WARNING!Exposure to strong high frequency electromagnetic fields may causethermal damage to personnel. The eye (Cornea and lens) is easily exposed.

Any unnecessary exposure is undesirable and should be avoided.

In Radio-Relay communication installations, orderly setup for normaloperation, the general RF radiation level will be well below the safety limit.

In the antennas and directly in front of them the RF intensity normally willexceed the danger level, within limited portions of space.

Dangerous radiation may be found in the neighbourhood of open waveguideflanges or horns where the power is radiated into space.

To avoid dangerous radiation the following precautions must be taken:

r During work within and close to the front of the antenna; makesure that transmitters will remain turned off.

r Before opening coaxial - or waveguide connectors carrying RFpower, turn off transmitters.

r Consider any incidentally open RF connector as carryingpower, until otherwise proved. Do not look into coaxialconnectors at closer than reading distance (30 cm). Do not lookinto an open waveguide unless you are absolutely sure that thepower is turned off.

WARNING!

This equipment contains components which are sensitive to "ESD" (ElectroStatic Discharge).

It is therefore essential that whenever disassembling the equipment and/orhandling PC boards, special precautions to avoid ESD have to be made.

These precautions include personnel grounding, grounding of work bench,grounding of tools and instruments as well as transport and storage in specialantistatic bags and boxes.

B1094 Rev. D 9

WARNING!

r DO NOT remove or insert the Transmitter / Receiver group with DCpower on. See Section V - Unit Replacement for details.

r To avoid traffic disturbance during maintenance on one of the RFchannels in a 1+1 protected system, the traffic should be manuallylocked to the protection channel before any work is started.

n1.1 PackingAny sensitive product, i.e. Printed Circuit Boards, are packed in specialantistatic 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) have to be made, such as usingwrist grounding or corresponding protection.

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:

Customers 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 forklift 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.

1.4 Storing and Inspection Upon ArrivalLook for damages on the packaging. Count the number of cases receivedagainst shipping documents.

Report any damage or missing items to Nera ASA by telex or fax. A shortdescription of damages, preferably including photographs, should be sentas soon as possible.

1.0 PACKING, HANDLING AND STORING

24 B1094 Rev. D

The equipment is an electronic device which should be handled withcare. It should be stored in dry, cool conditions, out of direct sunlight.A moisture absorbing bag is taped inside the unit to minimise conden-sation during transportation. This is to be removed at installation.

No maintenance is required when stored according to particulars above.

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 untilinsertion into its place (slot) in the equipment takes place. Dischargeyourself before insertion of the unit.

1.6 HandlingIt 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.

A flexible waveguide is used between the ODU Box and the Antenna feed.

The waveguide flange on the ODU box and in most cases on the antennafeed, are made of aluminium. The flanges of the flexible waveguide arenormally made of brass.

Note 1Waveguide flanges made of different materials such as aluminium andbrass shall never be directly connected as galvanic corrosion will occur.A bimetallic shim must be inserted between the flanges. This shim has acopper surface at one side and aluminium on the other. Make absolutelycertain that the aluminium side faces the aluminium flange. The bimetallicshim is part of the Gasket/Screw Kit.

Note 2Use two alignment screws at the waveguide flange (short sides) in orderto align the shim and mating the flange correctly to the flange of the ODUBox. Alignment screws are part of the Gasket/Screw Kit.

Note 3Apply silicon sealing compound around shim edge and flange after mount-ing, to prevent any ingress of water. (Sealing compound is not part of theGasket/Screw Kit.)

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 bothantennas.

7.1 Procedure for Coarse-alignmentAdjust both antennas to correct directions as precisely as possible byusing magnetic compass or optical sight.

7.2 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 Meter

The AGC Voltage is available at a test point on the rear side of the ODU.

60 B1094 Rev. D

Mute the transmitter at the receive station to exclude interference fromthis source.

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

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 until the received signal is at maximum level. Try a few timesin each direction.

The antenna should be turned so much 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.

7.3 Cross Polarization AdjustmentAfter alignment of the antenna, the antenna feed should be adjustedhorizontally and vertically. Loosen the flange which secures the feed tothe reflector. Align the feed by using a spirit leveller. Secure the flange.

