into several signals thatit sends to the receivers.
2.11.1 Principle
The RX--splitter consists of the following elements (see Figure 2--42 ):
A two--stage, four--channel splitter splits the signal from the LNA--splitter intofour identical signals.
Four Low--Noise Amplifiers (LNA) each amplify one channel.
Four resistive attenuators adjust the gain to the required value on each LNA channel.
A remote amplifier controlling the power of the incoming signal. The DRX ore--DRX or DRX--ND3 supervises the amplifier and sends the information to theBSC.
Each channel of the RX--splitter is connected to a different receiver. The receiversupplies the LNA of the channel to which it is connected by means of the RF cable.The four channels are therefore supplied independently of one another.
Channels which are not connected to any receiver are not supplied with power, andso need not be adapted by a 50 Ω termination.
Nominal gain on the four outputs is + 9.2 dBm (GSM 900/850), + 8 dBm (GSM1800/1900).
2.11.2 Consumption
The RX--splitter is supplied with +12 V dc + 5% or +5.5 V dc + 5% (GSM1800/1900). Its maximum consumption is 40 mA (GSM 1800/1900) 50 mA forGSM 900and GSM 850. The receivers to which it is connected trip an alarm if thislimit is exceeded.
2.11.3 RX--splitter front panel
The front panel of the RX--splitter has the following elements (see Figure 2--43 ):
Four RX connectors each supply a signal to a receiver which supplies them withvoltage.
An IN connector is used by the RX--splitter to receive the reception signal.

2.12.1 Energy Supply Module (ESM) (five--rectifier type)
The Energy Supply Module (ESM) is an energy distribution system that suppliespower to the different modules of the S8000 Indoor BTS. It is powered with singlephase 220--240 V ac from the mains, and delivers a --48 V dc to the S8000 Indoor.
The ESM is composed of a Power Controller Unit (PCU), 5 680W rectifiers (onefor redundancy), a climatic unit, and a battery pack. A common ac supply powersall the rectifiers through backplane connectors. The climatic unit is situated abovethe rectifiers and is composed of fans, a fan power board and air filters. Theseprevent the module from overheating.
The ESM can be installed underneath, on the side of or at a distance from the S8000Indoor. Two cables are situated on the right of the ESM, one from the mains, whichpowers the ESM, and one which is connected to the ALPRO board of the BTS, which reports the ESM alarms. The cable on the left of the ESM powers the BTS with --48 V dc.
2.12.1.1 PCU Description
The PCU contains the following outputs which supply the modules of the cabinet:
Output 1, which supplies the power amplifiers and F--type converters
Output 2, which is unused
Output 3, which supplies the climatic units
Output 4, which is unused
One common 0 V output
PCU Protections
The PCU outputs are protected by the following circuit--breakers:
• Output current 1: breaker L1 (50 A), (supplies BTS)
• Output current 2: breaker L2 (unused)
• Output current 3: breaker L3 (15 A), (supplies climatic unit)

• Output current 4: breaker L4 (unused)
When circuit--breakers L1 or L3 are tripped, an alarm signal is generated.
The power supply can also be cut off manually on either of the outputs. This is doneusing the circuit breakers on the front panel of the PCU.
Alarms
Various alarms are provided in the PCU to detect the following situations:
acfault: whenthe acsupplyis interruptedor isoutside of the 172 V -- 276 V range(single alarm for all five rectifiers)
dc fault: when the dc output supply is outside of the 40 V -- 58 V ( ± 0,5 V) range(single alarm for all five rectifiers) or if a temperature sensor is not properlylinked to the PCU
excessive temperature: the rectifier switches off when the maximum operatingtemperature is exceeded, and then starts again when the temperature has droppedback to normal (single alarm for all five rectifiers)
discharged batteries: local power cut trips an alarm
climatic unit fault
battery circuit--breaker fault
lightening protector fault
All Alarms are supervised through the ALPRO module, which is situated at the topof the S8000 Indoor. A cable on the right of the ESM connects the ESM alarms aretherefore reported to the OMC as external alarms. The allocation of these alarmsis defined by the client.

2.13 Battery Remote Controller
CAUTIONGSM--R specific
Indicates that specific equipment and specific software (such asspecific software in the BSC) dedicated to Railway application isusedand that therefore thefeature isnot available forall preliminaryGSM users.
The battery remote controller (BRC) is requested to:switch off the BTS rectifier. This operation will first check that the batteries areoperational in order to avoid any loss of service.
switch the BTS rectifier back on, when a safety non adjustable low voltagethreshold has been reached or upon a remote command from the RECAL board(relay open).
The BRC controlled by the RECAL board, offers two new features forS8000/S8002 BTS equipped with CBCF module only:
the battery remote maintenance
the battery status monitoring (will be available for GSM--R phase3)
2.13.1 Battery remote maintenance
The aim of this feature is to increase the battery life by performing periodicdischarges. To realize theoperation, the BTSrectifiersareswitched offand theBTSis forced to operate on batteries. Then, when a given low voltage threshold isreached, the rectifiers are automatically switched back on.
2.13.2 Battery status monitoringThis feature will be available for GSM--R phase 3.
2.13.3 Location
Due to the fact that the BRC is located in a rectifier shelf (see Figure 2--53 ),maximum number of rectifiers on a S8000 Outdoor BTS is limited to five. In order,to respect rectifiers N+1 redundancy, the configurations are limited to six DRX ore--DRX or DRX--ND3 per cabinet.
For S8002 BTS, the maximum number of rectifiers is three (N+1 redundancy).

Each message is transmitted in synchronization with the 4Fbit clock and includesthe following:
the system time in six bytes (flag included)the address of the DRX or e--DRX or DRX--ND3 that transmits the informationin one bytethe code of the send frequency on 10 bitsthe send power commands in one bytethe NRZ message of the send data in 19 bytes
Up to 16 transmitters can be connected to this bus.
For multi--cell sites, all the cells can be connected onto a single FH bus or there maybe one FH bus per cell, depending on the capacity of the site.
3.1.3.2 Private PCM
Up to six private PCMs transport data between the DRX or e--DRX or DRX--ND3and the BCF unit or CBCF module. Each Private PCM supports up to four DRX ore--DRX or DRX--ND3. Each Private PCM has a 64 kbit/s time slot (TS) distributedto all DRX or e--DRX or DRX--ND3 and carries the GSM TIME signal (TS31).
Each private PCM allocates the following time slots (TS) for each DRX or e--DRXor DRX--ND3:
three TSs (64 kbit/s logical channels) of transparent data (traffic/signaling)one TS (64 kbit/s logical channel) processed by the gateway for the O&Mchannel, an adaptation of the O&M bus of the CSWM card
A group of six TSs, three of which are used, is allocated to each DRX or e--DRXor DRX--ND3, as follows:
Traffic Traffic O&M TXOML/RSL
1 2 3 4 5 6
TS 0 of the Private PCM is reserved for tests and supports no transmission channel.
A 4.096 MHz clock, slaved to the 4Fbit clock of the synchronization board, is usedfor bit synchronization of the Private PCM.
The O&M channel
The O&M channel, not availabale with the COAM version of the BTS, is carriedby a TS of the private PCM and supports O&M data of the TXs. It is a duplextwo--way channel. Each TX has its own O&M channel, present on the only privatePCM that links the TX to the gateway.
8/10/2019 411-9001-063 S8000 BTS Reference

PE/DCL/DD/0063411--9001--063
Standard 15.53/EN March 2005 Copyright © 1999--2005 Nortel Networks
The private PCM TS number of the O&M channel of a DRX or e--DRX orDRX--ND3 is unvarying in a given gateway configuration. This TS number acts asthe DRX or e--DRX or DRX--ND3 address for the gateway/DRX or e--DRX orDRX--ND3 link.
O&M data are sent only on the O&M channel of the DRX or e--DRX or DRX--ND3selected on the bus. Only the data received on this O&M channel are redirected tothe O&M bus.
The GSM TIME channel
This one--way logical channel transports the GSM time signal to each DRX or
e--DRX or DRX--ND3. It is carried by bit 7 of TS 31 of the private PCM. Thetransmission speed of the resulting transmission channel is 8 kbit/s.
A correction value is sent to each DRX or e--DRX or DRX--ND3 over the OML linkof the private PCM. This value corresponds to the delays caused by propagation.Each DRX or e--DRX or DRX--ND3 can therefore locally regenerate a synchronousGSM TIME bus with the BCF subsystem bus.
The refresh period must be a multiple of an occurrence between theGSM time base(577 µs) and the PCM time base (125 µs). The selected refresh period is 60 ms.
Such a 60--ms frame contains three parts:
Synchronization flag Useful data Filler bits
3.1.3.3 GSM TIME bus
Principle
The GSM Time bus is a V11 serial bus used in the BCF Unit to link the SYNC and
GTW boards.The data it conveys define the “local BTS time”. The serial format includes a flagto detect any break in the link. Moreover it provides a “strobe” every 577 µs thataccurately matches the start of each time slot.
Interface signals
The GSM TIME bus supports three types of signals. These three signals, which aregenerated by the synchronization unit, are transmitted in differential mode.

