WARNING!

r DO NOT remove or insert theTransmitter Unit with DC power on.

r Power to the OutDoor Unit (ODU) is carried onthe coaxial cable between the InDoor Unit(IDU) and the ODU. Before connecting orremoving the cable, ensure that the primarypower to the IDU has been switched off.

WARNING!

This equipment contains components which aresensitive to "ESD" (Electro Static Discharge).

It is therefore essential that whenever disassem-bling the equipment and/or handling PCboards, special precautions to avoid ESD haveto be made.

These precautions include personnel ground-ing, grounding of work bench, grounding oftools and instruments as well as transport andstorage in special antistatic bags and boxes.

IEC82 5-2: 1993

CAUTION!

The Optical Interface must only be serviced byqualified personnel, who are aware of thehazards involved to repair Laser products.

When handling Laser products the followingprecautions must be taken:

r Never look directly into an open connectoror optical cable

r Before disconnecting an optical cable, thepower should be switched off. If this is notpossible, the cable must be disconnectedfrom the STM-1 output before it is discon-nected from the STM-1 input.

r When the cable is reconnected it must beconnected to the STM-1 input before it isconnected to the STM-1 output.

CAUTION!Exposure to strong high frequency electromag-netic fields may cause thermal damage topersonnel . The eye (Cornea and lens) is easilyexposed.

Any unnecessary exposure is undesirable andshould be avoided.

In Radio-Relay communication installations,orderly setup for normal operation, the generalRF radiation level will be well below the safetylimit.

In the antennas and directly in front of them theRF intensity normally will exceed the dangerlevel, within limited portions of space.

Dangerous radiation may be found in theneighbourhood of open waveguide flanges orhorns where the power is radiated into space.

To avoid dangerous radiation the followingprecautions must be taken:

r During work within and close to the frontof the antenna; make sure that transmitterswill remain turned off.

r Before opening coaxial - or waveguideconnectors carrying RF power, turn offtransmitters.

r Consider any incidentally open RFconnector as carrying power, untilotherwise proved. Do not look into coaxialconnectors at closer than reading distance(30 cm). Do not look into an open wave-guide unless you are absolutely sure thatthe power is turned off.

Use of controls or adjustments or perform-ance of procedures other than those specifiedherein may result in hazardous radiationexposure .

2.0 IDU Description

Fig. I-1 IDU Front Layout

Figure I-1 shows the IDU front layout. All the connectors are located on thefront for easy operation. In addition to the STM-1 data interface, 2Mbit/swayside and 64kbit/s data channels are available. The IDU is equipped withan integrated supervisory system for local and remote configuration andcontrol. The supervisory system communicates with the ODU by use of anFSK modulated channel on the coaxial cable. The same coaxial cable alsocarries power to the ODU. An integrated 2 lines LCD is available for alarmview and RF input and output level monitoring (see Section V; TroubleShooting). For configuration and management purposes the IDU is equippedwith two LCT interfaces for connection to the PC, one with RS-232 interfaceand one LAN TP interface. In addition NI interfaces for connection to otherIDU’s or other Nera equipment are provided. The IDU has a connector foralarm input/output functionality (ALM & AUX).

Figure I-2 shows a block schematic view of the IDU with STM-1 NetworkNode Interface. In radio transmit direction the STM-1 input is CMI decodedand fed to the SORP ASIC. It performs all the SOH processing and radioscrambling. The FIR ASIC encodes the signal by use of a convolution codeand maps it to the 32CROSS constellation. It also performs the necessarypulse shaping. The signal is then I/Q modulated, and the 350MHz IF signalis fed to the ODU interface and applied to the IF coaxial connector. In radioreceive direction the 140MHz IF from the ODU will interface the IDU on thesame connector. The necessary equalising functions are provided in theODU interface before the IF signal is presented to the coherent demodulator.From the demodulator the signal is fed to the adaptive time domain equaliser.The equalised signal is then decoded in the TRELLIS decoder, by use of softdecision and the Viterbi algorithm for error correction. The signal then goesto the SORP for radio descrambling and SOH processing, and is finally CMIencoded in the CMI interface.