7.4 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.

1.0 GENERALThis chapter describes how to operate the equipment and do simple cableconnections, unit/circuit board replacements etc.

2.0 BOARD/UNIT REPLACEMENT

When properly installed (see the installation procedure) the NL18x-Bequipment is very easy to maintain. However a few things have to beobserved:

If a circuit board has to be removed from the IDU or ODU, check that allcable connectors on the board, if any, has been disconnected.

Note!Never try to pull out a circuit board with the cable connectors inplace.

When removing cable connectors, always do it very gently in order not todamage the board connectors.

See Fig 3-2.

When a cable connector is to be connected to the equipment, always do itvery gently.

When a circuit board is to be removed, use the board-ejector(s), if any,very gently.

If a new circuit board is to be installed, observe that the board-ejectors arein line with the front of the board before it slides into position in the shelf,see Fig. 2-1.

If a Transceiver or a Modem or both has to be removed, the correspondingpower supply should be switched off before the units are removed.

If the Modem board in the ODU is to be removed, the Transceiver unitcovering it must be removed first, then the Modem can be pulled out. Thiscircuit board however, has not the same board ejectors as the other boardsbut a shielding metal front, grab this front on top and bottom and pull outthe board.

64 B1094 Rev. D

CIRCUIT BOARDBOARDEJECTOR

SHELF

A new board is inserted into the same position by grabbing the metal frontin the same manner.

When the transceiver is to be replaced, a torque wrench must be used totighten the RF-connectors. Use a torque of 0.55Nm.

When removing the power supply, be careful not to damage the contactstrips on the right hand side of the unit.

3.4 Telephone Connection

3.4.1 Selective Call VersionThe Service Channel Interface Unit (SCI) is connected directly to theomnibus without switching. Therefore no signalling is necessary to bethrough connected. Once any telephone is off hook, it is connected.

r Use of collective call- When *-button or «Call»-button is pushed on any station, there will be aring in all telephones connected to the omnibus. The ring will last as longas the button is held.

r Use of selective call- The two digits has to be sent within approx. five seconds. If one of thesedigits is wrong, just wait for five seconds and then send two correct digits.The correct telephone will then ring in two periods of approx. one second.If a telephone has been reached with the selective number, a tone can beheard on the omnibus channel.

r External Loudspeaker- The loudspeaker output is normally open on all stations. To mute all thespeakers connected to the omnibus, lift off your telephone and press #.(This will also activate the Control 2 signal).

74 B1094 Rev. D

3.5 Parity Error MeasurementsParity Error Measurement is available on TB1 (See Fig. 3-1 and SectionIII, Chapter 14.2.4). When a pattern receiver is connected to the ParityError connector it will momentarily show one error, this is because theoutput from the Parity Error driver is inverted. This means that the firsterror, shown on the pattern receiver, should be subtracted from the finalresult to get a correct measurement.

3.6 External Insert Channel SynchronizationExternal Insert Channel Synchronization is available at J90 (See Fig. 3-1and Section III, Chapter 5.1).

See ITU-T rec. G.703 for signal specifications.

4.0 SYSTEM OPERATIONThe following subchapters describe how to operate different parts of theCelLink equipment to obtain maximum performance.

4.1 Front connections on Transceiver and ModemThe Transceiver Unit has connections for input/output of RF and IF signalson the front. A separate output for RF-input level voltage is also supplied,this is the same voltage which is available trough the Supervision system,accessible on the Hand Held Terminal, (HHT), the operation of the HHTis described in Chapter 5.0, this voltage can be monitored by a multimeter. Each Transceiver and connected Modem are supplied by a separatepower supply. This makes it possible to switch off only one Transceiver/Modem combination without disturbing the other Channel in a 1+1system. When monitoring the RF input level, ground for the multimetercan be found on top of the radio shelf, below the upper grip.

Fig. 4-1 Shows the front of the Transceiver unit. Each connector andalarm LED is named to simplify user operation.

4.2 Use of Switches on front of circuit boardsThis subchapter describes how the switches on front of different circuitboards are operated and their functionality. The descriptions start with thecircuit boards in the ODU.