3.1.3.4 Internal PCM bus
Principle
The V11 bus is located between the switching matrix and the following units:
PCM Interface units (PCMI)
Data Signaling Concentration units (DSC)
GaTeWays (GTW)
The 16 internal PCMs are synchronous links at 2 Mbit/s on which the data areorganized in 125-- µs frames divided into 32 time slots of eight bits each. A PCM
is a time division multiplexed link that supports 32 channels with a throughput of 64 kbit/s.
Interface signals
The signals used are the following:
• MICR : Receive PCM in master--to--slave direction
• MICE : Transmit PCM in slave--to--master direction
• SY : 8 kHz negative frame synchronization pulse
• H4M : 4.096 MHz timing clock
3.1.3.5 O&M bus
Principle
The O&M bus is a V11 asynchronous master--slave type bus that is subject tophysical addressing. It interconnects all units of the BCF subsystem and the TXsthrough the private PCM between the GTW and the DRXs. The CSWM acts asmaster.
The bus enables users to do the following:
set up the initial configuration and reset it
measure and control system status
retrieve alarms
force each bus subscriber to “RESET” status

Standard 15.53/EN March 2005 Copyright © 1999--2005 Nortel Networks
Interface signals
The O&M bus is used in the BCF and originates from the CSWM card. Due to itslow rate (9600 bit/s), this bus is not matched.
The O&M bus contains ten logical signals:
from master to slave:
– TX : asynchronous data transmitted by the master
– ADR[5..0 ] : six address lines giving the selected slave address from 00to 63
– VAL : validation pulse, during which the address must be valid(negative pulse)
– RAZ : initialization if this reset is pulsed during VAL pulse,inhibition if the VAL is pulsed during the RAZ (active atlow level)
from slave to master:
– RX : asynchronous data received by the master
Each slave receives from the back--panel six signals, NUC [5..0], that allows it todetermine its address and to compare to the ADR [5..0] address.

3.2 BCF functional architecture
Depending on the BCF physical architecture, the following functions are enabled(see Figure 3--3):
control and switching
data channel concentrator
dual trunk interface
synchronization
alarm regrouping
3.2.1 BCF control, switching and management (CSWM)
3.2.1.1 Functions
The CSWM unit is duplicated for safety reasons, giving CSWMA and CSWMB.
The CSWM unit is the master BCF unit. It enables communication with the BSC,organizes, storesand broadcasts all thedata it receivesfromtheBSC, supervisesanduses defense action on the equipment it controls. It must do the following (seeFigure 3--4 ):
set up communication with the BSC
manage BTS synchronizationmanage the switching matrix
manage the FH bus
manage slave units (DSC, PCMI, ALCO, SYNC, GTW, and the TX part of theTRX). Only the defense actions on slave processors is discussed below.
enable duplex operations
3.2.1.2 Setting up communication with the BSC
When the CSWM is activated, it must connect to the BSC to work. A link is set upon an external PCM. Since a number of PCM links unite the BTS and BSC,individual PCM links are frequently polled. If connection attempts fail on all theavailable PCM, the CSWM resets.
3.2.1.3 Downloading
When the call has been set up with the BSC, the CSWM reports its status. The BSCdownloads the BTS if CSW code has not already been downloaded. The set of theBCF downloadable files is formed by two catalogue files (BOOT & LOAD andDLU), containing the list of the files, a configuration file and a file containingCSWcode.

3.2.1.4 Synchronization management
At start--up, the CSWM chooses the first correct clock from among six. DuringLAPD connection, the BTS forces the clock on the PCM carrying the LAPD.
3.2.1.5 Switching matrix management
The switching matrix management includes the following:
initialization
configuration
monitoring/defense
The switching matrix has 16 PCM links. Each PCM link has the following:
transmission test interface
reception test interface
idle interface
All 2n PCM time slots are connected to 2n+ 1 PCM time slots to allow PCM linksto be routed when the BTS are chained together (drop and insert technique).
Initialization
The 0 time slot on each PCM link is looped back on itself by the transmission testinterface,which isa hardwaredevicethat connects thePCM 0 time slot transmissionand reception on the reception interface.
The frames received and transmitted ineachTS0 overeachPCM link are frequentlycompared to allow the switching matrix to be tested at start--up time and itsperformance to be monitored.
Configuration
The switching matrix is configured when the BSC requests the BCF to set up or
release a signaling or traffic channel.Signaling channels are set up (or broken off) between an DRX signaling time slotand a non--concentrated link on a signaling concentrator unit. This may entail(dis)connection between a concentrated link on a signaling concentrator unit anda PCM link time slot on a PCM interface.
Traffic channels are set up (or broken off) between a DRX traffic time slot and aPCM link time slot on a PCM interface.

Monitoring/defense
The switching matrix is monitored by endless loops that are activated during theinitialization phase.
If a fault occurs, the switching matrix is designated as faulty and switch over istriggered.
The cause can be pinpointed from among the following:switching matrixinternal PCM busidle interface
transmission test interfacereception test interface
3.2.1.6 FH bus management
The FH bus is connected to various DRX or e--DRX or DRX--ND3 units.
Configuration
FH bus management becomes involved when the BSC sends cell configuration orradio transmission configuration messages.
The CSWM uses the cell configuration message to construct the internal tablesneeded for FH bus management.The radio transmission configuration message is used to send monitoring masks totransmitters used to check for frequency collisions and the flags on FH input
Monitoring/defense
FH bus management receives the frequency collision and no FH bus flag messagessent by transmitters on the O&M bus.
Frequency collision messagescause an event report to be sent to the BSC(messagesare correlated to avoid repetition).
No FH bus flag messages result in the following:a DRX or e--DRX or DRX--ND3 fault when all the DRX or e--DRX orDRX--ND3 detect the same eventa DRX or e--DRX or DRX--ND3 fault when one event is detected
3.2.1.7 Transmitter--oriented CSWM defense actions
TheCSWM undertakes defenseactionwhen it receivesalarm messagesor when thescanner no longer detects transmitter activity.
If the faultytransmitter wasconfigured (BCCH), theBTSsends anevent reportwithimpact to the BSC; otherwise, the event report is without impact.

