WARNING
1. After turning ON the equipment, wait at least 1 minutebefore turning it OFF again. Repeatedly turning the powerON and OFF with in a short interval may cause the IDU tofail.
2. The –43 V DC power is superimposed on the centerconductor of the coaxial cable between the IDU and theODU. Connecting a test set equipment directly to thisterminal may damage it and touching the coaxial cable coremay cause electrical shock.
3. Persons performing servicing must take necessary steps toavoid electro-static discharge which may damage themodules on the IDU or cause error. Wear a conductivewrist strap connected to the grounded (G) jack on the frontof the equipment shelf. This will minimize static build-upduring servicing.
4. Do not disconnect IF cable between the IDU and the ODUin operating condition, to avoid damaging the IDU andODU. Do not remove/connect the IF cable with IDU powerON, turn IDU power OFF before remounting the IF cable.

2.4.2 Performance Monitoring/Metering Data Reporting
To monitor the transmission quality, the equipment is provided with theperformance monitoring and the metering functions. The CTRL modulepolls the different modules and gathers PM/Metering information. A “*”mark displayed in the PM results screen indicates that the value is illegal.A “#” mark is displayed if the PM results are obtained while the equipmentis in maintenance mode. When the equipment clock setting is changed orthe power is turned on/off, the PM value is judged to be invalid. Themonitoring items are as follows:
• Out of Frame Second (OFS)
• Background Block Error (BBE)
• Errored Seconds (ES)
• Severely Errored Seconds (SES)
• Unavailable Second (UAS)
• TX POWER
• RX LEVEL
• ODU PS MON
• Bit Error Rate (BER)
2.4.3 Automatic Transmitter Power Control
The automatic transmit power control (ATPC) function automaticallyvaries the TX output power according to path conditions. In the 6 to 38GHz band, fading exerts heavy influences on propagation, causing thereceive signal level at the opposite station to vary. The ATPC functionoperates by controlling the transmit output power of the opposite stationaccording to the variation of the received signal level at the local station.ATPC provides the following advantages:
• Improvement in up fading characteristics• Improvement in residual BER characteristics• Reduction of interference to intra system• Reduction of interference to inter system
SYSTEM DESCRIPTION ROI-S04051
2-24
A functional block diagram of the ATPC operation is shown in Fig.2-4. ATPC improves the BER characteristics under adverse changesin climatic conditions and reduces the possibility of interference. Toimplement ATPC, the receiving level (RX IN LEV) is detected bythe receiver (RX) and passed on to the CPU on the CTRL circuit ofthe MODEM module. The CPU then determines whether thetransmit output power needs to be controlled. This is based on thetransmit output power, the minimum and maximum values of theoutput control range, and the receiving threshold level that werepriorly specified using the LCT or PNMT.
A control signal (POWER CONT), whose function is to maintainthe RX signal by lowering or raising the TX output power of theopposite station, is generated by the MODEM module through theCPU circuit. This control signal is based on the result ofcomparison between the current receiver input level and the presetreceiving threshold level. This control signal is sent to the oppositestation to control its transmit output power.
At the opposite station, this control signal is detected by theMODEM module. The MODEM module, in accordance with thiscontrol signal, produces a control that will either raise, lower ormaintain the current TX output power. This control is based on thetransmit output power and the minimum/maximum values of theoutput control range specified using the LCT or PNMT.

ROI-S04051 SYSTEM DESCRIPTION

The ATPC Control System of Pasolink+ transmits the information on thereceiving level to the opposite station and controls the transmission levelof its own station in accordance with the receiving level of the oppositestation. Transmission level control can be used not only for setting thesame operation (ATPC-ATPC) between own station and opposite stationbut also for operation in combination of stations with different operation(MTPC-ATPC, ATPC-MTPC) between own station and opposite station.The station set in MTPC mode is not controlled by the information fromopposite station but is fixed in its transmitting output level.
Even if the station is set in the MTPC mode, the opposite station is likelyto be set in the ATPC mode. Therefore, setting the RX Threshold(Receiving threshold level) is required for controlling the transmissionlevel of the opposite station. Between the stations that are respectively setin the MTPC mode, however, the setting is disabled.
The following is an example of operation between stations set in MTPC-ATPC mode.
The transmitting level of station B is controlled so that the receiving levelof station A in the above figure reaches the RX Threshold set level (−50dBm) set in station A. This method is used in station A for reducing thelevel of interference to other route. As station A is set in the MTPC mode,the transmitting level is kept unchanged.
Then an example of using MTPC-ATPC is shown below. As shown in thefigure, in the master station communicating with many substations, wavesgather from substations possibly causing interferences. Therefore,substations must be set in the ATPC mode to minimize the diffraction(interference) to other routes while reducing the receiving levels fromindividual substations to the minimum. In substations, there is littlepossibility of occurring interferences; therefore, the master station is set inthe MTPC mode to permit transmission at a constant level.