3.0 ODU DescriptionThe ODU is an assembly of branching unit and transceiver unit. The ODUis connected to the IDU with a single coaxial cable. The coaxial cable providesTx-IF, Rx-IF, signalling and power supply. For flexibility and easy installa-tion, the coaxial cable is connected to the transceiver through the branchingunit. The transceiver is attached to the branching with a snap on system.With this solution, the coaxial cable may remain connected during transceiv-er replacement. The ODU and the antenna are assembled very closelytogether making it very compact. Nevertheless the antenna can be separatedfrom the ODU by use of a flexible waveguide.

The branching unit contains RF channel filters, circulators and overvoltage-protection.

The transceiver unit contains a microwave Tx/Rx module, a synthesised localoscillator and a transceiver main board, all in a waterproof housing. Thetransceiver is based on dual frequency conversion in the transmitter andtriple conversion in the receiver. This radio architecture with high IFfrequencies allows for use of wide band branching filters while still maintain-ing excellent spectrum purity in transmitter and high selectivity in receiver.The use of wide band branching filters allows for a wide choice of remotechannel frequency selection without changing hardware.

The microwave module is an integrated multi-chip module with GaAs HEMTMMICs for Power Amplifier and Low Noise Amplifier. The necessary LOfrequencies for the frequency converters are generated in a low phase noisesynthesiser unit. The channel frequency is remotely programmed from theindoor unit. Transmit/receive IF-chain, control-circuits, signalling andpower supply are integrated on the transceiver main board.

4.0 ManagementAn integrated supervision system makes the CityLink capable of function-ing as a Network Element (NE) in a managed SDH transmission network.Management and supervision of the CityLink can be performed in variousways from very simple alarm monitoring to standardised managementthrough optional built-in NE agents. Standardised use of Q

ECC, according

to ITU-T Rec. G.784, is provided.

The CityLink also supports embedded SNMP agent that can be controlledby SNMP based manager supplied by the service provider.

For element and network management the NEW-NMS (Nera Element vieW- Network Management System) software provides the full range of manage-ment functionality; Fault, Performance, Security and Configuration.

The integrated SNMP agent provides interface to higher level NetworkManagement Systems.

The alternative interfaces available at the IDU are described in Appendix I;IDU Interface Description.

5.0 Hot StandbyIn Hot Standby configuration, the IDU, the transceiver unit and the coaxialcable between IDU and ODU are duplicated. The two transceivers share acommon branching unit. A switch and a hybrid at radio frequency, includedin the branching unit, allow for switching between the two transmitters andprovides signal to the two receivers respectively. An IDU-switch unit isplaced between the two IDUs. Figure I-4 shows the IDU switch front layout.

The following user interfaces are protected in hot standby configuration:• STM-1 interface• 2 Mbit/s wayside interface• 2 MHz synchronisation interface

When power is applied to the IDU the system will perform self test, this willtake a few seconds. The message “* PWR On Boot * Please wait...” will bedisplayed on the LCD during the test period. If no fatal errors are found theactive SW version will start. The message “Starting Application” will bedisplayed for a few seconds while the application SW is starting.

Error messages and how to correct them are described in Section V TroubleShooting.

2.1 NEW-NMS/NEW-Configurator Startup andconnecting to Network ElementsThe NEW-NMS/NEW-Configurator (Nera Element vieW-Network Manage-ment System/ -Configurator) program must be installed on a PC satisfyingthe requirements depicted in the program manual. Follow carefully theprogram installation instructions to make sure the program is successfullyinstalled.

The element viewer can monitor the network elements using a serial connec-tion (RS-232) or a TCP/IP connection (or both for different network elements).Apply all external connections to the PC before the program is started.

A serial connection must be used the first time the network manager/configurator is connected to the CityLink, because the IP address must beset in the CityLink, before a TCP/IP connection can be established.

2.1.1 Starting NEW-NMS/NEW-Configurator withSerial Connection (RS-232/ LCT).Apply the serial cable to one of the serial ports of the PC and the LCT portof the CityLink.

Start the program. A Log on dialog box pops up. Log on to the network withyour user id and password. The program has an auto discover function whichautomatically discovers network elements connected to the serial ports ofthe PC when starting. If some network elements are connected to the serialports of the PC, the network topology is automatically discovered and

presented in the Explorer view. Press Add to include discovered elements inthe network topology of the program. The auto discover function can alsobe manually executed by selecting Discover from the File menu. Whendiscovering the network manually the program looks for network elementsat the open ports listed in the Communication dialog box (select Communi-cation from the Configuration menu).