3.2.1.8 DSC--oriented defense actions
The CSWM undertakes defense action when the DSC sends an event report on theO&M bus or when the scanner no longer detects DSC activity.
The following faults can occur:
hardware fault
The DSC is faulty if any of its connections fail. Then the DSC is reset, andexternal tests are run.
unexpected frames or queue overflow
The CSWM sends an event report to the BSC which takes the appropriate action.
loss on the O&M busThe CSWM triggers defense action, the DSC is reset, and external tests are run.
A DSC is initialized by a reset command on the O&M bus. Start--up tests are run.If the external test resultsare fault--free the DSC can bereturned to the list ofuseableunits. If not, the unit must be replaced.
CSWM defense actions are determined in terms of equipment redundancy:
If there is no redundant DSC:• if the DSC that is down supported O&M communication with the BSC. The
CSWM must isolate the faulty DSC by breaking off connections on theswitching matrix. The switching matrix restores communication with theBSC on the same PCM as before. When communication is restored, theCSWM informs the BSC that all communication previously established viathat DSC is lost and cannot be recovered. The BSC then takes the appropriateaction ;
• if the lost DSC did not support O&M communication with the BSC, theCSWM must inform the BSC that all communications passing through thisDSC were lost and cannot be recovered. The next actions are determined bythe BSC.
If a redundant DSC is available, the CSWM breaks off faulty DSC connectionson the switching matrix and reconnects the redundant DSC to match the faultyone. All the communication previously established via that DSC is restored andan event report is sent to the BSC.
3.2.1.9 PCMI--oriented defense actions
In the event of a PCMI hardware fault, the CSWM activates self--tests by sendingthe appropriate commands via the O&M bus. If the results of the self tests arefault--free, the PCMI returns to operational status and the BSC is informed.
If the quality of transmission is the cause, the PCMI feeds back the information tothe BSC, whether it has been able to restore communication or not.

3.2.1.10 ALCO board--oriented defense actions
If there is an ALCO card hardware failure, the CSWM restarts self--tests by meansof the commands available on the O&M bus. If the self--tests are successful, the ALCO card is considered operational again and the BSC is informed.
3.2.1.11 Gateway switchover management
If there is a gateway failure, the gateways themselves determine state change(passive ⇔ active). Then the fault signal is transferred to the CSWM via the O&Mbus.
Eachgateway can send itsstatus to the CSWM, either after a queryfrom the CSWMor spontaneously after switchover.
3.2.1.12 Duplex operation between CSWMs
The duplex function manages CSWM equipment redundancy in the BCF. The BSConly perceives one CSWM at a time.
Redundancy is operated in passive/dynamic mode with hot restart:The standby processor does not execute the same algorithms as the activeprocessor and does not receive the same message flow.The active CSWM sends stable status information to the standby side. If aproblem arises on the active side, the standby CSWM takes over BCF control.Switchover time includes the time needed to locate the fault, return to a stablestatus, and restart processing.
Causes of switchover
Switchover may be triggered by hardware or software resetting. The watchdogtriggers hardware resetting, and software is reset by a software init message.
Hardware resetting may be triggered by the following:a major hardware fault (CPU, memory units, etc.)a serious software fault (address error)
Software resetting may be triggered by the following:a minor hardware fault (switching matrix, internal PCM bus, O&M bus drivers)a system software fault (dynamic memory overfilling)
Switchover procedure
The switchover procedure can only be performed in a stable system status. In theevent of switchover, the CSWM tries to return to the last stable condition. It checksthat its database (last stable state) and slave processor states (alarm units,synchronization units, concentrator units, PCM interface units and transmitterunits) are consistent and may reconfigure them.

Standby CSWM updating
The standby side is brought up to date in the following steps:
asynchronous software downloading
asynchronous data updating
synchronous data updating
The active CSWM side downloads standby CSWM software asynchronously without disturbing operations on the active side.
Asynchronous data updating is performed in the following phases:
The active CSWM instructs the standby CSWM to reinitialize its database.
The active CSWM copies the database and sends it to standby side.
The active CSWM stores status transitions that occur during updating and sendsat the end of the sequence. It then starts synchronous updating.
Synchronous updating is performed each time the BSC sends configuration data or when the CSWM performs defense actions.
The active CSWM sends one or more update messages to the standby side beforesending an acknowledgement or event report to the BSC.
3.2.2 Data Signaling Concentration unit (DSC)The DSC is controlled by the CSWM. It communicates with the CSWM via theO&M bus. It serves channel multiplexing, demultiplexing, and Operations andMaintenance (O&M) functions.
3.2.2.1 Multiplexing and demultiplexing
The CSWM uses the DSC to set up communication between the BSC and the otherentities that make up the BTS. The LAPD protocol ignores the DSC that servesconcentrator and routing functions.
The DSC reads level 2 addresses (TEI) contained in LAPD frames and, using arouting table, sends the information onto another time slot. The time slot may beconcentrated (a number of TEI arrive) or not (single TEI).
3.2.2.2 Operations and Maintenance (O&M) functions
Configuration
The CSWM sends the following to the DSC:
overall configuration
connect and disconnect configurations
8/10/2019 411-9001-063 S8000 BTS Reference
http://slidepdf.com/reader/full/411-9001-063-s8000-bts-reference 444/514
ArchitectureNortel Networks Confidential 3--17
S8000/S8002/S8003/S8006 BTS ReferenceManual
Copyright © 1999--2005 Nortel Networks
Overall configuration data includes the following:
the size of message queues
two queue overflow thresholds
the period defining the moment observation messages are sent
A connection configuration connects a TEI in a single time slot to a secondconcentrated time slot.
Disconnecting may affect a TEI in a single time slot or in a concentrated time slot.
Disconnecting a concentrated time slot automatically triggers disconnection of
the concentrated TEI it contained.
Observations
The DSC returns its status to the CSWM as requested. The status report containsoverload alarms and hardware failures.
The DSC sends regular observation messages to the CSWM that contain thefollowing for the last traffic period and per time slot and TEI:
queue size
the maximum size reached by the queue
number of messages handled since the last status request
Tests
The DSC constantly tests unused time slots. It performs external loop tests onCSWM request.
The results of unused time slot tests are returned to the CSWM in regular statusmessages.
The CSWM may request the DSC to perform external tests. The DSC checks that
links are free and accepts (or refuses) start--up. The DSC returns the results of thesetests as requested.
Monitoring
The DSC supervises its own equipment parts and issues one the following faultmessages:
queue overload
receipt of unexpected frames
PCM link hardware malfunction

Standard 15.53/EN March 2005 Copyright © 1999--2005 Nortel Networks
Fault detection
The DSC receives two threshold values from the CSWM that give the overloadsituation in message transmission queues. When queue thresholds are reached, theDSC issues start and end--of--alarm messages to the CSWM on the O&M bus.
3.2.3 PCM Interface (PCMI)
The PCMI interfaces and synchronizes incoming and outgoing PCM links. Itconverts the external PCM coming from the BSC into internal PCM used by theBSC, and vice versa.
Each PCMI handles one external PCM link. A PCMI unit does the following:
converts external PCM links into internal PCM for BTS use
verifies link quality using error detection codes
matches impedance on the type of PCM link used by the operator
3.2.3.1 Configuration
The PCMI can operate without CSWM involvement. However, the CSWM sendsa configuration message on the O&M bus that contains the following:
thenumber of erroneous seconds, which defines a window used to evaluatePCM
alarmsthreshold M1 for frame alignment error counters
threshold M2 for the CRC error counter
threshold M3 for coding type error counters
3.2.3.2 Monitoring
The PCMI monitors its own equipment and PCM links, and issues fault messagesconcerning hardware alarms or PCM alarms.
3.2.3.3 PCM alarm management
Managing PCM alarm involves frame, multiframe, submultiframe, zero time slot,and frame alignment; CRC is not managed yet.
A frame interval is 125 µs.
The duration of a multiframe is 2 ms, representing the time of 16 frames.
The length of a submultiframe is 1 ms.
TheTS0is set aside for the frame alignmentsignal, multiframealignment bits,CRCbits, and alarm sending.

