WARNING
1. After turning ON the equipment, wait at least 10 secondsbefore 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.

• 38 GHz Band: 37.0 to 40.0 GHz
For details, refer to the Appendix in Description section.
The actual TX frequency of the ODU should be within the TX radiofrequency band of the ODU and is entered using the local craft terminal(LCT). The corresponding RX frequency is automatically set after the TXfrequency is entered. For 6/7/8 GHz band ODU, the frequency settingshould be the same as that written on the ODU label. For 11-38 GHz bandODU, transmitting frequency for 32 QAM system should be enteredbetween “Start” frequency + 21 MHz and “Stop” frequency − 21 MHzdisplayed on LCT, and 128 QAM system should be entered between“Start” frequency + 12 MHz and “Stop” frequency − 12 MHz displayed onLCT.

2.4.1 Alarm Indication and Reporting
Alarm indication and reporting functions are provided with the IDU.Summary alarm indicators using LED’s are provided for the ODU andIDU, separately. ODU alarms detected by the alarm detection circuit inthe ODU are sent to the CTRL module in the IDU. This causes the ODUalarm indicator on the IDU front panel to turn on. Similarly, any IDUrelated alarms that are detected will cause the IDU alarm indicator on theIDU front panel to turn on. External reporting of alarms is also providedthrough closed relay contacts accessible via the front panel interface (seeTable 2-3).
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 module,polls 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 Laser Shutdown Control (OPT INTFC Module)
The IDU is provided with the automatic laser shutdown (ALS) functionthat can be enabled or disabled. If the ALS function is enabled, the laseroutput is periodically turned ON and OFF when the optical cable carryingthe STM-1 signal is disconnected inadvertently, or internationally duringmaintenance. If the ALS function is disabled, the laser output is alwaysON even if the optical cable is disconnected.
Fig. 2-4 shows a block diagram of the ALS function. If a fault occurs atpoint A and the absence of the optical input signal in the RX 2 lasts for 550±50 msec (STM-1 LOS alarm condition), the optical signal bound for theRX 1 (MUX equipment) from the TX 2 (OPT INTFC module) isinterrupted by a control signal generated inside the OPT INTFC module.The MUX equipment detects the loss of signal at RX1 and the ALSfunction in the MUX will, subsequently, turn off the laser output of TX1.When the fault at point A is cleared the system can be restored bycontrolling the laser output of TX2 through one of the following modes:
• Automatic control
• Manual restart (2 sec.) control
• Manual restart (90 sec.) control
(a) Automatic ControlWhen 60, 180 or 300 (selectable) sec. have elapsed after theoptical signal entering RX 2 is cut off, the IDU emits laser signalfrom TX 2 to RX 1 for 2 sec. This would then cause the laseroutput of TX1 to turn on. If, at this time, the fault at point A hasbeen cleared, the ALS function will be released and the operationwill return to normal.
(b) Manual Restart (2 sec.) ControlUpon receiving a command signal for manual restart from the LCTor the pasolink network management terminal (PNMT) while theoptical input signal to the RX 2 is off, the IDU emits the lasersignal from the TX 2 to the RX 1 for 2 ±0.25 sec. This would thencause the laser output of TX1 to turn on. If, at this time, the fault atpoint A has been cleared, the ALS function will be released andthe operation will return to normal (it returns to automaticcondition).
SYSTEM DESCRIPTION ROI-S03832
2-24
(c) Manual Restart (90 sec.) ControlUpon receiving a command signal for manual restart for test fromthe LCT or the PNMT while the optical input signal to the RX 2 isoff, the IDU emits the laser signal from the TX 2 to the RX 1 for 90±10 sec. This would then cause the laser output of TX1 to turn on.If, at this time, the fault at point A has been recovered, the ALSfunction will be released and the operation will return to normal (itreturns to automatic condition).
Fig. 2-4 ALS System Functional Block Diagram
2.4.4 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

A functional block diagram of the ATPC operation is shown in Fig.2-5. 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 in 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 level by lowering or raising the TX output power ofthe opposite station, is generated by the MODEM module throughthe CPU circuit. This control signal is based on the result ofcomparison between the current receiver input level and the presetreceiving threshold level. Using RFCOH bits, this control signal issent to the opposite station 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.