2.1.2 Starting NEW-NMS/NEW-Configurator withTCP/IP Connection.(Assumes the TCP/IP address is configured in the CityLink )

Apply Ethernet connections to both the CityLink and PC. Start the program.A Log on dialog box pops up. Log on to the network with your user id andpassword. The program does not know the IP-address of the networkelement so the connection must be manually established. To configure aTCP/IP connection to the network element, select Communication from theConfiguration menu. Press the Add button and type the IP address of the NEin the address field of the dialog box which pops up. Press OK to save thechanges, and OK to close the Communication Configuration dialog box.Select Discover from the File menu. Press Add to include discovered elementsin the network topology of the program. The accepted network elements willbe discovered and presented in the Explorer view.

2.2 Initial configurationWhen the program has established contact with the CityLink, some config-urations must be set before antenna alignment can be performed.

A Configuration Wizard will guide you through the initial configurations.Start the Wizard by selecting the network element in the Explorer view. Thenselect Configuration > Wizard from the right mousebutton context menu.Follow the Wizard instructions.

All the configuration settings are described in Section IV; Configuration.

You are now ready to proceed with antenna alignment.

The purpose of the alignment procedure is to obtain maximum signal leveland cross polarization discrimination by aligning two antennas in oppositedirections.

The antennas should be properly mounted and polarized in the same way.It must be possible to transmit from one antenna and receive on the other.The best way is to have a transmitter and a receiver connected to both antennas.

3.1 Procedure for Coarse-alignmentAdjust both antennas to correct directions as precisely as possible by usingmagnetic compass or optical sight.

3.2 Procedure for Fine-alignmentFine adjustment is achieved by sending a signal from one of the antennas.On the receive side various methods may be used.

a) Measure the AGC voltage from the transceiverb) Read the received level on a spectrum analyzerc) Measure the received power with a Power Meterd) Use the audio signal to adjust for maximum input power. The audio

signal is activated by removing the cap from the AGC connector.

Mute the transmitter at the receive station to exclude interference from thissource.

It is recommended that the person adjusting the antenna can read theinstrument while adjusting. It is very easy to be misled if the signal is fading.

If the AGC voltage is used, a voltmeter should be connected and monitoredby the person who is adjusting the antenna. Adjust alternatively in azimuthand elevation till the received signal is at maximum level. Try a few times ineach direction.

The antenna should be turned enough that the first sidelobes are seen,thereby ensuring that the antenna is aligned on the main lobe.

When the antenna is correctly adjusted, secure all bolts. Monitor theinstrument during this operation and if necessary realign the antenna.

When adjustments are completed on the first antenna, this should be usedfor transmitting while the same procedure is performed on the oppositeantenna.

3.3 Cross Polarization AdjustmentAfter alignment of the antenna, the antenna feed should be adjustedhorizontally and vertically. Loosen the flange which secures the feed to thereflector. Align the feed by using a spirit level. Secure the flange.

3.4 Final ControlWhen all adjustments are performed check that the input level agrees withthe one theoretically calculated. If the input level is too low, adjust theantennas once more. Finally, ensure that all bolts and nuts are properlymounted and secured.

3.2 Alarm Indication Signal Insert(For advanced users)The Path Trace functionality and the AIS (Alarm Indicator Signal) function-ality are used for verifying that the received STM-1 frames are the frames wewant to receive (correct routing, frequency alignment...). This is done byeither inserting a fixed byte or a user defined ASCII string in the J0 slot in theRSOH, or a two bit RF ID symbol at the transmit end. This is done from thepath trace sheet. The RF ID functionality is only available at the Radio side.The radio that receives the STM-1 frames must have the same Trace string(J0) or RF ID defined in the AIS insert sheet. If there is a mismatch, an AIScan be inserted. An AIS can also be inserted if the HBER threshold isexceeded.

The AIS Insert configuration sheet can be opened from the Configurationcontext menu of both the Transmission Radio and Line Rx nodes in theExplorer view. The sheet can also be invoked by selecting (highlighting) oneof the Transmission Radio and Line Rx nodes in the Explorer view and thenselecting Edit AIS Insert from the Configuration menu.

Figure IV-12 Routing Table Configuration Sheet

4.0 Equipment Node

4.1 Network RoutingEvery CityLink Network Element has a static and a dynamic routing tablewhich relates incoming messages, addressed to other NEs, to different ports.The NE evolves a Dynamic Routing Table, while the Static Routing Table isset by the user.