The Network Management System (NMS) configuration is shown in Fig.2-6. The pasolink network management system (PNMS) is connected tothe PNMS V.11/LAN connector of the IDU located at the designatedmaintenance center while the pasolink network management terminal(PNMT) is connected to the PNMT connector on the IDU of remotestations. The PNMT/PNMS provides monitoring and control of the actualmicrowave link status and its associated Pasolink equipment. Statusinformation form and control signals to remote stations are transmittedusing one of the SC channels.
Note: This SC channel is multiplexed on the main signal forsubsequent transmission to the opposite station. If the IFloopback is executed the SC channels of the station undermaintenance will also be looped back, thereby making itimpossible to monitor or control the opposite and thesubsequent stations

2.5 Protection Switching
Protection switching is provided in the Hot-standby system.
2.5.1 Hot-standby System
Protection switching in this system is performed by the TX switches* onthe No. 1 and No. 2 channel ODUs at the transmitting end and by the HLSW** on the CTRL module of the IDU at the receiving end.
Notes: 1. * Transmit switching is actually accomplished by muting theoutput of either No.1 or No.2 channel ODUs, using a controlsignal from the IDU. For the description of switching withTX switch, refer to para. 2.5.2 (a)
2. ** For the switching configuration of HL SW on the CTRLmodule, refer to para. 2.5.2 (b).
3. The switching of Main 2Mbps data is performed by hitlessswitching, and the WS and DSC signals are not so.
When both the No. 1 and No. 2 channels are in normal operatingcondition, the 2 Mbps data signal from the associated MUX equipment aresent to the No. 1 and No. 2 channel ODUs through the No. 1 and No. 2channel IDUs. Here, either of the No. 1 or No. 2 channel signal is selectedat the TX switch on the ODU and fed to the receiving end. At the receivingend, the output data signal of the No. 1 and No. 2 channels MODEM enterthe HL SW on the CTRL module. The data signal selected by HL SW isfed to associated MUX equipment.
When the modulator alarm is detected in the MODEM or when the TX IFinput alarm, TX power alarm or APC alarm is detected in the ODU, thealarm signal is sent to the switch control logic circuit on the CTRLmodule. The switch control logic circuit produces a TX switch controlsignal for selecting the ODU that is in the normal condition. When theODU receives the TX switching control signal, the output of the ODU thatis currently active (on-line) is muted and the output of the other ODU isun-muted. The switching condition is shown on the LCT and by the TX1and TX2 STAUS indicators on the IDU.
At the receiving end, when the Reed Solomon error alarm is detected inthe MODEM of the No. 1 channel, the alarm signal is sent to the switchcontrol logic circuit on the CTRL module. The switch control logic circuitproduces a HL SW control signal that would cause the HL SW to select thedata signal from No.2 channel. The switching condition is shown on theLCT and by the RX1 and RX2 STATUS indicators on the IDU.

2.5.2 Switchover Control
The following explains the protection switching function in the HSsystem.
(a) TX SwitchingTX switching in HS system is accomplished by muting the TXoutput power of either No.1 or No.2 channel ODU. Two types ofTX switch controls are provided: automatic switching that isinitiated by detection of a failure in the transmit section of theMODEM or ODU, and manual switching that is initiated by theoperator using the LCT. TX switching, either initiated manually orautomatically, may cause a short interruption of the data.Automatic and manual TX switching have the followingoperational characteristics: • Switching Priority: 1. Manual switching
2. Automatic switching• Switching condition: Non-priority (Non-homing)
Note:In non-homing mode, the channel currently selected remainsselected even if the alarm in the previously selected channelis normalized.
(b) RX Switching RX switching in HS system is performed by the HL SW on theCTRL module.Two types of RX switch controls are provided: automaticswitching that is initiated by the quality deterioration of thereceived signal and manual switching that is initiated by theoperator using the LCT.The switching priority and switching conditions for automatic andmanual swathing are identical to those of TX switching. However,the switching condition is only valid under automatic switchingcontrol. This is because automatic switching is implemented byhardware logic and manual switching is implemented by softwarelogic. That is, automatic switching and manual switching arecompletely independent and separate operations. Thus, when theoperator reverts to automatic switching after performing manualswitching, the channel that was selected when RX switching wasunder automatic control will be re-selected by the HL SW.In automatic switching mode, the system quality is considered tobe deteriorated when the detected BER exceeds the internallypreset value (1 × 10-8 to 1 × 10-10).