A standard Frequency Diversity terminal has no circuit boards in the ODUwith switches at the front. A Hot Stand-by terminal however has the “HotStand-by Switch Control” board with a switch on front of it which may beoperated to lock the transmission on to one of the XMTRs. This circuitboard is shown in fig. 4-2, with explanation on how to use the switch.

10.1 Straps

10.1.1 Strapping of PABX AdapterCheck that strapping on the PABX Adapter is correct before installing theboard.

Strap Position CommentsW100 1 - 2 * Pos 2 - 3 used for factory testingW101 1 - 2 * Pos 2 - 3 used for factory testingW103 ON * Removed only during factory testW104A 1 - 2 Radio system with negative batteryW104B 4 - 5 pole connected to groundW104A 2 - 3 * Radio system with positive batteryW104B 5 - 6 * pole connected to ground

* = Normal Position

Select the calling number (address) for Adapter by setting one switch inON position on the 10 pos. DIL-Switch (S100). The figures from 0 - 9 ismarked on the PCB. E.g., if 8 is chosen, #8 have to be dialled to getconnected to the PABX. Off hook and detected # will start a necessarycontrol signal to connect a PABX, and when 8 is detected on the Adapter,the correct PABX is connected to the party line.

10.1.2 Strapping of Service Channel, 2NF468A/B2W (two-wire) from PABX is connected via the DDF panel to the Adapterby means of a spesial cable. Connect the 2W to pin 36 and pin 37 (37pinsD-sub).

Set strap W101 and W102 in pos 1-2, 4-5 and 7-8 to route the actualsignals between 2NF468A/B and 2N579A via the cable.Set strap W210 ON. This strap simulates an off hook situation for thevoice band and leads to a constant full D/A - A/D convertion. This isnecessary whenever any analogue connection is made to J1.

The voice frequency signal connection between the Service Channel boardand the Adapter board is 4W to obtain galvanic isolation between thePABX and the Radio equipment. If the line loss is high, it is possible tocompensate for the loss in signal level by adjusting attenuators on theService Channel board.

188 B1094 Rev. D

DIL-Switch S601 is for signals from PABX, while S602 is for signals toPABX. (See chapter 7.2 this section or handbook for 2NF468A/B).The strap W604 must be ON to route the 4W input internally on 2N533A.

10.1.3 System Strapping and Wiring of Control SignalThe figure on next page shows a principle schematic diagram fordistribution of Control signal .

On repeaters, the control signal is internally distributed.

Between terminals, the control signal must be distributed by strappingCtrl2 (out) to Ctrl1 (inp).

Ctrl2 (out): J1-34Ctrl1 (inp): J1-33

Depending on positive battery (Negative Station Ground) or negativebattery (Positive Station Ground), Ctrl Signal must be strapped on2NF468A/B:

12.1 Delay and Delay CalculationDelay of the signal received at the Combiner Board Space Diversity,8DFK131A, is unequal due to the difference in guide length from Mainand Space antenna. This delay is compensated by use of Equalizer LineSD Board, 8F302A. The delay difference must be calculated (see below)and preset.

Delay is calculated using the following formula:τ = 3.3 * L

where τ is delay in nanoseconds., and L is guide length difference inmeters.

12.2 Delay SettingThe delay shall be set from the Control Board SD, 3KN212A, not fromthe Equalizer Line SD Board.

1. All switches on Equalizer Line SD Board should be set to off (factorypreset).

2. Turn switch 1 on S86 to ON. This enables delay setting from theControl Board SD.

3. Set switch 2-8 according to calculated delay. See markings.

12.3 CalibrationCalibration of Space Diversity is necessary to establish nominal signallevels at Combiner Board SD detectors. The procedure is done onlyonce, but always after a modification or change of units in the radio group.

1. Turn switch 4 on S87 to on. This enables the calibration routine.2. Reset the Control Board SD by pressing S800.3. Connect Modem IF OUT to Space Diversity Combiner Board's

15.1 Protection Unit

An electrical cable interconnection between IDU and ODU requires anover-voltage protection for both the 8.96 / 37.356 Mb/s lines and thepower supply. This to prevent an equipment breakdown during lightning.The lightning protection unit is an integrated part of the connection panel.

