WARNING!
DO NOT remove or insert theTransmitter Unit with DC power on.
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 PC boards,special precautions to avoid ESD have to bemade.
These precautions include personnel grounding,grounding of work bench, grounding of tools andinstruments as well as transport and storage inspecial antistatic bags and boxes.
CLASS 1 LASER PRODUCT
IEC825-2: 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:
Never look directly into an open connectoror optical cable
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.
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:
During work within and close to the frontof the antenna; make sure that transmitterswill remain turned off.
Before opening coaxial - or waveguideconnectors carrying RF power, turn offtransmitters.
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 IDU2.1 IDU Description
Figures X-1 shows the IDU front layout. All the connectors are located onthe front for easy operation. In addition to the line interface, 2Mbit/swayside and 64kbit/s data channels are available. As options, a 21x2 Mbit/s terminal multiplexer, ADM STM-1 (X-Connect) or DS3/E3 can be config-ured by adding a second circuit board. The IDU is equipped with anintegrated 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. For configuration and management purposes theIDU is equipped with two LCT interfaces for connection to the PC, one withRS-232 interface and one LAN TP interface. In addition NI interfaces forconnection to other IDUs or other Nera equipment are provided. A SETSfunction is incorporated into the unit, conforming to ITU-T rec. G.823 withbalanced 120Ω interface. The IDU has a connector for alarm input/outputfunctionality (ALM/AUX). Alarm and warning LEDs are located on righthand side of front. Located close to the power connector is a power indicatingLED.
Figure I-1 shows a block schematic view of the IDU with various optional lineinterface plug-in boards and also a 21x2 Mbit/s Extension Board. In radiotransmit direction, the 155 Mb/s input signal from the line interface board isfed to the “SORP” ASIC. It performs all the SOH processing and radioscrambling. Then, the TX FPGA encodes the signal by use of a convolutioncode and an optional Reed Solomom code. The signal is then mapped intoa “32TCM”, “64TCM” or “128TCM” constellation, as required. It alsoperforms the necessary pulse shaping by use of a digital FIR-filter. The signalis then digitally I-Q modulated, and the 350MHz IF signal is fed to the ODUinterface and applied to the IF coaxial connector. In receive direction the140MHz IF from the ODU will interface the IDU on the same connector. Thenecessary cable equalizing functions are provided in the ODU interface andthe equalized IF is presented to the coherent demodulator. From the demod-ulator the signal is fed to the RX FPGA, which perform slope equalization andreceive filtering. Then the “ATDEC” ASIC, performs Trellis decoding, by useof soft decision and the “Viterbi” algorithm for error correction. The optionalReed Solomon decoding is performed in the RX FPGA. The decoded signalis then fed to the SORP ASIC for radio descrambling and SOH processing,and is finally fed to the line interface board.

2.2 Hot Standby IDU DescriptionFigure X-2 shows the HSB IDU front layout. The connectors on the frontare identical to the ones used on the IDU and is therefore not furtherdescribed here. Additionally, a second power connector is added forpower redundancy enabling separate battery courses. Figure I-2 shows ablock schematic view of the IDU with various optional line interface plug-in boards. Interconnection of data and control signals between IDUs (A andB) and HSB IDU is by means of a connector and special split cable. Thiscable is part of the HSB cable kit. In a 1+1 HSB system, all the customerinterfaces are towards the HSB IDU. These signals are disabled on the IDUin such a configuration. The same alarm and warning LEDs used on IDU isalso used here. Additionally, a second power indicating LED is locatedclose to the redundant power connector. Also, an array of four LEDs,located on the right hand side in close proximity to the alarm/warningLEDs, indicates switching status in transmit and receive direction.

ADM STM-1, which is a part of the Indoor unit in theNERA CityLink, is an optional ITU-T standard STM-1 interface implementedfor 155 Mbit/s signal entry and exit in a ring topology. The STM-1 entry signalinto the ring is split and transmitted to line and radio side in parallel. Signalsexiting the ring are received from line and radio side. These are up to 63xVC-12s from either side and they are protected, i.e. they shall be switchedindividually if a break somewhere in the ring occurs. Also, the system willhandle any allowed combination of VC-3s and VC-12s.

Agreen LED, located on the front of the board indicates presence of an inputsignal. The line interface board is mounted on the extension board prior tothis being mounted within the IDU cabinet. This means that the line interfaceboard will not be used as a plug-in type board in this application.
SOH processing and line scrambling /descrambling on the STM-1 interfaceare performed by the SORP ASIC. The TDM1 ASICs perform insertion,extraction, signal processing and cross-connection of data in the payloadof the STM-1 frame and also make error and performance measurements onVC-3 and error measurements on VC-12. The PLD14 FPGA makes perform-ance measurements on VC-12s embedded in the STM-1 datastreams fromtwo TDM1 ASICs. The measurement results are used to choose individualVC-12s from the two datastreams in TDM1 ASIC no.1 and TDM1 ASIC no.2.The selection is done by the SU in TDM1 ASIC no. 3. See Figure I-5.