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.

3.2.1 Modulator Section
Electrical InterfaceThe STM-1 signal received from terminal equipment enters the STM-1interface section of the 150M INTFC module. The STM-1 interfacesection first extracts the clock component from the STM-1 data that is inCoded Mark Inversion (CMI) code, and then the CMI-coded data signal isconverted to Non-Return-to-Zero (NRZ) code using the extracted clocksignal. After STM-1 frame synchronization is established in the framesynchronization section, the RSOH bytes are extracted and the B1 parityerrors are detected for performance monitoring. Then, the B1 parity isrecalculated for performance monitoring of the radio link. This B1 parityis sent to the MODEM module for insertion in the RSOH portion of theSTM-1 frame.
Optical InterfaceThe optical STM-1 signal received from terminal equipment enters theSTM-1 interface section of the OPT INTFC module. The STM-1 interfacesection converts the optical signal to an electrical signal and extracts theclock signal from the data stream. After STM-1 frame synchronization isestablished in the frame synchronization section, the RSOH bytes areextracted and the B1 parity errors are detected for performancemonitoring. Then, the B1 parity is recalculated for performancemonitoring of the radio link. This B1 parity is sent to the MODEMmodule for insertion in the RSOH portion of the STM-1 frame.
Input data signal from 150M INTFC/OPT INTFC module is speedconverted to give room for the redundant bits such as radio framecomplementary overhead (RFCOH) and forward error correction (FEC),which are to be added in the next stages. Then the RFCOH bits areinserted to the pre allocated slots. RFCOH is a signal multiplexed withOW, 64k SC and SV for monitor/control. Error correction FEC bits for theradio link are inserted, and coded, then string-converted to obtain datastream required for modulation. Data signal string-modulated willmodulate the 340 MHz IF signal, then fed to the ODU INTFC module.
340 MHz IF signal received from MODEM module is equalized tocompensate for the distortion in the IDU-ODU cable and then multiplexedwith ODU driving power supply, control signal etc., at MPX section,before feeding to the ODU.
3.2.2 Demodulator Section
The 140 MHz IF signal and the control signal that are contained in thecomposite signal received from the ODU are separated at the MPX sectionof the ODU INTFC module. After correcting for characteristicdeterioration and signal level degradation that may have been introducedby the cable connecting the IDU and ODU, the 140 MHz IF signal is fed tothe MODEM module.
SUBSYSTEM DESCRIPTION ROI-S03832
3-6
The 140 MHz IF signal from the ODU INTFC module is demodulated atthe demodulator section, then regenerates the baseband signal composedof the radio frame. After the radio frame synchronization is established,detection and correction of errors that may have occurred at the radio linkare performed in the error correction section. The STM-1 signal isregenerated after separating the RFCOH bits and then fed to the 150MINTFC/OPT INTFC module.
Electrical InterfaceAfter STM-1 frame synchronization is established in the data signal fromthe MODEM module, the RSOH byte is extracted and the B1 parity errorfor performance monitoring of the radio link is detected. Then, the B1parity is re-calculated and RSOH bytes are inserted. At the STM-1interface section, the NRZ code is converted to CMI code and then fed tothe 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 is converted to anRF signal using a local signal generated by a synthesized local oscillator.This RF signal is then sent to the antenna through the BPF whicheliminates undesired components generated in the IF-RF conversion.
3.4.2 Receiver Section
First the RF signal received through the antenna is amplified to therequired level by the RF amplifier. Afterward the signal is converted tothe 140 MHz IF signal by mixing with a local signal generated by asynthesized local oscillator. Then the 140 MHz IF signal is sent to the IDUthrough the MPX circuit whom it is combined with the alarm/controlsignal, etc.