The dynamic routing table evolves towards the optimal routing table. Whenthe NE is reset, the dynamic routing table is reset too, so when the NE is turnedon again the NE has to evolve the routing table from “scratch”.

The static routing table is only used after the IDU has been booted. It is usedas a starting point for the dynamic routing mechanism, and will thus, ifproperly set, decrease the time the NE uses to create a sufficient routing table.Static entries can be manually added and dynamic entries can be copied tothe static table.

The Routing Table configuration sheet can be opened from the Configura-tion context menu of the Equipment node in the Explorer view. The sheet canalso be invoked by selecting (highlighting) the Equipment node in theExplorer view and then selecting Edit Routing Table from the Configura-tion menu.

5.4 Switching CriteriaThe Hot Standby system operates in two modes, manual and automatic.In manual mode the Rx-switch and the Tx-switch are controlled by NEW. Noalarms in the system will cause the system to switch. The system is switchingthe Rx-switch and the Tx-switch at the same time (bidirectional).In automatic mode the switching is based on alarms in the system. Inautomatic mode the Rx-switch and Tx-switch can operate either bidirectionalor unidirectional.

Unidirectional mode: The system will only switch the transmission directionwhere the alarm has occured.

Bidirectional mode: The system will switch in both directions when an alarmoccurs. The traffic will go through the same IDU and ODU in both directions.Hence, the other IDU or ODU can be removed without disturbing traffic.Exception: When an alarm occurs in IDU-A, the system tries to switch to IDU-B/ODU-B. If ODU-Bis not able to take over the traffic, the system will thentry to keep the traffic running by only switching to IDU-B and continue usingODU-A. The system has switched to unidirectional mode to try to keep thetraffic running. The system will resume bidirectional mode next time an alarmoccurs.

Switching criteria in receive direction:• RF-INPUT The RF input signal is missing (ODU)• LO Local oscillator alarm (ODU)• IF-DEM Loss of incoming 140MHz IF to demodulator (IDU)• LOF Loss of frame (i.e. sync loss in demodulator) (IDU)• HBER User defined bit error threshold.• LT-PLL Line Transmit PLL alarm (IDU)• ACCESSORY

CONTROL Cable removed between IDU and IDUSwitch• Loss of comunications between IDU and IDU-Switch for more then

30 s.

Switching criteria in transmit direction:• RF-OUT RF output power alarm (ODU)• LO Local oscillator alarm (ODU)• IF-INP Loss of 350 MHz IF input to transceiver (ODU)• IF-MOD Loss of IF output from modulator (IDU)• LOF-LR Loss of frame at STM-1 input signal to IDU• LOS-LR Loss of STM-1 input signal to IDU• RT-PLL Radio Transmit PLL alarm (IDU)• TRELLIS PLL Trellis coder out of lock

3.0 Troubleshooting by NEW-NMS Configurator

3.1 IntroductionFault management is the process of locating and correcting network prob-lems or faults. Fault management is possibly the most important task innetwork management. It consists of identifying the occurrence of a fault,isolating the cause of the fault and correcting it if possible. The faultmanagement increases the network reliability by giving the network operatora tool that quickly detects problems and initiates recovery procedures.

NEW contains functions for acquisition, presentation and storage of alarmsand events from the network to be managed.

3.2 Information AcquisitionIn order to detect faults, information must be gathered from the network. Thestate of the network is monitored using two different methods.

3.2.1 PollingThe various network elements should be polled on a regular basis, so thatchanges in Network Elements (NE) are detected and network connectivityis checked. Which NE to poll, the polling rate and what to be polled for aspecific NE is user definable.

3.2.2 Event NotificationIn addition to polling, some NEs have the ability to spontaneously reportevents. The NEW will gather this information in addition to polling. Thisfeature will decrease the managers response time to network events consid-erably.

3.3 Alarm PresentationIn all views, where network information is presented, colors are used toindicate the alarm severity status of the network elements. To easily identifythe status of the network elements, all alarms are classified according to theirseverity. Each alarm severity class has a color. In the different views, thenetwork elements change colors according to the color of their most severealarm. The alarm classifications are described in the table below.

Severity Colour Description(default)

Normal Green No alarms or warning have been reported fromthe network element

Warning Yellow Indicates the detection of a potential orimpending service-affecting fault, before anysignificant affects have been felt. Action shouldbe taken to further diagnose and correct theproblem in order to prevent it from becoming amore serious service-affecting fault.