2.6 3xDS3/E3 and DS1 Extension Board (option)DS3 is a 45Mbit/s PDH standard used for the North American marked, E3 is34Mb/s PDH standard used for the European marked and the DS1 is a1.5Mbit/s PDH standard used for the North American marked. The 3xDS3/E3 and DS1 Ext. Bd., which is a part of the Indoor unit in the NERA CityLink,will perform add-drop of 3xDS3/E3 PDH channels to-from a STM-1 frame. Inadditional it will perform insertion and extraction of 1.5 Mbit/s wayside (DS1/T1).
In Figure I-6, a block schematic of the 3xDS3/E3 and DS1 Ext. Bd. functionsare shown. The 3xDS3/E3 and DS1 Ext. Bd. will interface three DS3/E3 andone DS1 line signal in Tx- and Rx-direction. The line interface circuit includes;cable equalizer, line coding and pulse shaping functions. This is performedby two Line Interface Unites (LIU), one for DS3/E3 an one for DS1. SOHoverhead and radio processor is located oh the motherboard in the IDU.
The PLD15 FPGA maps the 3xDS3/E3 into three VC3s, then into a VC4 andthen into a STM-1 signal and de-maps in the opposite direction. The STM-1 signal is locked to a 2.048 MHz input (SETS) coming from the motherboard.The TDM1 ASIC performs insertion, extraction and cross-connection ofdata in the payload of the STM-1 frame. Together, the two TDM1s and PLD15implement the core of a DS3/E3 add-drop multiplexer. The 1.5 Mbit/sWayside (DS1/T1) function is implemented in PLD15 and is independent ofthe TDM1 ASICs.

2.6 Ethernet Extension Board (CityLink Fast Ethernet)In Figure I-7, a block schematic description of an Ethernet Extension Board(EEB) is given. This function enables 4 separate Ethernet channels 10BASE-T/100BASE-TX and 4 separate 2Mbit channels conforming to ITU-T rec.G.703. The EEB will treat all 8 channels separately, meaning that all dataentering on one channel will leave on the same channel on the other side ofthe radio hop. All channels are full duplex. The four Ethernet and four 2Mbit/s channels shares the STM-1 data capacity. The 2Mbit channels, if enabled,will always be guaranteed full bandwidth. The 4 Ethernet channels can beconfigured to either equally share the STM-1 data frame, or one channel canbe given priority. The EEB has a limited on board Ethernet package buffercapacity. This gives the ability to handle short time 100Mbit/s bursts on allfour channels without package loss. Also the EEB supports flow control,making it possible to configure a 400Mbit full duplex network withoutpackage loss, even though the radio hop is limited to STM-1 data rate.

3.0 ODU3.1 ODU Type I Description
The ODU Type I is an assembly of branching unit and transceiver unitmounted behind the antenna or on a mounting frame on a pole/column. TheODU is connected to the IDU with a single coaxial cable. The coaxial cableprovides Tx-IF, Rx-IF, signalling and power supply. For flexibility and easy
installation, the coaxial cable is con-nected to the transceiver through thebranching unit. The transceiver is at-tached to the branching with a snap onsystem. With this solution, the coaxialcable may remain connected duringtransceiver replacement. In 1+0 con-figuration the branching unit is for asingle transceiver and in Hot Standbyconfigurations the branching is for dualtransceivers. The ODU and the antennaare assembled very closely togethermaking it very compact. Neverthelessthe antenna can be separated from theODU by use of a flexible waveguide.
The branching unit contains RF channel filters, circulators and overvoltageprotection. The Hot Standby branching contains in addition a RF switch fortransmit direction and a RF power splitter for the receive direction.
The transceiver unit contains a microwave Tx/Rx module, a synthesisedlocal oscillator and a transceiver main board, all in a waterproof housing.The transceiver is based on dual frequency conversion in the transmitterand triple conversion in the receiver. This radio architecture with high IFfrequencies allows for use of wide band branching filters while stillmaintaining excellent spectrum purity in transmitter and high selectivityin receiver. The use of wide band branching filters allows for a wide choiceof remote channel frequency selection without changing hardware.
The microwave module is an integrated multi-chip module with GaAsHEMT MMICs for Power Amplifier and Low Noise Amplifier. Thenecessary LO frequencies for the frequency converters are generated ina low phase noise synthesiser unit. The channel frequency is remotelyprogrammed from the indoor unit. Transmit/receive IF-chain, control-circuits, signalling and power supply are integrated on the transceiver mainboard.