3.2.1 Modulator SectionThe 2.048 Mbps signal received from the terminal equipment enters theinterface section of the CTRL module. The interface section extracts theclock component from the data signal that is in high density bipolar-3(HDB-3) format. Then the code is converted from HDB-3 to non-return-to-zero (NRZ) with this clock signal and fed to MODEM module.
The input signal from the interface section is speed-converted for radioframe and time slots are inserted. Then additional bits for the digitalservice channel (DSC), wayside(WS), orderwire(OW) and supervisory(SV) signals are inserted in the time slots. Moreover, error correction FECbits are inserted, and coded, then, string-converted to obtain the data signalrequired for modulation. The data signal converted will modulate the 340MHz IF signal, and is fed to the ODU INTFC module.
The 340 MHz IF signal received from the MODEM module is multiplexedwith the ODU power supply and control signal, etc. at the MPX section,then fed to ODU after the deterioration due to the cable between IDU-ODU is corrected.
3.2.2 Demodulator Section
At the MPX in the ODU INTFC module, the control signal is separatedfrom the 140 MHz IF signal received from the ODU. 140 MHz IF signalis fed to MODEM module after the deterioration due to cable lengthbetween ODU-IDU and the signal level are corrected.
The 140 MHz IF signal from ODU INTFC module is demodulated at thedemodulator section, then regenerated to the baseband signal composed ofthe radio frame. After the detection and correction of errors that occurredat the radio link are performed in the error correction section, radio framesynchronization is established. Then the DSC,WS, OW and SV signalsinserted in the transmitter side are extracted from the time slots. Then timeslots for additional bits are removed, and fed to the interface section.
The NRZ-coded data signal is converted to the original HDB-coded 2.048Mbps data signal and fed to terminal equipment.

3.4 Functional Operation
A block and level diagram of the ODU is shown in Fig. 3-5. Functionaloperations of the ODU are described separately for the transmitter sectionand receiver section.
3.4.1 Transmitter Section
A 340 MHz IF signal which is composed of the DC components, andcontrol signal, etc., from the IDU is separated by the multiplexer (MPX)circuit. The 340 MHz IF signal received from the IDU converts the RFsignal with a local signal generated by a synthesized local oscillator. ThisRF signal goes to antenna through the BPF which eliminates undesiredcomponents generated in the IF-RF conversion.
3.4.2 Receiver Section
First, an RF signal received through the antenna is amplified to therequired level by the RF amplifier. Afterward, an RF signal converts the140 MHz IF signal with a local signal generated by a synthesized localoscillator. The 140 MHz IF signal goes to the IDU through the MPXcircuit which combines the alarm/control signal, etc.

2.5 ODU Mounting
The procedures for mounting and demounting the ODU are describedhere. There are two types of mounting for the ODU; using the NEC hybrid(HYB) and using the Quaser HYB. The ODU should be installed in theradio station. The tools for installation are listed in Table 2-1.
Caution: How to use small and large O-rings are shown in followingtable. Two (small and large) O-rings are attached in 18-38GHz band Andrew direct mount antenna. 11/13/15 GHzband antenna does not have small O-ring (Small O-ring isnot used for Andrew direct mount antenna). If the small O-ring is used for ODU direct mount installation, a gap mayoccur between ODU and antenna for RF interface.Therefore it may happen transmit or receive level down.
Note: 11/13/15 GHz antenna for direst mount is not possible to connectthe ordinary waveguide flanges.
Notes: 1. Do not use both small O-ring and large O-ringsimultaneously.
2. Large O-ring size is different with frequency band as follows:

Apparatus :HP 3466A Digital Multimeter (or equivalent) with test leads or X0818AOW/RX LEV MonitorWrench
Step Procedure
1 At each station, when the TX power control is operated inATPC, set the TX Power Control item of SystemConfiguration to “MTPC” using the LCT.Note: In Antenna Alignment Mode, since ATPC control stops, it
is set to MTPC mode and TX power is fixed.
2 At each station, TX power is set to the value calculated bythe system design. TX power setting can be performed byMTPC TX PWR item of “Provisioning Data” using LCT (orTX power is set to 0 dB (value of MTPC TX PWR item) sothat TX power becomes the maximum),Note: The MTPC TX PWR is the item which sets up the quantity
of attenuation of transmitter power, and adjuststransmitter power with the quantity of this attenuation.