2.4 ODU Mounting
The procedures for mounting and demounting the ODU are describedhere. There are two types of mounting for the antenna direct mountingtype and waveguide connecting type. The ODU should be installed in theradio station. The tools for installation are listed in Table 2-1.
Note: In 18-38GHz band 2 O-rings are included in the Andrew directmount antenna kit; the large one is used for ODU mounting andsmall one is used for waveguide connection only. The 13 and15 GHz band antenna doesn’t have a small O-ring. (The small O-ring isn’t used for Andrew direct mount antenna.)If the small O-ring is used for ODU direct mount installation,there will be a gap between the ODU and antenna RF interfacebecause of a small tab at the ODU RF interface which interfereswith the small O-ring. This may cause the transmit or receivesignal level to decrease.

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.

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 quantityof attenuation of transmitter power, and adjuststransmission power with the quantity of this attenuation.

ROI-S03835 PRECAUTIONS
2-1
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 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 the IF cable between the IDU and theODU in operating condition, to avoid damaging the IDUand ODU. Do not remove/connect the IF cable with theIDU power ON, turn the IDU power OFF beforeconnecting the IF cable.
4. Wait for 10 seconds or more to turn OFF the powerswitch of the IDU again after turning it ON. Do notrepeat turning ON/OFF the power in a short time, or theIDU may fail.
Caution: 1. In a system using the OPT INTFC module, do not stareat the laser beam or look at it directly with opticalinstruments. Otherwise, it may hurt your eyes (Class 1Laser Product).
2. 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) First set the MAINT mode to “ON” before selecting the otheritems on the LCT maintenance menu.
(d) While the CPU is initialized by pressing the RESET switch,alarm(s) is in normal condition. After initialization, the alarminformation is properly provided through relay contacts.
(e) Information on the maintenance and the control such as Mute,CW, LB, etc. is released if the power is turned off or the RESETswitch is pressed.
PRECAUTIONS ROI-S03835
2-2
(f) Before removing or installing the IDU/ODU, turn off the powerswitch on the IDU.
(g) For procedures to change the password, refer to the Appendix inthis section.
(h) After equipment start-up, allow the equipment to warm up at least30 minutes.
(i) 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 module-level/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 to check 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 LEDindications and LCT indications. For the explanation of the ALMLED indication and LCT indication, refer to 2.4.1 (AlarmIndication and Reporting) of chapter 2 in Description section.Also refer to Chart 5-1 for operations of the LCT.
(b) Meter ReadingsBased on the meter readings during periodical inspectiondescribed in chapter 4, a faulty part can be located by checking ifthe reading values exceed the permissible ranges. Table 5-1shows the correspondence between the items for which abnormalreadings are detected and the faulty parts. In the case of anabnormal BER measurement result among the meter readingitems, try to locate the faulty part by (c) Loopback.
CORRECTIVE MAINTENANCE ROI-S03835
5-2
(c) LoopbackWhen there is an interruption of signals, use the STM/SONETanalyzers and isolate the faulty part by checking the passage of theSTM-1 signal by loopback. Locate the fault by using thefollowing diagrams.
• Fig. 5-1 – Loopback Diagram for Fault IsolationShows the part from where the signal is to be turned back.
• Chart 5-2 – Loopback BER Measurement
• Fig. 5-2 – BER Measurement Setup
• Chart 5-3 – Loopback Control Setting
When the maintenance such as isolating a faulty portion at the occurrenceof failure and revising the software are carried out, “Control” item inMaintenance is used.
Note: Indication items on LCT display should be changed according tosystem 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.
• TX muteTurns off/disables the transmitter output.
• CWUsed for outputting a clean carrier wave (CW). Used to confirm thetransmitting output power and frequency stability.
• IF loopbackUsed for localizing equipment failure to ODU or IDU. The inputSTM-1 signal from MUX is looped back at IF stage. If noabnormality is found in the signal after IF loopback, it is assumedthat the ODU has a problem.
• STM-1 loopback (NEAR END)User for localizing equipment failure to MUX equipment or radioequipment. The input STM-1 signal from MUX is looped back andthen output with STM-1 signal. If no abnormality is found in thesignal with NEAR END loopback, it is assumed that the radioequipment (IDU or ODU) has a problem.
• STM-1 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.
• ALS manual restartSets the duration that the laser is emitted when ALS manual restartfor test is performed.
CORRECTIVE MAINTENANCE ROI-S03835

• 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.

• 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 forma closed 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.