Frame alignment
Frame alignment is operated by the frame alignment byte occupying the TS0 inevery other frame.
Upon loss of frame alignment the alarm bit is set to 1 and the frame alignmentcounter is increased.
The PCM alarms
Each PCM alarm corresponds to the detection of one anomaly type on the PCMreception.
A seriously erroneous second is a second in which an NOS, SIA, RRA, or LOS
alarm condition occurred or an FE or CRC counter was overrun.These alarms are indicated by LEDs on the front of the DTI board.
LOS: frame lock loss signal (LFA LED)
Frame lock is considered lost when three consecutive lock signals are received with errors. This is also the case when bit 2 of TS 0 in frames that contain nolocking signal is received three times in a row with errors.
AIS: Alarm indication signal (AIS LED). Not used in the GSM 1900 frequencyband.
RRA or RAI: Remote Receive Alarm signal or Remote Alarm Indicator (RRA
LED).NOS: no frame signal (NOS LED)
Upon detecting the beginning of an NOS fault signal, a 64--kbit/s SIA isgenerated on each TS of the associated internal PCM link, an RRA is sent on theexternal PCM link, and the application associates an NOS error to the erroredsecond, bringing on the NOS LED.
FE: Frame error (FE LED).Used in case of 2 Mbit/s external PCM link. Error detection is effected only inoperation without CRC. The application counts the incorrect frame lock words
received, and compares them with the upper and lower thresholds(programmable).SKP: hop indication reception. Not used.
CRC: CRC error signal (CRC LED). Not used in the GSM 1900 frequencyband.The quest for CRC multiframe lock is associated with that for frame lock, toensure that the frame lock word found does indeed correspond to a single lock word to which one can lock permanently.
The alarm LEDs on the front of the board are the LFA, AIS, RRA, NOS, FE, SKP,and CRC. Each alarm event turns on the associated LED for a minimum timeof 200 ms.

One cause is associated with each seriously erroneous second. The alarm cause isdefined in the following descending order of severity: NOS, AIS, LOS, RRA, FE,CRC, and SKP.
When the number of seriously erroneous consecutive seconds reaches the numberof erroneous seconds (NBSEC) defined in the configuration message, the PCM isdesignated in fault condition and a message is sent to the CSW.
The end--of--fault condition is the number NBSEC of consecutive seconds withouterrors and the end--of--fault message is sent to the CSW.
3.2.4 Synchronization (SYNC)
The synchronization unit must synchronize the DRXs on a single reference time,GSM time. It supervises the different defense stages. There are two identicalsynchronization units, that have the same software (see Figure 3--5 ).
Frame alignment
Frame alignment is operated by the frame alignment byte occupying TS0 in everyother frame.
Upon loss of frame alignment, the alarm bit is set to 1 and the frame alignmentcounter is incremented.
The GPRS interface uses asynchronous frame principles in both transmit andreceive direction between PCU and BTS. A Joker channel is used when the size of the frame exceeds the size of the main channel.
3.2.4.1 GSM time
The network supplies the reference time via three PCMI units. The CSWM selectsone of the six clocks and sends it to the synchronization unit. The clock selectedmust have good long--term accuracy because it is used by the synchronizationmodule to generate reference time for the radio interface with an accuracy of
5 x l0--8.If the external reference signal is absent, the CSWM selects a local clock derivedfrom the SYNC module active in “free running” mode.
3.2.4.2 Monitoring
The synchronization unit is monitored by its own control and monitoringmechanisms, which check that the unit is operating correctly and GSM time isavailable on the GSM TIME bus.
Alarms are as follows:

The last two events are fed back to the CSWM. Defense actions are covered insection dedicated to the CSWM.
In case of a synchronization unit fault, the synchronization units make theswitchover decision (active <=> standby). The fault is then fed back to the CSWMover the O&M bus.

3.2.5 Alarm collecting function (ALCO)
3.2.5.1 Functions
The alarm collecting board (ALCO), located outside the BCF, collects internal andexternal BTS alarms.
Internal alarms concern equipment parts on which the BCF does not use anyparticular detection action, while external alarms are site--dependent.
These alarms are sent via the O&M bus to the BCF control unit, which redirectsthem to the BSC.
The board also allows equipment located outside the BTS to be activated (futureuse).
3.2.6 BCF/DRX gateway (GTW)
The gateway (GTW) carries out the following functions (see Figure 3--6 ):
adaptation of the frequency between the radio interface and the Abis interface
adaptation of the GSM TIME bus to the GSM TIME channel
adaptation of the O&M bus to the O&M channel for the TXs
management of the O&M protocol for the gateway as an O&M slavemanagement of part of the defense system
management of part of the switchover logic
initialization of the gateway board
3.2.6.1 Adaptation of the GSM TIME bus to the GSM TIME channel
This function consists in entering the GSM time on the GSM TIME bus, thenmaking calculations and carrying out formating to send the GSM time to the DRXsby means of the GSM TIME channel.
3.2.6.2 Adaptation of the O&M bus to the O&M channel
This function consists in decoding the validation on the O&M bus of a dialoguebetween the CSWM and the TX, and formating the characters sent and received onthe bus and the O&M channel.

3.2.6.3 Management of the O&M protocol
This function provides the level 2 and 3 layers of the O&M protocol concerningCSWM/gateway dialogue. The gateway is fully an O&M slave. It manages alevel--3 message dictionary.
3.2.6.4 Management of the defense
The software part of the gateway defense system essentially concerns detection of minor andmajor faultswhich lead, respectively, to a ”light” software reset of certainfunctions or passage to HALT state. A software watchdog system is also active.
3.2.6.5 Switchover management
The software’s role in switchover management is to send command codes to ahardware logic circuit which controls gateway activation and de--activation.
3.2.6.6 Initialization
Initialization consists of configuring all peripherals present on the gateway board,the communication controllers, the position of the GSM TIME channel, thecross--connect matrix, and the transfer of certain initialization data from the PROMto the RAM.
3.2.6.7 Multitasking organization
Most of the functions are not related to one another and therefore operatecompletely asynchronously. In order for these functions to take placesimultaneously for theexternal environment, an internal function, transparent to theoutside, is needed to manage multitasking, hierarchized organization.
3.2.7 BCF configurations
The BCF exists in simplex or duplex configuration.
The following table gives the number of boards in every configuration.

3.3 CBCF functional architecture
The CBCF performs the following functions:
switching, synchronization, and concentration
control of the alarm management unit
PCM Interface
The CMCF board performs the concentration, synchronization, and switchingfunctions. The CMCF also controls the alarm management unit (the RECAL board), which is located outside the CBCF Module.
The CMCF board allows operation in duplex mode and in simplex mode.The CPCMI board is the interface between the external PCM links (A--bis) and thePrivate PCMs in the CBCF.
CBCF modes
The CBCF can be used in simplex mode with only one CMCF board in slot 0 or 1running in active mode. Simplex/Duplexmode is managed by a microswitch on theCMCF board. From duplex to simplex, the transaction in never automatic, it alwaysfollows a configuration. From simplex to duplex mode, there is no automatic
transition when the active board detects the connection with the passive one.
3.3.1 Switching, synchronization, and concentration
The CMCF board is duplicated in the CBCF Module to provide redundancy (seeFigure 3--7 ).
One CMCF central processor manages the switching matrix and thesynchronization. The main processor and slave processor share the concentrationand routing tasks as described below.
3.3.1.1 Switching
The two switching matrices in the CMCF receive and distribute the traffic of external PCMs as follows:
up to six PCMs communicate with the CPCMI boards
up to six PCMs communicate with the DRXs
two PCMs communicate with the processing units
one PCM to communicate GSM time
one PCM for tests

3.3.1.2 Synchronization
The CMCF provides synchronization to the radio part of the BTS.Synchronizationis obtained through a temperature--controlledoscillator thatallowsthe selection of timing signal from seven signals (six from the external PCMs, onefrom an external source, and one from the CMCF master).
The selected clock signal is routed to a digital phase comparator that authorizessynchronization operations in a frequency locked loop (CMCF master) or in a phaselocked loop (CMCF slave).
The CMCF slave operates in a phase locked loop so that its H4M clock issynchronized with that of the CMCF master. This ensures that phase hopping does
not occur during a CMCF switchover.GSM Time
The processing unit transmits the GSM Time every 60 ms. The GSM Time istransmitted to the switching matrices of the CMCF master. The CMCF slave readsthe GSM Time in the CMCF master, which allows the synchronization of GSMTime on both CMCFs.Figure 3--7 shows the synchronization process on the CMCF board.
Switchover
A switchover occurs in synchronization with the H4M clock. Since the master
CMCF and the slave CMCF are synchronized (H4M and GSM Time), theswitchover does not cause a timing disruption.
The switchover sequence is as follows:active CMCF becomes inactiveinactive CMCF detects the inactivityinactive CMCF becomes active
A CMCF processor becomes inactive in the following circumstances:H16M clock state is NOK and there is dual chain operationthe master request is disabledmaster board is not properly connected to the back panelthe active processor is reset while in dual chain operation
Defence and redundancy management
A switchoverfrom one CMCFboard to the other in the event of an error on the activeCMCF board ensures redundancy. The hardware supports duplex and simplexmodes.
A redundancy channel between both CMCF boards ensures the exchange of databetween the boards in the event of a switchover.
The defense connectivity is shown in Figure 3--8 .