Minor alarm Dark Yellow Indicates the existence of a non-service-affecting fault condition and that correctiveaction should be taken in order to prevent amore serious fault.

Major alarm Orange Signifies that a service-affecting conditionhas occurred and urgent corrective action isrequired.

Critical alarm Red The most severe alarm. It signifies that aservice-affecting condition has occurred andan immediate corrective action is required.

No contact Blue Indicates that no contact is achieved with thenetwork element. The communication settingsshould be checked in order to obtain contactwith the element.

Misconfigured Magenta The network element has not been properlyconfigured.

3.4 Visual Alarm NotificationThere are four different ways of monitoring alarms in NEW. These methodsare described in the following subchapters. The NEW context sensitive helpsystem offers a more comprehensive support on all features in the NEWprogram.

3.4.1 Alarms on a Tree node/leaf in the Explorer viewThe Explorer View is opened by selecting Explore Net from the View Menu.Figure V-5 shows an example of the Explorer view.

The Explorer View shows the Network information in a logical manner. EachNE is divided into two main branches; A Transmission branch and anEquipment branch. The sub-branches and leaves under the Transmissionsbranch concern the transmission aspects of the NE. The sub-branches andleaves under the Equipment branch concern the physical equipment of theNE.

Figure V-5 Example of Explorer View

The Explorer view use the severity colours to indicate alarm events. Thealarms are presented in a hierarchical manner. The colour of the most severealarm is inherited from the leaf where the alarm was identified, to all branchleaves up to the section symbol. E.g. the section and NE symbols will alwaysshow the alarm colour of the most severe alarm identified in the sub-branchesin the Explorer view.

By pressing the right mouse button on any nodes/leaves in the Explorer Viewand selecting Current Alarms from the context menu, a Current Alarm List(ref. Appendix III) is opened showing all alarms Hierarchical below theselected leaf.

3.4.2 Alarms on a Node symbol in the Map viewThe Map View is opened by selecting Map Navigator from the View Menu.Follow the instructions in the Help file to create a map. Figure V-6 shows anexample of the view.

The Map View shows the Network information in a physical manner. EachNE is showed as an NE icon. Graphic-files can be added as backgroundimages in the view. NE icons grouped together with bindings form networks.The NE icons change their severity colours according to the current mostsevere alarm of the NE.

Figure V-6 Example of Map View

By pressing the right mouse button on a NE icon in the Map View andselecting Alarms from the context menu, a Current Alarm List (ref. AppendixIII) is opened showing all alarms of the NE.

3.4.4 Viewing Alarms in the Current Alarms ViewThe Current Alarm View can be opened by selecting Current Alarms fromthe Fault Menu. Figure V-9 shows an example of the Current Alarms List.Each alarm is listed as a row in the list as shown in Table V-1.

The Current Alarms List can also be opened from both the Explorer Viewand the Map View by selecting Current Alarms from the right-mouse-button-click context menu. The filter is then automatically set up to showonly the alarms hierarchically below the node/leaf the alarm list was openedfrom.

4.0 Cable FaultIf a cable fault is indicated, it indicates that microprocessor communicationsbetween the IDU and ODU have failed. The fault is most probably with thecable connection. It may be open or shorted. Disconnect the cable connec-tion to the IDU and leave the connection to the ODU connected. Measurethe DC cable resistance between the centre pin and the outer of the N-typeconnector terminating the cable by means of a multi-meter.

If resistance is in the order of some hundreds kΩΩΩΩΩ to a few MΩΩΩΩΩ:Probably no cable fault.Replace IDU or ODU, one at the time. If alarm persists, swap the replacedunit for the original and replace the other unit.

If resistance is less than some hundreds kΩΩΩΩΩ:Probably cable or connector damage. Check the cable and connectors atboth ends for defects or for reasons that would cause the problem. Remeas-ure DC resistance, now with both cable ends disconnected. The resistanceshould be “open circuit” and if not replace the entire cable run, terminatingwith new N-type connectors.

If resistance is immeasurable (high impedance):Typically reasons are connectors not terminated correctly or cable cut.Check the cable and connectors at both ends for defects or for reasons thatwould cause the problem. Remeasure DC resistance, with the outer end stillconnected to the ODU. If still immeasurable impedance, replace the entirecable run, terminating with new N-type connectors.