2. PRECAUTIONS
The following precautions must be carefully observed duringmaintenance.
(a) The maintenance personnel should report arrival at and departurefrom a station to the relevant station. The following are dangersand warnings to the maintenance personnel.
Warning: 1. The –43 V DC power is superimposed on the centerconductor of the coaxial cable between the IDU and theODU. Connecting a test equipment directly to thisterminal may damage it, and touching the coaxial cablecore may cause electrical shock.
2. Persons performing servicing must take necessary stepsto avoid electro-static discharge which may damage themodules on the IDU or cause error. Wear a conductivewrist strap connected to the grounded (G) jack on thefront of the equipment shelf. This will minimize staticbuild-up during servicing (see Fig. 2-1).
3. Do not disconnect IF cable between the IDU and theODU in operating condition, to avoid damaging the IDUand ODU. Do not remove/connect the IF cable with IDUpower ON. Turn IDU power OFF before reconnectingthe IF cable.
4. After turning ON the equipment, wait at least 1 minutebefore turning it OFF again. Repeatedly turning thepower ON and OFF with in a short interval may causethe IDU to fail.
5. Contact NEC before program download on the LCT isperformed. Equipment may not function correctly withimproper operation.
Caution: Be careful that top surface of the IDU is hot.
(b) During maintenance, the IDU should be set to maintenancecondition by the local craft terminal (LCT) (see Chart 2-1).
(c) To avoid service interruption, perform manual protectionswitching as shown in Chart 2-2.Note: When protection switching has been automatically
completed during a fault, keep this condition by manualprotection switching operation.
(d) When the operation of “Control” in maintenance item on LCT iscarried out, set MAINT Mode to “ON” condition first.
PRECAUTIONS ROI-S04054
2-2
(e) Information on the maintenance and the control such as TX SW,RX SW, Mute, CW, LB, etc. is released if the power is turned offor the RESET switch is pressed.
(f) Service will be interrupted instantly by pressing the RESETswitch.
(g) When the control such as TX MUTE, CW, LB, etc. is performed,set TX SW and RX SW to the same channel certainly. If it carriesout in AUTO condition, it may not operate normally.
(h) Instantaneous circuit interruption may occur when performing theTX SW manual switching operation.
(i) Before removing or installing the IDU/ODU, turn off the powerswitch on the IDU.
(j) For procedures to change the password, refer to the Appendix inthis section.
(k) After equipment start-up, allow the equipment to warm up at least30 minutes.
(l) After completing maintenance, restore all connections and manualswitch(es) to normal and confirm that all red alarm LEDs are unlit.

5. CORRECTIVE MAINTENANCE
Corrective maintenance done in the field is described in this chapter.Corrective maintenance in the field covers fault isolation, module/unitreplacement and alignment. The fault location procedures describes howto isolate unit-level faults.
Faults can be classified into those that cause deterioration of thetransmission quality and those that interrupt the service due to amalfunction of the equipment. This chapter explains the troubleshootingprocedures for equipment faults and the corresponding remedial methods.The purpose of troubleshooting malfunctioning equipment is to restart theservice by locating the faulty part and replacing it with a spare.
The faults that cause deterioration in the transmission quality are primarilyoriginated by changes occurred in the state of propagation. Therefore, if adecline in the transmission quality or similar fault takes place frequently,the link design will have to be reviewed.
During the corrective maintenance, carefully observe the precautionsgiven in chapter 2, until the alignment is completed.
5.1 Fault Location
The following 3 methods are available for checking the details of a fault:
• Checking the ALM LED Indications and LCT Indication
• Meter Readings
• Loopback.
(a) Checking the ALM LED Indications and LCT IndicationA faulty part can be located by checking the ALM LED indicationsand LCT indications. For the explanation of the ALM LEDindication and LCT indication, refer to 2.4.1 (Alarm Indication andReporting) of chapter 2 in Description section. Also refer to Chart5-1 for operations of the LCT.
CORRECTIVE MAINTENANCE ROI-S04054
5-2
(b) Meter ReadingsBased on the meter readings during periodical inspection describedin chapter 4, a faulty part can be located by checking if the readingvalues exceed the permissible ranges. Table 5-1 shows thecorrespondence between the items for which abnormal readingsare detected and the faulty parts. In the case of an abnormal BERmeasurement result, try to locate the faulty part by (c) Loopback.
(c) LoopbackWhen there is an interruption of signals, use the PDH/SDHAnalyzer and isolate the faulty part by checking the passage of the2 MB signal by loopback. Locate the fault by using the followingdiagrams.
• Fig. 5-1 – Loopback Diagram for Fault IsolationShows the section from where the signal is turned back.
• Chart 5-2 – Loopback BER Measurement
• Fig. 5-2 – BER Measurement Setup
• Chart 5-3 – Loopback Control Setting
When maintenance such as isolating a faulty portion at the occurrence offailure and revising the software are carried out, the “Control” item inMaintenance is used.
Note: Setting items displayed on the LCT depend on setting condition of“System Configuration”.
Details of “Control” item is described as follows:

ControlControl items can be selected only under maintenance mode. As this“Control” is likely to cause disconnection of signal, take care duringoperation.
• RF FrequencySets the transmitting and receiving RF frequencies.
• ATPC manual controlUsed when changing of the transmitting power is required duringATPC operation.
• TXSW manual controlControls manual switchover of the TX SW at the transmitting side inthe 1+1 Hot standby (HS) system.
• TX muteTurns off/disables the transmitter output.
• RXSW manual controlControls manual switchover of the RX SW in the 1+1 system. Theswitchover is carried out without traffic interruption. Adjustment ofthe delay time of No.1 and No.2 is automatically set.
• CWUsed for outputting a clean carrier wave (CW). Used to confirm thetransmitting output power and frequency stability.
• IF loopbackUsed for localizing equipment failure to IDU or ODU. The input2.048 MB signal from MUX is looped back at IF stage. If noabnormality is found in the signal after IF loopback, it is assumed thatthe ODU has a problem.
• Main 2M loopback (NEAR END)Used for localizing equipment failure to MUX equipment or radioequipment. The input 2.048 MB signal from MUX is looped backand then output with 2.048 MB signal. If no abnormality is found inthe signal with NEAR END loopback, it is assumed that the radioequipment (IDU or ODU) has a problem.
• Main 2M loopback (FAR END)Used for localizing equipment failure to MUX equipment or radioequipment. Signal is looped back at the IDU of the opposite station.If no abnormality is found in the signal through FAR END loopback,it is assumed that the local radio equipment (IDU or ODU) has noproblem.

• Antenna Alignment ModeThe Antenna Alignment Mode is the mode used for AntennaOrientation. This mode is used for extending the dynamic range ofthe RX LEVEL MONITOR. The output of RX LEV MON in ODUcan be enlarged and the meter indication of the OW/RX LEVMonitor can be enlarged. In this mode, since control of TX powerstops, the normal operation can not be performed.

12 Press the “5” key for setting the TX PWR and press the“Enter” key,
MTPC TX PWR sets the transmission power in MTPCoperation. If the attenuation is set to 0 dB, maximum outputpower is obtained. Setting is available in the range of −25 to0 dB. The level is not indicated in the ATPC mode.
13 Press the “ESC” key to go back to the menu shown in step 3,
14 Press the “6” key for setting the ATPC Range and press the“Enter” key,
ATPC Range sets the maximum or minimum transmissionpower during ATPC operation. If the ATPC Maximum PWRis set to 0 dB, the maximum output power is obtained. In theMTPC mode, this menu will not appear.
Note: Example of ATPC setting.Where ATPC MAXIMUM PWR of ATPC Range is setto 0 dB, ATPC MINIMUM PWR is set to -10 dB andRX Threshold to -60 dBm. In this case, if RX level issmaller than -60 dBm, monitor/control is performedwith the interval of 8 msec. RX level is monitored in 1dB step, and TX output is controlled in 1 dB step.However, a fixed hysteresis of 5 dB referred to the RXThreshold is implemented for ATPC operation.Example: If RX Threshold is set to -60 dBm, no outputcontrol is made unless the RX level goes below -60dBm or goes above -55 dBm, so that the receive level ismaintained within -60 to -55 dBm.

• Relay ConfigurationA maximum of 11 relays can be defined to provide parallelalarm outputs. The alarms that would cause RL1 to RL3 tobe triggered are pre-assigned while the alarms that wouldcause RL4 to RL11 to be triggered can be selected for eachrelay. It is also possible to define RL8 to RL11 as HK CONToutputs instead of alarm outputs as shown in the table below.If RL8 to RL11 are not assigned as HK CONT outputs, theymay be used as alarm outputs (see Table 2-2, chapter 2 inOperation section). As shown in Table 2-2 (chapter 2 inOperation section), more than one alarm may be assigned toeach relay.
RL1 to RL11 are FORM C relays. In the normal or controloff condition, the COM and NC terminals of the relays form aclosed circuit and the COM and NO terminals from an opencircuit. In the alarm or control on condition, the COM andNC terminals of the relays form an open circuit and the COMand NO terminals from a closed circuit.