3.3.1.3 Concentration and routing
The concentration and routing functionality is performed by the master and slaveprocessing units. The master processing unit manages the board ressources. Theslave processing unit, which operates synchronously with the master unit, managesone PCM, one HDLC link (for master--slave communication), and one RS232 link.
The master processing unit receives a external clock signal at 4.096 MHz andgeneratesa 33 MHz reference frequency. This frequency issuppliedto theslaveunitso that it can be synchronous with the master unit.
3.3.2 Control of the alarm management unit
The CMCF manages the alarm management unit, the RECAL board, locatedoutside the CBCF Module.
The RECAL board collects internal and external alarms and routes them to theCMCF, which routes to the BSC.
The communication between the CMCF and the RECAL is done using a LAPDprotocol link that uses a channel supported by time slot 25 of PCM0.
3.3.3 PCM Interface
Up to three CPCMI boards provide the interface between six external PCM links
(A--bis) and six Private PCMs used inside the CBCF Module.The interface tasks corresponds to an electrical level translation and a frame formatconversion depending on the type of external PCM link (PCM E1, PCM T1, orHDSL).
The external PCM interface has functional blocs that perform the followingfunctions:
conversion of analog signals on the A--bis interface and the logical signals of theFramer part of the PCMImanagement of the synchronization clock
transposition between the A--bis and the Private PCMs signals
3.3.3.1 Signalling interfaces
The CPCMI board uses the PCM and HDSL interfaces described below.
PCM A--bis interface
The E1 interface is compatible with the G703 Recommendation. Its impedance is120 (two pairs of bidirectional symmetrical links) or 75 Ohms (coaxial cables).
The T1 interface is compatible with ANSI T1.403 and T1.102. Its impedance is100 Ohms (two pairs of bidirectional symmetrical links).

HDSL A--bis interface
The HDSL--E1 format (2B1Q) is on one single twisted copper pair where thetransmission rate is 2320 kbps for a full E1 frame. This rate is compatible with theETSI ETR 152 RTR/TM--06002 standard.
The HDSL--T1 format (2B1Q) is on one single twisted copper pair where thetransmission rate is 1552 kbps for a full T1 frame. This rate is not standardized andis considered a proprietary link.
Private PCMs
One CPCMI board is connected to two Private PCM links (PCM0 and PCM1). TheO&M communication is done through an HDLC link using TS0 of PCM0.
E1/T1
Three bits supplied to the CMCF indicate whether the board is an E1 or T1.

3.4 DRX functional architecture
The DRX board has a digital part, a radio part and a power supply board(Figure 3--9 ).
3.4.1 DRX digital part
The DRX digital part consists of four units:
the Advanced MaNagement Unit (AMNU) which manages the DRX
the Digital Control Unit for eight chanels (DCU8) which is the signal processingunit
the Time Base Unit (BDT) which manages the GSM_TIME for the DRX
TX logic which is the interface with the transmission part in the DRX Radioboard
3.4.1.1 AMNU unit
The AMNU unit manages the DRX. It manages the eight time slots of an TDMA frame, and the radio signaling functions.
These functions can be broken down into communication functions (RSL), on the
one hand, and operating and maintenance functions (O&M), on the other (seeFigure 3--10 ).
Communication functions
Communication functions include:
routing functions
concentration functions
Routing functions
The TDMA frame management unit routes messages from the BSC. The messagesarrive on the RSL and can be broken down into two categories:
messages concerning processing of a single time slot
messages concerning all the time slots in the TDMA frame
Concentration functions
There are two types of messages:
transparent messages
non--transparent messages

Transparent messages are simply concentrated on a time slot of the internal PCM.
Non--transparent messages are:
radio measurement messages of the mobile
interference measurement messages on the inactive channels
load messages on the RACH channel
load messages on the PCH channel
Non--transparent messages are transcoded, averaged and grouped in a singlemessage to the BSC. This message is sent to the same time slot as the transparentmessages.
Operation & Maintenance functions
The following Operation & Maintenance functions are processed by the Framemanagement unit (AMNU):
start--up, downloading, initialization
configuration
monitoring/defense
Start--up/Downloading/Initialization
The AMNU is started by a hardware reset or a reinitialization message sent by theBSC. It causes configuration of the LAPD and establishment of the OML link withthe BSC.
The DRX subsystem can be downloaded only after that the BCF is downloaded andthat the units of site management of cell management and of Abis signaling of theDRXs have been configured.
The BSC systematically initiates a downloading phase of the catalogue files and of the following software units:
AMNUSPU
DLU
BOOT
TX
BDT
BIST of the SPUs
Follows a re--flashing of the units for which the software versions are different.

Configuration
The DRX is configured by the BSC by means of an OML link on the Abis interface.
Configuration can be broken down into:
a general configuration:
• configuration of the TDMA frame
time slot configurations:
• configuration of radio time slots
• configuration of the frequency hop
The Network Identification of the BTS equipment featureconsists in finding a wayto differentiate from a system point of view e--DRX and DRX--ND3 for DRX; ePA and HePA for PA; CMCF phase 1 and CMCF phase 2 Edge featureimplementation.
This feature also allows the addition of new equipment: e--DRX, DRX--ND3, ePA and HePA on sites without any modification of the configRef (DLU).
The DRX--ND3 is designed with the same logical board as the e--DRX.
From a radio point of view, the DRX--ND3 is not able to support edge 8PSK modulation. The DRX--ND3 is not an edge ready hardware.
The DRX--ND3 can be used together with DRX and/or e--DRX.
Configuration of the TDMA frame provides the DRX with parameters shared bythe whole cell, such as:
cell identity (BSIC)
BCCH frequency
indication of frequency hopping implementation
cell type (normal or extended)
and with parameters specific to the DRX:
the frequency of the TDMA frame if there is no frequency hoppingindication of implentation of diversity in reception
The TDMA frame cannot be dynamically configured. A change of configurationrequires re--start of the downloaded software.
The configuration of the radio time slot specifies the type of logical channel to usefor a time slot.
The configuration of the frequency hopping specifies, for a time slot, the list of frequencies to use, as well as sequencing. This configuration is optional and onlyappears if the frequency hopping was requested in the TDMA frame configuration.

Monitoring
The BSC regularly sends status requests to the DRX to detect any problems on theOML link.
LAPD break
The LAPD, OML and RSL linksare monitored by a timer. If level 2 loss is detected,the BSC and the AMNU try to reconnect. If connection has not been made by theend of the time--out, the AMNU is reinitialized.