3.2 ODU Type II DescriptionThe Type II of the ODU consists of a weatherproofbox containing the branching system. The ODUbox is mounted on a pole/column behind the anten-na. The Transceiver unit is a plug-in unit mounted inthe box. In 1+0 configuration the ODU box con-tains a 1+0 branching unit for a single transceiverand in Hot Standby configurations the ODU boxcontains a Hot Standby branching unit and dualtransceivers. The branching unit contains RF chan-nel filters and the diplexer. The Hot Standby branch-ing contains in addition an RF switch for transmitdirection and an RF power splitter for the receivedirection.
The transceiver unit contains 7 modules/sub-units;a microwave transmitter module, a receiver mod-ule, 3 local oscillators, an IF &controller board and a detector board. Thetransceiver is connected to the modem/IDU with a single coaxial cable thatcarries Tx-IF, Rx-IF and signalling (MTcom). Power is supplied througha separate connector (D-sub), and for the split mount case this power isseparated from the coaxial cable in the ODU container (box).
The transceiver utilises a single conversion scheme in the transmitter anda dual conversion in the receiver. In order to obtain an optimum spectrummask, the transmitter chain contains predistortion circuitry at IF beforethe microwave upconverter and power amplifier. Narrow channel filters inthe branching unit further reduces the spectrum mask. The second convert-er in the receive chain allows for an IF loop-back facility for diagnosticspurposes. LO frequencies for the microwave frequency converters aregenerated in synthesised DROs. The oscillators are by nature fixed infrequency, i.e. they can only be remotely programmed within a narrowrange. When necessary, the oscillators can be adjusted within a range ofapprox. 200 MHz with a mechanical screw (see Section VII Chapter4.5.2.3 for guidance). Power supply, transmit/receive IF-chain, signallingand controller (DSP) for the transceiver are integrated on the IF &control-ler board.
The branching unit contains narrow RF channel filters and circulators.

3.3 ODU Type III DescriptionType III of the ODU consists of a singleODU (in 1+0 configuration) mountedbehind the antenna and attached to theantenna by means of four snap-onclamps. The ODU is connected to theIDU via a single coaxial cable whichcarries transmitter IF, receive IF andcontrol and monitoring signals, as wellas DC power. In 2+0 and 1+1 hot stand-by configurations both ODUs are at-tached by the same snap-on clamps to abranching hybrid. This hybrid can ei-ther be bolted directly to the antenna orvia a short length of flexible waveguide.The branching hybrid contains an RFsplitter and combiner.
The ODU consists of a weatherproof housing containing a microwavetransmit/receive module, a synthesised local oscillator module and an IFand control transceiver main board. The transceiver is based on a dual up-conversion and triple down-conversion scheme, which allows the use ofwide-band duplex filters and therefore a wide choice of remote channelfrequency selection. To optimise the transmitter spectrum the transmitteremploys pre-distortion at IF as well as cable equalisation to correct forvariable loss and slope in the cable.
The microwave transmit/receive module consists of a multi-chip moduleusing a set of GaAs HEMT MMICs, both for the transmitter poweramplifier and the low-noise receiver. The required local oscillator signalsare fed from the synthesised local oscillator module and up-convertedusing a diode multiplier. The channel frequency is remotely selected viathe IDU. Transmit/receive IF multiplexing, control and monitoring andpower supply functions are all 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 QECC, accordingto ITU-T Rec. G.784, is provided.
As an option, the CityLink also supports embedded SNMP agent that canbe controlled by 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 AppendixI; IDU Interface Description.

5.2 Hot Standby ConfigurationIn Hot Standby configuration the IDU, the transceiver unit, and the coaxialcable between IDU and ODU are duplicated. The two transceivers share thesame branching unit/hybrid. A switch at radio frequency level, included inthe branching unit 1, allows for switching between the two transmitters. ASwitching Unit is placed between the two IDUs and performs hitlessswitching in the receive direction. The STM-1 line interface and Multiplexplug-in modules are mounted in this switching unit. Signal interconnectionbetween the IDUs and the switching unit is by a multi connector and a splitcable.
1) Some ODU types use a passive combiner/splitter at RF level.

1.0 GeneralThis section assumes that pre-planning of the link has been performed, i.e.path budgeting & survey to ensure good line-of sight between the two linkends.
1.1 PackingAny sensitive product, i.e. IDU and Printed Circuit Boards, are packed inspecial antistatic handling bags or boxes.
It is therefore essential that whenever unpacking or disassembling theequipment and or handling printed circuit boards etc., special precautionsto avoid ESD (Electro Static Discharge) should be taken, such as usingwrist grounding or corresponding protection.
The equipment is packed in sealed plastic bags which are equipped withrequired moisture protection.
All equipment is further packed in special designed cases prepared fortransportation.
Dimensions and weight of each case are specified in the "Packingspecifications" issued for the respective shipment.
1.2 MarkingMarking is done according to customers requirements. If such informa-tion is unavailable, the equipment is marked in the following way:
Customer addressContract No.Site Name (if known)Case No.
1.3 TransportationThe transport containers are prepared for shipment by air, truck, railwayand sea, suitable for handling by fork-lift trucks and slings.
The cargo must be kept dry during transport and storage.For sea-transport, deck-side shipment is not permitted and carrier-ownedcargo containers should be used.
B4008 Rev. M 51
ODU Type I Installation
1.4 Radio Equipment Inventory CheckLook for damage on the cases. Ensure that correct quantities of goods havearrived, according to the packing list in each package/unit.
Check also that the part description on the outside of each box corre-sponds to the components required for the installation, i.e. correct antennaand frequency, ODU frequency band and sub-band, IDU configuration.
Report any damages or missing items to Nera ASA by e-mail or fax. A shortdescription of damages, preferably including photographs, should be sentas soon as possible.
1.5 Preparation for InstallationComplete the required civil works. Transport all the equipment to site.Unpack the equipment and inspect for damage during transit to site andmake sure that the correct quantities of goods have arrived.
Units with static discharge protection should not be unpacked until theequipment installation takes place. Ensure you are grounded at a control-led ESD point before and during insertion, and during any subsequentunpacking of the unit.
1.6 Handling & StorageIt is recommended that components are stored and transported to theinstallation site in their original packing cases. If items are unpacked forstorage, they should be handled with care and protected during transpor-tation by similar protective materials.
The equipment is an electronic device which should be handled with care.It should be stored in dry, cool conditions, out of direct sunlight. Amoisture absorbing bag is taped inside the transportation unit to minimisecondensation during transportation. This is to be removed at installation.
No maintenance is required when stored according to particulars above.
To avoid damage to the sealing components and unwanted moist in theinterconnection interfaces, the transportation protection lids on the branch-ing and the transceiver must be kept on until mounting of waveguidecomponents and connection of the transceiver to the branching unit.