The power supply to the ODU will usually be distributed from the IDU, buta supply from a local power supply is optional (by using conn. P2). TheFigure below shows the settings for “Normal Position” (supply fromIDU) and “Local Position” (local supply).

1.0 FREQUENCY SETTING PROCEDURE, 7-13GHz

The radio frequency of the CelLink Family is controlled by fre-quency synthesizers.

The radio channel is selected by internal DIP-switches in the radiounit. Changing radio channel is done by the following step by stepprocedure.

Note! Extension card or cable has to be used during thefollowing procedure.

1. Remove the small cover in the lower part of the XCVR or spacediversity RCVR unit.

2. S101 is used for choosing the XCVR to be used in a Space div. systemor not. If the XCVR is not used in a Space div. system, dipswitch 3 and4 shall be "0" (MAIN). If the XCVR is used in a Space div. system,dipswitch 3 and 4 shall be "1" (SP). Dipswitch 1 and 2 are used forproviding the right LED to illuminate, when tuning the DRO. If theDRO has a resonator fastened to the tuning screw, the frequency of theDRO will decrease when turning the tuning screw towards the resona-tor. In this case dipswitch 1 and 2 on S101 shall be "0" (RT (resonator-tuner)). This is the situation for the 5 GHz DRO's only, and will bepreset from the factory.

If the DRO is equipped with a metal-tuning screw only, the frequencyof the DRO will increase when turning the tuning screw towards theresonator. In this case dipswitch 1 and 2 on S101 shall be "1" (MT(metal tuner)). This is the situation for all other DRO's, and is presetfrom the factory.

3. The transmit and receive frequencies are set separately. S401 controlsthe receiver frequency and S501 the transmitter frequency.

4. Identify the actual channel in tables on the next pages. Find the corre-sponding binary setting for the switch (right column). The physical switchsetting for S401 and S501 is explained in figure 1-1.

5. Set the correct switch positions (S401) and press S402. The LED H401and one of the LEDs H101 or H102 should illuminate.

218 B1094 Rev. D

6. Adjust the Receiver oscillator tuning screw (situated on the rear sideof the Transceiver unit, near the top) according to the LED indicatorsH101 and H102. Adjust the tuning screw slowly to avoid that the rightfrequency is passed.

a) If H101 is on; turn the tuning screw clockwise until H101 turns off.

b) If H102 is on; turn the tuning screw counter-clockwise until H102turns off.

Both LEDs and LED H401 should be off after this adjustment, assumingan ambient temperature between +20ºC and +30ºC.

7. Press S402 once more to verify proper adjustment.

8. Set the correct switch positions (S501) and press S502. The LEDH501 and one of the LEDs H103 or H104 should illuminate.

9. Adjust The Transmitter oscillator tuning screw (situated on the bottomside of the transceiver unit) according to the LED indicators H103 andH104. Adjust the tuning screw slowly to avoid that the right frequencyis passed.

a) If H103 is on; turn the tuning screw clockwise until H103 turns off.

b) If H104 is on; turn the tuning screw counter-clockwise until H104turns off.

Both LEDs and LED H501 should be off after this adjustment, assumingan ambient temperature between +20ºC and +30ºC.

2.0 FREQUENCY SETTING PROCEDURE, 15GHz

The radio frequency is controlled by a frequency synthesizer.

The radio channel is selected by an internal DIP-switch in theradio unit. Changing radio channel is done by the following step bystep procedure.

Note! Extension card or cable has to be used during thefollowing procedure

1. Remove the small cover in the lower part of the radio unit.

2. Identify the actual channel. See frequency tables in chapter 3. Findthe corresponding binary setting for the switch (right column). Thephysical switch setting for S401 is explained in figure 2-1.

3. Set the correct switch positions (S401) and press S402. The LEDH401 should flash briefly and one of the LED’s H101 or H102 shouldilluminate.

4. Adjust the oscillator tuning screw according to the LED indicatorsH101 and H102.

a) If H101 is on: turn the tuning screw clockwise until H101 turns off.

b) If H102 is on: turn the tuning screw counter-clockwise until H102turns off.

Both LED’s should be off after this adjustment, assuming an ambienttemperature between +20°C and +30°C.