Event reports
The AMNU collects all events detected by the DRX equipment. It performsfiltration, and error reports to the BSC. Transmission error reports, and faultmanagement on RX--splitters alarms are sent through the BCF or CBCF.
The AMNU filters to prevent repetitionof non--transient events, which means it cansend the BSC a single indication.
The AMNU sends errors to the BSC by sending ”event report” messages. There aretwo types of these messages:
transient messages which are not acknowledged by the BSCnon--transient messageswhich must be acknowledged by the BSCand which arerepeated by AMNU until they are acknowledged.
Radio signaling function
The radio signaling function supports two Signal Processing Units (SPU). EachSPU manages one time slot.
Two versions of the SPU software are available. One corresponds to propagationconditions in rural area and the other to propagation conditions in urban area. Forthe rural areas, the algorithm parameter equals zero where as it is set at the value0.5 for urban areas. In this later case, the interferer cancellation algorithm is active.
The radio signaling functions can be broken down into four groups of functions:level 1 radio accesslevel 2 radio management of LAPDm signalinglevel 3 radio management, which is made up of two functions:• radio resources management• radio measurements managementoperation & maintenance
Level 1 radio access
Level 1 radio access makes it possible to manage dialogue between the AMNUsignaling function and the SPU processors which are connected to the AMNU. Itoffers:
configuration of operating modes for each SPUSPU controltransmission and reception of data on the radio channel, respecting methods forslaving to the radio frequency.
Level 2 radio management
Level 2 radio management manages the LAPDm level 2 signaling on the radiochannels.

Radio resources management (radio level 3)
Radio level 3 provides the following functions:
level 2 management on the common channels
control of level 2 functions on dedicated channels
activation of the common channels
organization of the Common Control CHannel (CCCH), including chaining andrepetition of paging messages and transmission of dedicated channel allocationmessages
activation or deactivation of dedicated channels, implementation of encryption
and channel mode changesproviding SPU processors with system information on the SAACH and BCCHchannels
detection of ”random access” and ”handover access”
detection of paging channel (PCH) load
detection of radio link attenuation (monitoring of the upstream SACCHchannel), verifiable by the OMC
sending of the mobile transmission power change
Radio measurements management (level 3 radio)
This provides the following functions:
return of interference measurements carried out by the SPU processors on theinactive dedicated channels and transmission of these measurements to the AMNU
concatenation of measurements made by the SPUs on the active dedicatedchannels and those transferred by the mobile over the same period
Operation & maintenance functions (O&M)
These functions provide configuration and deconfiguration of the time slots andfrequency hopping functions.
3.4.1.2 DCU8 unit
The DCU8 unit consists of two signaling processing chains, A and B, as shown inFigure 3--11 . Each chain handles four calls in full--rate voice mode and eight callsin half--rate voice mode. Chain A and chain B are connected to a subassembly, theBB_FILT ASIC, which is the interface with the radio part and filters receptionsamples before sending them to the two chains. A second subassembly, the CHIF, which is associated with the BB_FILT ASIC, calculates encryption and decryptionmasks.

The DCU8 unit has five DSPs:
one EGAL DSP, which equalizes the reception signal
two DECOD DSPs, which handle reception signal decoding, and level 1sequencing
two TRANS DSPs, which handle transmission signal processing, encoding, andthe interface with the remote transcoder
There is one DECOD DSP and one TRANS DSP in each chain.
SPU
The SPU carries out processing associated with the transmission layer, and to thisend, it executes a certain number of functions, such as: (see Figure 3--12 andFigure 3--13 ):
demodulation of GMSK signal at reception
ciphering/deciphering of sent and received data
encoding/decoding and interleaving/de--interleaving of data from the variouschannels
encoding/decoding of voice and data (from 13 kbit/s to 16 kbit/s and vice--versa)transfer of discontinuous transmission (DTX) signal
control of transmitters (GSMK--8PSK) and receivers
processing of radio measurements
Demodulation function
Demodulation consists of extracting, from the GMSK signal received, the binarydata transmitted, that is 144 bits for a normal burst and 36 bits for an access burst.This is done for the eight time slots of the radio channel.
The demodulation principle selected takes into account the inter--symbolinterference resulting from smoothing of the transmission phase transitions(limitation of the transmitted spectrum), multiple path phenomena, and distorsionintroduced by the channel filter upon reception.
Implementation of this type of demodulator requires modification of thetransmission channel as concerns pulse response, frequency deviation, andreception times. Determining theseparametersis part of the jobof thedemodulationfunction.

The receiver has the spacediversity function. Both received channels are combinedin an equalizer which carries out joint equalization.For each of these channels, the pulse response as well as the C/I+N ratio areestimated. These ratios are used to weight the predictions and samples of eachchannel.
The symbols from the equalizer are then decrypted, de--interleaved and decoded torestore the control messages and traffic sent by the mobile.
Ciphering/deciphering function
The fluxes of binary symbols sent and received on each time slot on the TCH or
SDCCH are encrypted one bit at a time, in compliance with theciphering/deciphering algorithm.
The ciphering or deciphering operation protects confidentiality of voice andsignaling. It consists of adding binary bits, one by one, between sent and receiveddata and a binary train (the cipheringsequence), generatedfrom a ciphering keyandthe TDMA frame number of the time slot.
Encoding/decoding and interleaving/de--interleaving functions
All traffic and control logic channels are encoded to protect useful informationagainst transmission errors. Each channel has its own encoding scheme, usuallyincluding the following steps for each block:
protection of data bits with parity bits or a block code
encoding of the ”data bits + check bits” unit with a convolutional code; thisoperation gives encoded bits
rearrangement and interleaving of the encoded bits
burst formating
For data, the encoding procedure depends on the rate: the interleaving level ishigher for data than for voice.
Some channels do not use the encoding schemes described above, in particular theRACH, FCCH and SCH channels, for which the notion of interleaving on severaltimes slots does not exist.
Mobile transmission timing advance function
The BTS must measure the delay on the received signal when the mobile stationmakes itself known.
This measurement, knownas timingadvance, is forwarded in the dedicatedchannelassignment message (immediate assignment) to the MS, which uses this parameterto anticipate its transmission timing.

During the call establishment, the BTS computes the timing advance value andsends it within CHANNEL REQUIRED message to the BSC. If this value is abovethe threshold, then the BSC rejects the call establishment.
In ongoing call conditions, the timing advance is calculated at regular intervalsandsent to the MS over the downlink SACCH channel.
The calculation is based on the following:
other measurements taken during demodulation
the timing advance used by the mobile station that is returned in the layer 1header of the uplink SACCH
Discontinuous transmission (DTX)Discontinuous transmission allows signals to be sent over the radio channel alone when a speech signal is present. This limits interference and MS powerconsumption. For each call, the MSC indicates whether the BSS “does not use” or“may use” the DTX.
The principle behind discontinuous transmission is as follows:
The base or mobile vocoder has a Voice Activity Detector (VAD) that detects if theframe constructed every 20 milliseconds contains speech. If the frame does notcontain speech, thevocoder constructs a special frame called the SIlenceDescriptor
(SID) that contains all thebackground noisedescriptionelements. This frame issentto produce a comfort noise at the far end, and radio transmission stops.
The vocoder periodically reassesses the ambient noise and reconstructs the SIDframe. The frame produced in this way is sent in step with the SACCH (once everyfour 26-frame multiframes (480 milliseconds)).
When the vocoder detects new speech activity, a special SID frame indicating theEnd Of Silence (EOS) is sent, and normal speech frame sending resumes.
On the receive end, additional processing sequences interpret the incoming trafficframe types (speech,SID,FACCH, nothing) using therelated flags(BFI, SID, TAF)and perform the appropriate operations.
The DTX is allowed for data in non-transparent mode.
BCCH filling
The BCCH frequency must be transmitted continuously so mobile stations canperform field strength measurements in neighbouring cells.
Continuous transmission is accomplished in the following ways:
When frequency hopping is not used, the TRX uses the BCCH frequency as thecarrier frequency for all the channels it supports. The TRX sends fillers on theBCCH frequency although it may have nothing to send in a given time slot.