5.0 Frequency Tuning at 13GHz &15GHz TransceiverThis chapter gives a short description of how to set and change frequencychannel on the transceiver. To perform this operation it is necessary toremove the cover and mount the transceiver to a branching connected toan IDU. A PC (where Nera software NEW is installed) and power arefurther connected to the IDU. A voltage meter and a screwdriver must alsobe available.
• Switch on the power at the system• Set wanted frequency in New.
Tables II-1 to II-9 give the relation between selected channel, duplex, TXHigh/Low and RX High/Low. The illustration on the next page gives anoverview of the tuning voltage connectors (VT TX and VT RX) and tuningscrews.
WARNING!This equipment contains components which are sensitive to"ESD" (Electro Static Discharge). It is therefore essential thatwhenever disassembling the equipment and/or handling PCboards, special precautions to avoid ESD have to be made.
This includes personnel grounding, grounding of work bench,grounding of tools and instruments. For the tuning process,it is also recommended to use a ceramic screw driver.
• Measure the tuning voltage VT TX continuously while adjusting thetuning screw. First turn the tuning screw CCW as far as it goes. Thenadjust it CW until VT TX reaches the correct voltage:
For 15GHz Transceiver; 4±0.5[V]For 13GHz Transceiver; 3±0.5[V]
• Measure the tuning voltage VT RX continuously when adjusting thetuning screw. First turn the tuning screw CCW as far as it goes. Thenadjust it CW until VT TX reaches the correct voltage:
For 15GHz Transceiver; 4±0.5[V]For 13GHz Transceiver; 3±0.5[V]
After tuning VT TX and VT RX to the correct voltage, the transceiver isconfigured to the correct frequency channel. Inspect the gasket andreplace the cover with use of correct torque (1.25Nm).

1.0 GeneralThis section assumes that pre-planning of the link has been performed, i.e.path budgeting & survey to ensure good line-of sight between the two linkends.
1.1 PackingAny sensitive product, i.e. IDU and Printed Circuit Boards, are packed inspecial antistatic handling bags or boxes.
It is therefore essential that whenever unpacking or disassembling theequipment and or handling printed circuit boards etc., special precautionsto avoid ESD (Electro Static Discharge) should be taken, such as usingwrist grounding or corresponding protection.
The equipment is packed in sealed plastic bags which are equipped withrequired moisture protection.
All equipment is further packed in special designed cases prepared fortransportation.
Dimensions and weight of each case are specified in the "Packingspecifications" issued for the respective shipment.
1.2 MarkingMarking is done according to customers requirements. If such informa-tion is unavailable, the equipment is marked in the following way:
Customer addressContract No.Site Name (if known)Case No.
1.3 TransportationThe transport containers are prepared for shipment by air, truck, railwayand sea, suitable for handling by fork-lift trucks and slings.
The cargo must be kept dry during transport and storage.For sea-transport, deck-side shipment is not permitted and carrier-ownedcargo containers should be used.
B4008 Rev. M 93
ODU Type II Installation
1.4 Radio Equipment Inventory CheckLook for damage on the cases. Ensure that correct quantities of goods havearrived, according to the packing list in each package/unit.
Check also that the part description on the outside of each box corre-sponds to the components required for the installation, i.e. correct antennaand frequency, ODU frequency band and sub-band, IDU configuration.
Report any damages or missing items to Nera ASA by e-mail or fax. A shortdescription of damages, preferably including photographs, should be sentas soon as possible.
1.5 Preparation for InstallationComplete the required civil works. Transport all the equipment to site.Unpack the equipment and inspect for damage during transit to site andmake sure that the correct quantities of goods have arrived.
Units with static discharge protection should not be unpacked until theequipment installation takes place. Ensure you are grounded at a control-led ESD point before and during insertion, and during any subsequentunpacking of the unit.
1.6 Handling & StorageIt is recommended that components are stored and transported to theinstallation site in their original packing cases. If items are unpacked forstorage, they should be handled with care and protected during transpor-tation by similar protective materials.
The equipment is an electronic device which should be handled with care.It should be stored in dry, cool conditions, out of direct sunlight. Amoisture absorbing bag is taped inside the transportation unit to minimisecondensation during transportation. This is to be removed at installation.
No maintenance is required when stored according to particulars above.
To avoid damage to the sealing components and unwanted moist in theinterconnection interfaces, the transportation protection lids on the branch-ing and the transceiver must be kept on until mounting of waveguidecomponents and connection of the transceiver to the branching unit.