1.0 GENERALBefore any error checking can be undertaken using the supervision systemthe following must be observed:

r The Supervisory unit must be functioning normally.

The two main equipment alarms, “Urgent Alarm” and “Main Alarm”,outputs are both given trough relays. The same outputs are also connectedto external outputs at the top of the IDU and shown by LEDs on front of theIDU.

Only a Hand-Held Terminal, (HHT), is required to carry out the faultfinding tests.

Note!The Trouble Shooting procedures are intended as a guideline forfault location and may not cover all fault constellations.

2.0 SYSTEM TROUBLE SHOOTING BY MEANSOF THE HHT

All trouble shooting is depending upon using the Hand-Held Terminal,(HHT), to check out internal unit and board alarms to pinpoint which unitor board who includes the faulty circuit. It is then a matter of interchangingthe unit or board by a new one and at the same time taking some simpleprecautions to avoid transmission interruption in other channels, 1+1systems, in the equipment.

The fault finding procedure is split into two parts, depending on whetherthe “Urgent Alarm” is lit or not. The “Urgent Alarm” is the most importantof the two main equipment alarms while the “Main Alarm” is the mostgeneral alarm in the system and thereby most likely to be observed as itincludes all sub alarms. The “Main Alarm” is thus always checked out firstwhen an alarm situation occurs and if the “Urgent Alarm” is also observedthe fault finding procedure is done on the basis of it. The flow diagramsused by the fault finding procedures are shown in chapter 3, “ERRORCHECKING FLOW DIAGRAMS”. All named alarms in the flow diagramsare listed in chapter 4. “ALARM LIST”.

246 B1094 Rev. D

2.1 Main AlarmThe “Main Alarm”, red LED, is situated in the mid part of the IDU's frontpanel, under the “Urgent Alarm” LED. When this LED is lit, an internalequipment alarm is detected on one or more units or boards. This alarmLED is also lit when the “Urgent Alarm” is on but not vice versa. The causeof the alarm may not be disastrous for the equipment and thus not needimmediate action. If the “Urgent Alarm” is on the fault finding procedurefor that situation is used.

2.1.1 Fault findingThis procedure is based upon using flow diagrams, and starts out by usingthe “MAIN ALARM” error checking procedure, where it is first checkedout whether the “URGENT ALARM” is present or not, if yes the flowchartproceed to the “URGENT ALARM” error checking procedure. The “MAINALARM” procedure also uses the three sub procedures “SUB PROCE-DURE A”, “CHANNEL PROCEDURE” and “COMMON UNIT PROCE-DURE”. When the faulty unit or board is located, the next action is tointerchange it by a new one.

Fig. 3-1 shows the flow diagram for the “MAIN ALARM” errorchecking procedure.

2.2 Urgent AlarmThe “Urgent Alarm”, red LED, is situated in the mid part of the IDU's frontpanel. When this LED is lit, it signals a total, (all 2Mb/s channels for4x2Mb/s systems or the single 8Mb/s channel for 1x8Mb/s systems),main data transmission loss in one or more channels in the equipment.Insertion channels may also be lost while the alarm is on but that situationis not a required condition to trigger the alarm. This alarm requiresimmediate action to restore data transmission.

2.2.1 Fault findingThe fault finding uses the “URGENT ALARM” error checking procedure.The first action in the procedure is to identify the channel which has thetransmission break down and then checking all the power supplies. Thenext action is to check if it is a split mount system and do error checkingaccordingly by using the “SUB PROCEDURE A”, then checking out theRCVR and XMTR direction by using the “CHANNEL PROCEDURE”, ifit is a 1+1 system both channels are most likely to be out of function andhave to be checked out for errors by using the same procedure twice.

Fig. 3-2 shows the “URGENT ALARM” error checking flow dia-gram.

3.0 ERROR CHECKING FLOW DIAGRAMSThe following flow diagrams are divided into two parts one for the MAINALARM and another one for the URGENT ALARM. When URGENTALARM is detected this part is used firstly then the MAIN ALARM part.All alarm numbers given in the flow diagrams refer to the columnlabelled “HHT Alm. No” in the alarm list in chapter 4.
