1 System Module operation and main blocks

1.1 OperationFlexi Multiradio BTS System Module hosts the telecom control, system operation and

maintenance, baseband application, transmission, and power distribution functionality.

The System Module can also act as a System Extension Module operating in a

baseband extension mode (future software feature candidate).

Flexi Multiradio System Module hardware supports the following software operating

modes:

• WCDMA dedicated mode

• LTE dedicated mode

It has multiband support, i.e. RF Modules for different frequency bands can be con-

nected to the same System Module.

The following versions of Flexi Multiradio BTS System Module are available:

• System Module FSME

The System Module provides the following BTS external interfaces:

• BTS Site Manager

• transmission interfaces

• four external interfaces towards RF

• site support system interface (for example, battery back-up)

• auxiliarity interface (customer-specific Ethernet port with overvoltage protection)

• auxiliarity interface Ethernet for future expansions

• external alarms and controls interface (customer-specific alarms)

• external synchronisation input interface

• external synchronisation output interface

• baseband extension interface

The System Module has an integrated BTS clock that distributes the synchronisation

clocks to other BTS modules.

The System Module uses nominal -48 V DC and distributes it on to RF and System

Extension Modules. The System Module includes integrated fans.

The System Module can be used, for example, for the following software functionalities:

•

BTS level O&M processing (BTSOM) • resource management

• node B server

• NBAP handler

• user plane management

See the following figure for an exploded view of the System Module.

Figure 3 Functional blocks of the System Module (FSMD/E)

Flexi Multiradio BTS control and multiplexing

This functionality is responsible for BTS control and management, system clock gener-

ation and distribution to other modules and sub-modules. The functional distribution of

this functionality is as follows:

• Control MCU and clock generation: This includes the NBAP termination, telecom

and overall BTS control functionality, system O&M functionality, external site

support system and other equipment control. It generates system reference clock

and frequency reference for synchronising with other BTS.

• External interface block: This block facilitates the external interface for external

equipment control.

• Summing and multiplexing functionality: This functional block is used for data routing

between the radio modules and the baseband.

• RF Module interface: This logical functional block is responsible for providing out-

put/input interface to or from a maximum of three RF Modules.

• Baseband extension interface: This logical functional block is responsible for provid-

ing output/input interface to or from the System Extension Module.

Flexi Multiradio BTS transmission sub-module (FTxx)

The transmission sub-module supports the following functionalities:

• ATM over E1/T1/JT1

• ATM over STM-1

• ATM over Ethernet

• Inverse Multiplexing ATM (IMA)

• Synchronisation

• Iu-PS Control Plane and Iu-PS User Plane

• Iur Control Plane and Iur User Plane

• IP functionalities (DHCP, routing, NTP, packet filtering)

• Transport performance counters

Different variants of the transmission sub-module in the System Module are supported

in order to provide different interface types in the Flexi Multiradio BTS. Transmission

sub-modules available for LTE as presented in the following table.

and transmission sub-modules

2.1 Power requirements of the System Module

The power supply of the System Module is described in the tables below. The same

power consumption figures also apply for the System Extension Module.

* During cold start-up (module heating on, high load)

** Operational power consumption at room temperature

*** Module in idle state, fans off, +0°C

All above with nominal 48V voltage input.

For the fuse ratings of the FPFB outputs, see section FPFB interfaces below.

For transmission sub-module power consumption figures, see section Power require-

ments of transmission sub-modules.

2.2 Power requirements of transmission sub-modules

The typical power consumption of the transmission sub-modules is described in thetable below.

2.3 FPFB interfaces

Power is distributed from Flexi Power Distribution and Fuses (FPFB) to the System

Module.

The FPFB does not have any circuit breakers but instead electrical fuses and a dedi-

cated power switch for the System Module. The fuse rates for the FPFB are:

• RF1-3 31.0A (+/-2A), EXT 25.0A (+/- 4.5A)

See the following figure for the location of the FPFB.

Figure 5 Location of the FPFB in the System Module

Inputs and outputs

A busbar input connector (with screw connection) must always be used for input con-

nections of the FPFB and when connecting power to the System Extension Module.The multibeam connectors on the front panel must not be used as input to the FPFB.

The multibeam connectors are not hot-plug connectors. The power must be switched off

via the on/off switch on the FPFB front panel when connecting or disconnecting the RF

or System Extension Module to the FPFB.

5 System Module LED indicationsThe System Module has seven tri-colour LEDs on the front panel to indicate the opera-

tional status of the module and all fault conditions during operation. See the following

figure for the System Module LEDs.

6.2 External synchronisation output interface connector pin

map

Figure 11 MDR14 connector

The Sync out connector pin map is presented in the following table.

Signal descriptions:

• 2M_out: 2.048 MHz clock reference output (ITU-T G.703/chapter 13)

• The signal comes from the Flexi transport part.

• The signal in MDR14 is asymmetric: connect the core of the coaxial cable to pin

7 and cable shield to GND (e.g. pin 14).

• Testclk_out: 10MHz system clock (LVTTL)

• The signal comes from BTS OCXO which is used for air I/F generation => refer-

ence for the RF measurement equipment.

• Note: the BTS OCXO is not in the PLL mode, the locking is very loose due to air

I/F stability reasons.

• The signal in MDR14 is asymmetric: connect the core of the coaxial cable to pin

11 and cable shield to GND (e.g. pin 10)

• GND: signal ground, for asymmetric signals

• PPS_out: Pulse Per Second (1Hz) frequency and time reference (electrically RS-

485)

• GPStime_out: GPS time reference (electrically RS-485)