1.1 PackingAny sensitive product, i.e. IDU and Printed Circuit Boards, are packed inspecial antistatic handling bags or boxes.
It is therefore essential that whenever unpacking or disassembling theequipment and or handling printed circuit boards etc., special precautionsto avoid ESD (Electro Static Discharge) should be taken, such as usingwrist grounding or corresponding protection.
The equipment is packed in sealed plastic bags which are equipped withrequired moisture protection.
All equipment is further packed in special designed cases prepared fortransportation.
Dimensions and weight of each case are specified in the "Packingspecifications" issued for the respective shipment.
1.2 MarkingMarking is done according to customers requirements. If such informa-tion is unavailable, the equipment is marked in the following way:
Customer addressContract No.Site Name (if known)Case No.
1.3 TransportationThe transport containers are prepared for shipment by air, truck, railwayand sea, suitable for handling by fork-lift trucks and slings.
The cargo must be kept dry during transport and storage.For sea-transport, deck-side shipment is not permitted and carrier-ownedcargo containers should be used.

ODU Type III Installation
1.4 Radio Equipment Inventory CheckLook for damage on the cases. Ensure that correct quantities of goods havearrived, according to the packing list in each package/unit.
Check also that the part description on the outside of each box corre-sponds to the components required for the installation, i.e. correct antennaand frequency, ODU frequency band and sub-band, IDU configuration.
Report any damages or missing items to Nera ASA by e-mail or fax. A shortdescription of damages, preferably including photographs, should be sentas soon as possible.
1.5 Preparation for InstallationComplete the required civil works. Transport all the equipment to site.Unpack the equipment and inspect for damage during transit to site andmake sure that the correct quantities of goods have arrived.
Units with static discharge protection should not be unpacked until theequipment installation takes place. Ensure you are grounded at a control-led ESD point before and during insertion, and during any subsequentunpacking of the unit.
1.6 Handling & StorageIt is recommended that components are stored and transported to theinstallation site in their original packing cases. If items are unpacked forstorage, they should be handled with care and protected during transpor-tation by similar protective materials.
The equipment is an electronic device which should be handled with care.It should be stored in dry, cool conditions, out of direct sunlight. Amoisture absorbing bag is taped inside the transportation unit to minimisecondensation during transportation. This is to be removed at installation.
No maintenance is required when stored according to particulars above.
To avoid damage to the sealing components and unwanted moist in theinterconnection interfaces, the transportation protection lids on the branch-ing and the transceiver must be kept on until mounting of waveguidecomponents and connection of the transceiver to the branching unit.

Torque: 110-120Nm
6.2 Coarse adjustment.Adjust both antennas to correct direction as possible by using magneticcompass or optical sight.
6.3 Fine adjustmentFine adjustment is achieved by setting up a connection between theantennas. When the connection is established a readout of the AGC voltagecan be used to align the antennas. Loosen the antenna in both elevation andazimuth according to figure and adjust both azimuth and elevation untilmaximum signal is recived. Try a few times in each direction. The antennashould be turned so much that the first sidelobes are seen, thereby ensurethat the antenna is aligned on the mainlobe.
When the antenna is aligned in both azimuth and elevation the polarizationof the feed shall be realigned.
Finally ensure that all bolts and nuts are properly mounted and tighten.
The same procedure shall than be repeated on the opposite antenna.
B4008 Rev. M 129
ODU Type III Installation
6.5 Polarisation alignmentAlign the antenna approximately in both elevation and azimuth. Then usea water level to align the polarisation of the antenna feed to correctpolarisation according to figures below. Loosen the six M8 nuts that aresecuring the feed to the reflector and rotate the feed according to readoutof the water level. When the feed is in correct alignment, tighten the sixM8 nuts properly (do not overtight the nuts). Then the ODU can bemounted and the antenna has to be aligned. If the antenna has to be rotatedseveral degrees in azimuth or elevation, the polarisation has to be rea-ligned according to prior procedures.
Use these stud screws for aligning the feed with water level.
When the H mark is in upwards position, this shows that the antenna is Horizontal Polarized