When frequency hopping is being used, one of the following occurs:
• Thehopping laws authorizepermanentBCCH transmission, andall theTRXshelp fill operations.
• The hopping laws do not authorize permanent transmission and a transmitteris required to enable BCCH “filling” independently and take over when thehopping laws step down.
Note: That the laws that enables permanent transmission on BCCH are onlyaccepted by cavity coupling.
Transmitter and receiver controlThe SPU controls a transmitter and a receiver. It calculates the frequency hoppinglaw and determines the frequencies to synthesize.
The transmitter is controlled by the FH bus. The SPU sends the following to thetransmitter:
the power and frequency to use
the bits to send
the time synchronization signal
The SPU sends the following to the receiver:the frequency to use for the following time slot
the synchronization clock signal
the GSM TIME synchronization signal
The SPU receives the following from the receiver:
digitized samples from the reception channel
the scale factor (gain)
the receiver alarms
Radio measurement processing
TheRadioMeasurement Processing performedby theBTS ensures that thenetworkandthemobiles can communicate with each other with minimum interference at thelowest possible transmission power and with the best transmission quality.
Measurements processed by the BTS include signal strength andsignal quality. Themobile takes measurements in the downlink direction (BTS --> MS), while the BTStakes them in the uplink direction (MS → BTS). Other measurements include signalstrength on the BCCH frequency of the surrounding cells and the MS_BS distance.

The BTS cyclically sends to the BSC the interferences measures done on theinactive channels.
BB--FILT ASICThe BB_FILT ASIC constitutes the interface between the signal processing unit(SPU) of the DRX and the radio RX module on the one hand, and the enciphering ASIC on the other hand. It carries out the band--pass filtering of the digital samplesoutput by the radio RX module, and generates the FH bus.

3.4.1.3 BDT unit
The BDT (time base) unit regenerates GSM TIME signals. The GSM time isdistributed to the BDT unit of each DRX by means of the GSM TIME channel of the private PCM, every 60 ms.
The value of the propagation delay is sent to the DRX by means of the OML linkof the private PCM. From these two data, each DRX makes the necessarycorrections and regenerates the GSM TIME bus.
If, for any reason, the GSM time is not distributed on the BDT unit, the BDT unitlocally maintains the GSM TIME bus signals and continues to provide the GSMtime to the DRX units.
The BDT unit is made up of a logic block and a calculation block.
Digital block
The BDT unit receivesa 26MHz clock signalderived from the radio unit clock.Thisclock signal has the same stability properties as the 4Fbit clock signal provided bythe BCF synchronization board and is more stable in the short term. The digitalblock generates the following signals:
H4M (4.096 MHz)
STRTM (recurrent pulse at 577 microseconds)
TIME_DATA (containing T1, T2, T3 and TN)
Calculation block
The calculation block synchronizes the H4M and STRTM signals with thesynchronization unit signals of the BCF. In addition, it updates the values T1, T2,T3 and TN.
The synchronization principle consistsof forcing a divider--by--24 counter to divideby 23 (if the BDT is slow) or by 25 (if it is fast). This way, every 23 or 25 periodsof 26 MHz (depending on whether the slow BDT is accelerated or the fast BDT isslowed down), the BDT corrects a period of 26 MHz.
3.4.1.4 TX logic unit
The main role of the TX logic unit is to control the radio subassembly in real time.It receives the BCF configuration commands from the AMNU. It carries out theprocessing and sends back reports.
Once configured, the TX logic unit reads, on each time slot, the data present on theFH bus. Then it calculates the frequency code and the power code to be used withthe radio interface.

Transmission power
In general, radio power is determined by two inputs. One controls the maximumstatic power and the other gives the dynamic attenuation at each time slot.
The static power is given by the BCF or CBCF in the CONFIG message. The TXcalculates attenuation to compensate for cable loss between the TX--driver and thepower amplifier.
The dynamic power is provided by the ASIC of the TX logical unit. Its softwarereads the value and commands the TX--driver accordingly.
In the case of a BCCH filler, the additional attenuation introduced is always zero.
The power values that the TX and the mobile have to use are fixed by the BTSaccording to a control algorithm using the measurements results that it makes andthe thresholds stockpiled in the OMC. The mobile and the BTS power control canbe inhibited by the OMC.
The power control aim is to minimize the interferences, ensure good transmissionquality and save mobile’s batteries.
Power slaving
The setpoint value is slaved to compensate for gain variations of the transmissionchain.
Two slaving loops are used to compensate for attenuation in the gain chain (seeFigure 3--14 ).

These loops may be in the following states:Open: This state isused for calibration of the internal loop with the external loop.Initialization: This state is used for loop start--up.Error: A loop is in error whenit isnot longer in correspondence with the setpoint.Closed: A loop is closed when it is in slow slaved mode.
3.4.2 DRX radio part
The DRX radio part is composed of a power supply board and of the DRX radioboard.
The power supply is converting common -48 V to specific +5 V/ ± 12 V power
supply signals for the DRX radio board.The DRX radio board is composed of three units:
the Frequency reference (Fref) unitthe receiver unit (RX)the transmitter unit (TX)
3.4.2.1 Frequency reference unit
The reference frequency for all local oscillators is derived from the Fref frequencysupplied by the VCXO, itself derived from the 4.096 MHz signal provided by theDRX digital part (BCF or CBCF).
It provides a very steady and spurious--free reference clock for the RX/TX hoppingand fixed synthetizers (13 MHz signal).
3.4.2.2 Receiver unit (RX)
The receiver unit (RX) has four main functions. Slot --to--slot frequency hopping isachieved with a dual synthetizer arrangement (one is active while the other one issetting to the following frequency):
signal down conversion from radio frequency band to Intermediate Frequency(IF) then to base band frequencychannel filtering (in IF)
RX--level dynamic managementdigitization of the base band signal
The base band signal is then sent in binary form with its scale factor to the DRXdigital part. Thereceiver unit isworking aswell onsignal GMSK that signal8--PSK.
Receiver configuration
The receiver configuration is done by the DRX digital part, which sends:the reception frequency to be used for the following time slotthe synchronization clock signalthe GSM time synchronization signal

Receiver monitoring
The receiver monitors internal equipment: microprocessor and Phase Lock Loops(PLL).
If there is a failure or other problem, it generates an alarm:
microprocessor fault
frequency range not respected (if the frequency to synthesize as requested by theDRX digital part is incorrect)
PLL loss of alignment (if one of the receiver PLLs is not aligned)
3.4.2.3 Transmitter unit (TX)
The Transmitter unit has two main parts:
IF and RF chains
gain control loop (or Automatic Level Control)
IF and RF Chain
An I/Q modulator with a Local Oscillator (LO) phase--locked on a referencefrequency transposes the two baseband I/Q signals into the IF chain.
This 125 MHzlocal oscillator (LO_IF) phase--lockedon a 13 MHz signal translatesthe baseband signals into an intermediate frequency. (The IF is 125 MHz inGSM 900, 286 MHz in GSM 1800 and 299 MHz in GSM 1900).
The second LO is used for up conversion from IF to RF.
The up--conversion is followed by bandwidth filter, amplifier stages, variablevoltage attenuators, and digital attenuators.
The Transmitter unit is working as well on GMSK signal that 8--PSK signal.
Gain Control Loop (or Automatic Level Control)
The driver transmit chain upholds the accuracy of the transmission powercompatible with the GSM recommendations against time.
The control dynamics use two components: one voltage variation attenuator (VVA)and a step--by--step digital attenuator taking target attenuation into account andcompensating for it.
The Automatic Level Control also includes the PA.

3.4.3 DRX shutting down
3.4.3.1 DRX soft blocking
The DRX soft blocking consists in setting a DRX “out of service” without stoppingthe calls established on this DRX. If possible, an intra--cell handover is performedfor those calls to release the DRX more quickly. Otherwise, the DRX will bereleased after the normal completion of the calls.
3.4.3.2 DRX soft blocking coupled with a forced handover
To speed up the DRX shutting down, the DRX soft blocking can be coupled witha forced handover. The calls will be handed over a neighbour cell if the signalstrength is over the handover threshold for that cell.
3.4.3.3 Hint
The two actions mentionned above can be performed into a unique command to abetter efficiency of the DRX shutting down.
3.4.4 Power supply board
The power supply card provides a dc voltage between 40.5 V and 57 V, to beconverted into +5 V, +12 V and --12 V. The 48 V voltage is sent first to the logicalDRX unit converter, then, after filtering, to the logical DRX unit and the radio DRXunit converter.
The power supply of the board varies according to the DRX types and on thefrequencies.
The mechanical and electrical grounds are linked to the common reference zerovolts.