Preparations for Operation
2.1 NEW-NMS/NEW-Configurator Startup andconnecting to Network ElementsThe NEW-NMS/NEW-Configurator (Nera Element vieW-Network Man-agement System/ -Configurator) program must be installed on a PCsatisfying the following minimum requirements:
• NT4.0/Win95/Win98 operating system• Pentium 133MHz processor• 32MB memory• 200MB disk size• 1 COM port• CD-ROM drive
Follow carefully the program installation instructions to make sure theprogram is successfully installed.
The element viewer can monitor the Network Elements (NEs) using aserial connection (RS-232) or a TCP/IP connection (or both for differentnetwork elements). Apply all external connections to the PC before theprogram 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 onto the network with your user id and password.
Note!NEW-NMS' security system has initially one user account:
User ID: adminPassword: adminpasswd
It is strongly recommended to change this password!
The program has an auto discover function which automatically discoversNEs connected to the serial ports of the PC when starting. If some NEs areconnected to the serial ports of the PC, the network topology is automat-ically discovered and presented in the Explorer view. Press Add to includediscovered elements in the network topology of the program. The autodiscover function can also be manually executed by selecting Discover

from the File menu. When discovering the network manually, the programlooks for NEs at the open ports listed in the Communication dialog box(select Communication 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 theprogram. A Log on dialog box pops up. Log on to the network with youruser id and password.
Note!NEW-NMS' security system has initially one user account:
User ID: adminPassword: adminpasswd
It is strongly recommended to change this password!
The program does not know the IP-address of the network element so theconnection must be manually established. To configure a TCP/IP connec-tion to the network element, select Communication from the Configu-ration menu. Press the Add button and type the IP address of the NE inthe 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 discoveredelements in the network topology of the program. The accepted networkelements will be discovered and presented in the Explorer view.
2.2 Initial configurationWhen the program has established contact with the CityLink, someconfigurations 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.Then select Configuration > Wizard from the right mousebutton contextmenu. Follow the Wizard instructions.
All the configuration settings are described in Section VII; Configuration.

3.1.2 Transmission Configuration, SW-version ≥≥≥≥≥ R2A00The Transmission Configuration sheet is used to set the transmissionstandard and termination on the element. When the applied termination isdifferent from RST, the sheet is also used to configure the SETS functionality.
A CityLink element may support different extension boards. This includesthe DS3/E3 Extension Board, the STM-1 Extension Board or the 21x2Mbit/s tributary board. Each element will, however, only support one extensionboard at a time. From the Transmission Configuration sheet the user canenable the functionality of the specific extension board. The 21x2Mbit/sextension board assumes a frame structure which contains 63 E1s. To enablethis board, select the termination to be Lower Order Path Termination -LOPT. If the DS3/E3 Extension Board or the STM-1 Extension Board ismounted, the frame structure must be set explicitly.
The Transmission Configuration configuration sheet can be opened fromthe Configuration context menu of the Transmission node in the Explorerview.

SSU Clock Source This field will only be enabled whenever theElement Type is set to either SSU (G.812Local) or SSU (G.812 Transit). The SSU is an
external clock regenerator or filter that will remove jitter fromthe clock on its input. It will then output a regenerated clock on itsoutput. The SSU is connected to the element via the
2MHz synch RJ-45 plug on the front of the IDU.The clock source can be one of the following:
• LINE• RADIO• Any dropped 2Mbit/s• LINE EXT
The last option will only be available if the X-Connect Extension Board is present.

SSU Squelch Level This field will only be enabled whenever theElement Type is set to either SSU (G.812 Local) orSSU (G.812 Transit). If the quality of the clock sourcechanges to a quality that is below this «qualitysquelch» level, the 2MHz synch output to the SSUwill be squelched. This in turn will cause the SSU toenter holdover mode (or free-running), i.e. the clockquality it sends to the 2MHz synch input will have aG.812 quality (ref. ITU-T Recommendation G.812)that is based upon the internal oscillator in the SSU.Legal squelch levels are:

If the Clock Source field for a specific prioritylist item is set to be taken from the 2MHz Synch input, or itis to be taken from a 2Mbit/s tributary, their clock qualityaren’t embedded in the traffic in any way. This meansthat the user will have to set their clock qualities manually.In these cases, the cell in question in this column will beenabled and the user can set the quality. Legal values are:
• G.813• G.812 Local• G.812 Transit• G.811
In addition to these, SSM will also be present in the list butcan not be selected.Note: Ref. ITU-T for more information regarding thedifferent G.8xx recommendations.

4.0 Equipment Node4.1 Network Routing
The active and initial routing tables map incoming messages that areaddressed to other NEs, to different communication ports.
The active routing table is used by the IDU to route messages to other NEs,using the best path detected. The IDU regularly searches for connectedNEs through all enabled communication ports to detect any changes in thenetwork topology. This table is initialised with the initial routing entrieswhen the IDU is rebooted (and when the initial routing table is configuredby the user) and then evolves towards an optimal routing table.
The initial routing table is used after the IDU has been booted. This tableis used as a starting point for the routing mechanism, and will thus, ifproperly set, decrease the time the NE uses to create a sufficient activerouting table. Initial routing entries can be manually added and activerouting entries can be copied to the initial table.
The Routing Table configuration sheet can be opened from the Config-uration context menu of the Equipment node in the Explorer view. Thesheet can also be invoked by selecting (highlighting) the Equipment nodein the Explorer view and then selecting Edit Routing Table from theConfiguration menu.

4.2 IP Routing
Static RoutesMaximum 20 static routes can be configured on a Nera OSPF router.
Active RoutesAn Nera OSPF router supports approximately 200 active routes.
OSPF areasIt is not recomended to have more than 25 OSPF routers per OSPF area.Each area may export up to 8 address ranges.
Fixed configuration optionsThe Nera OSPF implementation is not a dedicated router implementation andas such some parameters that would normally be configurable are fixed. Forinteroperability with other equipment it is however sometimes important thatthe configuration of external equipment match these values.
Name ValueInject default route into stub area YESRouter dead interval 40 secHello interval 10 secRetransmit delay 1 secRetransmit interval 5 secAuthentication NO
LimitationsThis implementation supports a basic implementation of OSPF v.2 (RFC2823). It does not support virtual links and MD5 authentication.
Other optionsThis implementation supports a rudimentary mechanism for distribution ofstatic and RIP2 routes. The implementation also supports exporting routesto RIP2.

4.4.5 DS3/E3 LoopingThe DS3/E3 card includes three PDH ports, each of which supports looping.The card supports Far End Loop, Near End Loop, PRBS insertion and PRBSverification. The loops are available when the PDH Ports on the DS3/E3 cardhave been configured to add or drop traffic.
A PRBS signal can be inserted on all three PDH ports instead of the regulartraffic. The incoming PRBS signal can then be checked in order to verify thequality of the communication path. To check the quality of the signal, a PRBScounter is configured to count the errors on one of the PDH Ports in one ofthe DS3/E3 directions. An error is detected when the signal differs from theexpected PRBS signal.
The DS3/E3 card has one PRBS generator that can be muxed into eitherinbound or outbound direction on one or more ports simultaneously. ThePRBS generator can be inverted. For E3 the PRBS polynom is 223 - 1 and forDS3 the PRBS polynom is 215 -1. The PRBS checker is available at one of thePDH ports in either inbound or outbound direction and can also checkinverted PRBS signals.

The XCVR Unit provides a set of RF power control functions:• RF input alarm thresholds can be set such that an alarm is raised when
the input level exceeds the upper or lower limits.• ATPC (Automatic Transmitter Power Control) is a function for effec-
tively reducing the interference probability in the network. When ATPCis enabled, the output power from the transmitter is automaticallycontrolled according the received input power on the other side of thehop. The ”ATPC” alarm is generated if the ATPC regulation loop fails.This alarm can be optionally delayed.
• If ATPC is not enabled, the transmitted output level can be set. Thetransmitter can also be muted.

6.1.1 FunctionalityThe IDU switch will perform most of the normal tasks of an IDU, with the twoIDUs maintaining modem functionality. Thus, configuration of line inputs,wayside channels etc will be handled on the switch, while modem-specificfunctionality (e.g Viterbi error pulses) is found on the IDU. Some function-ality, like auxiliary outputs, are found in both places.

Configuration with NEW-Configurator
Automatic Switch ModeThe IDU switch checks the state of both channel A and channel B regularly.This task decides whether an Rx switch is needed or not. Similarly, the Txswitching is controlled by the ODU. For the Tx switching to work, theconnected IDU signals the ODU when at least one of the switching criteriaare present on the IDU.
In automatic switch mode the following rule constrain switching:A channel switch is performed if, and only if, the channel switched to, hasno switch conditions true.
On IDU A and IDU B, a dedicated task is continuously checking whether theRx or Tx switch criteria status has changed, and if so, notifies the IDU switchand ODU about the change.
Currently, bi-directional switching is not implemented in automatic mode.
Switching algorithmThe following algorithm is applied in automatic switching mode:Compute the total severity factor of each branch (SA, SB) using the followingformula:
SCenabled1is 1 if the switching criteria “RF Input Alarm” is enabled (checked),else it is 0. SCactive1 is 1 if the alarm/category “RF Input alarm” is active(present) on the element, else it is 0.If SA = SB, switch to the preferred branch (The preferred branch is set in theHot Standby Config page)If SA > SB, switch to SB if branch A is active.If SB > SA, switch to SA if branch B is active.
Manual Switch ModeIn manual switch mode, bi-directional switching is performed only as a resultof a Q1 message from external management software (e.g. NEW-NMS).
Currently, unidirectional switching is not implemented in manual mode.

6.1.4 Reconfiguring a Hot Standby IDU foruse in 1+0 ConfigurationAn IDU that has been used in a HSB configuration will continue to beconfigured as a HSB element until explicitly reconfigured. To do this, firstdisconnect the IDU from the switch. Then use NEW-NMS to connect tothe element with a serial cable. NEW-NMS’ explorer view should nowdisplay an equipment tree with a single node. Bring up the Element IDdialog from the Configuration menu, and disable the Hot Standby check-box. When the element is next power cycled, it will start up in 1+0 configu-ration. This can be verified with the Element ID dialog.
6.1.5 Reconfiguring a 1+0 IDU foruse in Hot StandBy ConfigurationIf the IDU used in a 1+0 is to be prepared for an IDU in a HSB system, it isvery important to do the following procedure :
1.Connect the HSB cable between the IDUs and the switch2.Power up the HSB IDU3.Power up the IDU A and IDU B
The IDUs will now be automatically reconfigured as IDUs used in a HSBsystem.
WARNING!If the Y-cable connectors marked with IDU A and IDU B areswapped, the IDUs must always be rebooted after this opera-tion.