Synchronization management
At the start--up, the BTS selects the clock. During LAPD connection, the BTSforces the clock onto the PCM carrying the LAPD.
Switching matrix management
Each PCM link managed by the switching matrix has a transmission testinterface, reception test interface, and an idle interface
The switching matrix is configured when the BSC requests to set up or to releasea signaling or traffic channel from the BTS.
Signaling channels are set up (or broken) between a transmission signaling TS
and a non--concentrated link. This operation mayentail (dis)connection betweena a concentrated link TS coming from the BTS and a PCM link TS on the PCMinterface.
Traffic channels are set up (or broken) between a transmission traffic TS and aPCM link TS on the PCM interface.
Data signaling concentration function
The BTS usesthis function toset upthe communication between the BSC and theother entities that make up the BTS. This function is implemented with theLAPD protocol that serves concentrator and routing functions.
Time base
The time base regenerates the GSM_TIME bus with information issued from theGSM_TIME channel.
If, for any reason, the GSM time is not distributed to the time base, this onemaintains the GSM_TIME bus signals locally and continues to provide the GSMtime to the logic unit.
Synchronization function
The synchronization function must synchronize the transmissions on a singlereference time: GSM _TIME.
The network provides a radio reference clock via two PCM links. This clockselected has good long--term accuracy. It’s the reason that the synchronizationmodule to generate an exact reference time for the radio interface uses this clock..
If the external reference signal is missing, the BTS selects the local clock.
The synchronization function is monitored by internal control and monitoringmechanisms.They checkthat thesynchronization is operatingcorrectlyand that theGSM time is available on the GSM_TIME bus.

AMNU
The AMNU (Advanced MaNagement Unit) monitors site and transmissions andmanages the eight time slots of a TDMA frame.
The following functions are processed by the frame management unit (AMNU):
start--up, downloading, initialization
configuration
monitoring
LAPD break
event reports
Start--up, downloading, initialization
The AMNU is started by a hardware reset or a re--initialization message sent by theBTS. It configures the LAPD and establishes an OML link with the BSC.
Depending on the BSC request, the BTS systematically initiates a downloadingphase of the catalogue files and the following software units:
boot software and operating system: BOOT
TRX monitoring and maintenance software: OML AMNU
site monitoring and maintenance software: BCFtest software: TOOLS
TDMA1 & TDMA2 radio signaling link managementsoftware: RSL1 & RSL2
hardware configuration DLU: DLU
A reflashing of the units for which the software versions are different follows thedownloading.
Configuration
The transmission is configured by the BSC via the BTS.
The configuration provides:
a general configuration. It contains the configuration of the TDMA frame andprovides the logic unit parameters shared by the whole cell, such as:
• cell to identity (BSIC)
• BCCH frequency
• indication of frequency hop implementation
• the frequency of the TDMA frame if there is no frequency hopping

a configuration of the radio TS. It specifies the logic channel type to use for TS.
a configuration of the frequency hop. It specifies, for TS, the listof frequenciestouse, as well as sequencing. This configuration is optional and only appears if thefrequency hop was requested in the TDMA frame configuration.
Supervision
The BTS regularly sends status requests to detect any problems.
LAPD break
A timer monitors the LAPD with the OML and RSL links. If level two loss is
detected, the BSC and the AMNU try to reconnect. If connection is notre--established before the end of the time--out, the AMNU is reinitialized.
Event reports
The AMNU:
collects all events detected (internal or external alarms)
provides the filtration and reports errors (transmission/reception) to the BSC
provides thefiltration to prevent repetitionof non--transient events, whichmeansit can send to the BSC a single indication
The AMNU sends errors to the BSC by sending ”event report” messages throughthe BTS. There are two types of these messages:
transient messages which are not acknowledged by the BSC
non--transient messageswhich must be acknowledged by the BSCandwhich arerepeated by AMNU until they are acknowledged

4.2 BTS software functions
BTS software is distributed among three major units (see Figure 4--1 andFigure 4--2 ):
The DRX or e--DRX or DRX--ND3 unit is designed to transmit and receive(modulate and demodulate) and manage TDMA frames on the radio channel.
The CBCF and BCF manage their slave units:
• CBCF: CPCMI, RECAL, DRX or e--DRX or DRX--ND3, CC8
• BCF: ALCO, DSC, DRX or e--DRX or DRX--ND3 Interface, PCMI, Tx, andSYNC
The TIL unit is used for in--factory testing of the BTS, and to configure, control,and supervise the BTS on site.
The following terms are used in this chapter:
BIST: Basic hardware self--test programs of a BTS subsystem subassembly.These tests validate a subassembly intrinsically, without disturbing the othersubassemblies. An example is the AMNU BIST, which tests the components(such as memory) of the AMNU unit on the DRX or e--DRX or DRX--ND3logical board.
Self--tests: Global, functional test programs, which use several subassemblies inorder to validatean assembly (such as the DRXor e--DRXor DRX--ND3). Thesetests can be broken down into tests of more or less elementary functions. Thismay require external equipment (so the term may be misleading).
Downloading: A process which consists of installing, in the DRX or e--DRX orDRX--ND3 (logical part), software from an external entity (terminal, Ethernetnetwork, BSC, etc.).
Loading: A process used to load, into thesubassembliesof theDRXor e--DRXorDRX--ND3 (logical part), the software it requires for its nominal operation.
The Network Identification of BTS equipment feature consists of finding a way todifferentiate froma system point of view e--DRXandDRX--ND3for DRX; ePA andHePA for PA; CMCF phase 1 and CMCF phase 2 Edge feature implementation.
In addition, this feature adds new equipment: e--DRX, DRX--ND3, ePA and HePA on sites without any modification of the configRef (DLU).
The DRX--ND3 is designed with the same logical board as the e--DRX.
From a radio point of view, the DRX--ND3 is not able to support edge 8PSK modulation. The DRX--ND3 is not an edge ready hardware.
The DRX--ND3 can be used together with DRX and/or e--DRX.

4.2.3.1 PCM Management
This function selects one of the incoming PCMs for communication with the BSC.It then routes PCM TSs to the appropriate equipment in the BTS as the BSCrequests. Other PCM TSs are routed toward another PCM to allow drop & insertfunctionality.
This function also ensures LAPD concentration.
Secured loop function
Secured loopfunction isan enhancement of Drop & Insert mode. In case of networktransmission failure (PCM or Optical Fibre or Microwave links, HDSL modems...)
in BTS loop, secured loop feature ensures that the ongoing calls are maintained,signalling links are maintained and automatically switched over on the redundantpath.
Secured loop function is based on:
duplicated BSC PCM interfaces (thanks to E1 SLTI boards),
duplicated BTS CPCMI boards,
duplicated BTS CMCF boards (with S4 commissioning switch in the “ON”position on both passive and active CMCF boards, and with dedicated SecuredLoop CBCF software),
duplicated PCM links through the transmission network (loop with one PCMonly),
a dedicated 64 Kbit/s TS (TS 31), called Shared Time Slot (STS), on each PCMlink.
The selection of the active path is performed via a dedicated protocol carried on theSTS.
4.2.3.2 Configuration and supervision management
This function translates the OML A--bis model into a physical model to offer astandardized configurationandsupervision to the BSC. TheCBCF acts as an A--bisfront end toward the BSC for configuration and supervision purposes. It is the onlylink for configuration messages coming from the BSC. The CBCF uses theCBCF/DRX or e--DRX or DRX--ND3 protocol to drive any actions concerning theDRX or e--DRX or DRX--ND3.
4.2.3.3 Software management
The CBCF performs software management for the BTS and provides the only linkfor downloading messages from the BSC. When a RECAL or CPCMI board isdownloaded, the CBCF/Slave protocol is used.