2.2 Testing• How to verify transmission quality and capacity ?
– One way to do this is to set up two computers and do a file transfer(FTP) between them over the hop.
One PC working as FTP-server and one as FTP-client, check thetime for transfer of the file and calculate throughput.
Do not have any HUBs connected during this test.
– Stability of the equipment and hop will be easiest monitored onBER test with pattern-generator on a 2Mb/s.
2.0 How to get this link aliveWhere to start– Status?– Do we want a IP connection to the IDU? If you have NEW-NMS, then
the answer is yes.Enable IP one of the four traffic port’s and do all settings fromNEW-NMS.

NOTE! In order for NEW-NMS to manage the SNMP element, the SNMPAgent settings configured locally must match the settings in the NEW-NMS. Please see the CityLink Fast Ethernet Agent Configuration.
NEW-NMS is using received traps for keeping an accurate element status.SNMP Traps are unreliable and no delivery guarantee is given, to over-come this weakness a query for number of traps sent from the SNMPelement must be performed from NEW-NMS at given time intervals. If thenumber of traps sent from the element is not equal to the number of trapsreceived from the element, traps have been lost and alarm synchronizationis needed.

3.0 Troubleshooting by NEW-NMS Configurator3.1 Introduction
Fault management is the process of locating and correcting networkproblems or faults. Fault management is possibly the most important taskin network management. It consists of identifying the occurrence of afault, isolating the cause of the fault and correcting it if possible. The faultmanagement increases the network reliability by giving the networkoperator a tool that quickly detects problems and initiates recoveryprocedures.
NEW contains functions for acquisition, presentation and storage ofalarms and events from the network to be managed.
3.2 Information AcquisitionIn order to detect faults, information must be gathered from the network.The state 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.
350 B4008 Rev. M
CityLink
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 eventsconsiderably.
3.3 Alarm PresentationIn all views, where network information is presented, colors are used toindicate the alarm severity status of the NEs. To easily identify the statusof the NEs, all alarms are classified according to their severity. Each alarmseverity class has a color. In the different views, the NEs change colorsaccording to the color of their most severe alarm. The alarm classifica-tions are described in the table below.
Severity Colour Description(default)
Normal Green No alarms or warning have been reportedfrom the NE.
Warning Yellow Indicates the detection of a potential orimpending service-affecting fault, before anysignificant affects have been felt. Actionshould be taken to further diagnose andcorrect the problem in order to prevent itfrom becoming a more 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 theNE. The communication settings should bechecked in order to obtain contact with theelement.
Misconfigured Magenta The NE has not been properly configured.
B4008 Rev. M 351
Troubleshooting
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 IX-1 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 Transmissionbranch concern the transmission aspects of the NE. The sub-branches andleaves under the Equipment branch concern the physical equipment of theNE.
Figure IX-1 Example of Explorer View
352 B4008 Rev. M
CityLink
The Explorer view use the severity colours to indicate alarm events. Thealarms are presented in a hierarchical manner. The colour of the mostsevere alarm is inherited from the leaf where the alarm was identified, toall branch leaves up to the section symbol. E.g. the section and NE symbolswill always show the alarm colour of the most severe alarm identified inthe sub-branches in the Explorer view.
By pressing the right mouse button on any nodes/leaves in the ExplorerView and selecting Current Alarms from the context menu, a CurrentAlarm List (ref. Appendix III) is opened showing all alarms Hierarchicalbelow the selected leaf.
3.4.2 Alarms on a Node symbol in the Map viewThe Map View is opened by selecting Map Navigator from the ViewMenu. Follow the instructions in the Help file to create a map. Figure IX-2 shows an example 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 formnetworks. The NE icons change their severity colours according to thecurrent most severe alarm of the NE.
Figure IX-2 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.Appendix III) is opened showing all alarms of the NE.
B4008 Rev. M 353
Troubleshooting
3.4.3 Viewing Alarms in the Current Alarms ViewThe Current Alarm View can be opened by selecting Current Alarms fromthe Fault Menu. Figure IX-3 shows an example of the Current Alarms List.Each alarm is listed as a row in the list as shown in Table IX-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 wasopened from.

4.0 Cable FaultIf a cable fault is indicated, it indicates that the microprocessor communica-tions between the IDU and ODU have failed. The fault is most probably withthe cable connection. It may be open or shorted. Disconnect the cable fromthe IDU and leave the ODU connected. Measure the DC cable resistancebetween the centre pin and the outer conductor of the N-type connectorterminating 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 replaced unitfor 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 at bothends for defects or for reasons that would cause the problem. RemeasureDC 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 endstill connected to the ODU. If still immeasurable impedance, replace theentire cable run, terminating with new N-type connectors.
