2. PRECAUTION The maintenance personnel should report arrival and departure from a station to the relevant station. The following precaution must be carefully observed during maintenance. Warning 1. The -48V DC power is superimposed on the center conductor of the coaxial cable between the IDU and the ODU. Connecting test equipment directly to this terminal may damage it and touching the coaxial cable core may cause electrical shock. 2. Persons performing maintenance must take necessary steps to avoid Electrostatic Discharge (ESD) which may damage the cards on the IDU or cause error. Wear a conductive wrist strap connected to the grounded (G) jack on the front of the equipment shelf. This will minimize static build-up during maintenance. 3. Turn off the "ODU PWR" switch on the IDU before connecting/disconnecting the IF cable to avoid the equipment damaged. 4. After turning ON the equipment, wait at least 1 minute before turning it OFF again. Repeatedly turning the power ON and OFF within a short interval may cause the equipment damaged. 5. Do not allow open or short circuit ODU TX output with the TX power on conditions. Perform the TX Mute control in the Maintenance mode or turn the “ODU PWR” switch off at the IDU before disconnecting cable or feeder from the ODU TX output. 6. Contact NEC before program download on the LCT is performed. Equipment may not function correctly with improper operation.
Caution 1. In a system using the optical STM-1 INTFC, do not stare at the laser beam or look at it directly with optical instruments. Otherwise, it may hurt your eyes (Class 1 laser product). 2. The top surface of the IDU above MODEM is hot in operation. 3. When replacing the IDU, turn off the “ODU PWR” switch and disconnected all cables. 4. During maintenance, the IDU should be set to maintenance On by the LCT. 5. To prevent traffic interruption, under the maintenance, perform TX/RX SW manual switching in 1+1 system.

Precaution
6. While the CPU is initialized by the CPU RESET switch, alarm(s) status is reset to normal. After initialized, the alarm information is properly provided through relay contacts. 7. Information on the maintenance and the control such as Mute, CW, LB, etc. is released if the power is turned off. 8. If each setup item of NE SETUP or SYSTEM OPERATION is changed during operation, traffic will be momentarily interrupted. 9. When the TX SW is activated, momentary traffic interruption may occur. 10. After completing maintenance, restore all connections, manual control settings to normal and confirm that all alarm LEDs are unlit. 11. After equipment start-up, allow the equipment to warm up at least 30 minutes.

5. CORRECTIVE MAINTENANCE Corrective maintenance done in the field is described in this chapter. Corrective maintenance in the field covers fault isolation, card/unit replacement and alignment. The fault location procedures describe how to isolate card-level/unit-level faults. Faults can be classified in to those that cause deterioration of the transmission quality and those that interrupt the traffic due to a malfunction of the equipment. This chapter explains the troubleshooting procedures for equipment faults and the corresponding remedial methods. The purpose of troubleshooting malfunctioning equipment is to restart the service by locating the faulty part and replacing it with a spare. The faults that cause deterioration quality are primarily originated by changes occurred in the state of propagation. Therefore, if a decline in the transmission quality or similar fakes place frequently, the link design will have to be reviewed. During the corrective maintenance, carefully observe the precautions given in Chapter2, until the alignment is completed.

5.1 Alarm/Status When an alarm event has occurred, at first, check alarm indication on the front of the IDU. Continuously, connect the PC to the LOCAL jack on the LCT port mounted on the IDU and check alarm/status indication. A faulty part can be located by checking the alarm LED indications and LCT Alarm indications. Alarm Report When an alarm is detected, alarm notification is made to the user by lighting up the LEDs on the rack, and reporting the alarm to user interface. The alarm notification is also made to the user by an Office alarm, such as the station alarm bell and lamps.
ALARM LED indication LED at the front of the rack lights up/turn off when alarm is generated/cleared to report the alarm to the user. iPASOLINK 400 Main shelf

5.1.1 Alarm Management
The alarm severity of each failure is indicated by the following alarm level and alarm class. Alarm classes can be modified. Modification is done by Alarm Severity Setting. 5.1.1.1 Alarm Class Critical (CR) : The Critical severity level indicates that a service affecting condition has occurred and an immediate corrective action is required. Such a severity can be reported, for example, when a managed object becomes totally out of service and its capability must be restored. Major (MJ): The Major severity level indicates that a service affecting condition has developed and an urgent corrective action is required. Such a severity can be reported, for example, when there is a severe degradation in the capability of the managed object and its full capability must be restored. Minor (MN): The Minor severity level indicates the existence of a non-service affecting fault condition and that corrective action should be taken in order to prevent a more serious (for example, service affecting) fault. Such a severity can be reported, for example, when the detected alarm condition is not currently degrading the capacity of the managed object. Warning (WR): The Warning severity level indicates the detection of a potential or impending service affecting fault, before any significant effects have been felt. Action should be taken to further diagnose (if necessary) and correct the problem in order to prevent it from becoming a more serious service affecting fault.

6.2.3 Radio Control There are several maintenance control items that can be set during Maintenance Mode. The function of each control is as follows (These windows are not available when MAINT is in OFF. Switch to Maintenance mode first is displayed): ATPC Manual Control If TX Power Control Mode is selected to ATPC Mode, execute temporally fix control to transmit POWER. Select the value range described in ( ) of ATPC Range that located in the Provisioning Menu (MODEM Function setting -> TX Power Setting) for Transmit POWER. ATPC Manual Control can be selected from either Auto or Manual. If transmit POWER requires to temporally fix control, select Manual then select fixed value (it will be fixed until Auto is selected). Note: ATPC Manual Control is not effective if MTPC Mode is selected. TX Mute Control Despite the equipment configuration setting, forcing the “TX Mute Control” to ON will stop the transmit power of the ODU. If Mute Control is set to OFF, it will cancel the Mute control. Notes 1
If Mute Control is set to OFF and Mute OFF does not work due to uncontrollable factors, Mute status will remain ON.
2. In case of 1+1 Hot Standby configuration, the Mute OFF control does not mute both lines. Moreover, when force Mute is controlled in No.1/No.2, Maintenance Mode cannot set to OFF. 3. When TX Mute is controlled by a remote control, the setting of the automatic restoration time is possible. Therefore, TX Mute Release Time should be set. 4. TX Mute Release Time is set together with TX Mute Control by the item that becomes effective only when TX Mute Control is done from a higher-level device.
CW Control CW (no transmission modulation) is controlled. It is used when the frequency is measured with a frequency counter and when spurious one is checked. If you perform the CW control over a pre-made Mute ON, execute CW ON/OFF

after Mute OFF. At this time, when there is a factor that the CW control is not turned ON it becomes CW control error. In addition, in case of remote connection and operated Control CW, it may not be able to recover again. CW Control will restore automatically according to the TX Mute Release Time parameter. TX Modulation Manual Control The flat rate of the transmission modulation method of the control station in the AMR mode is temporarily managed. The modulation method can be set according to the target device regardless of the AMR Range setting. Under the 1+0 configuration, each Slot#/Slot# is individually controlled. This control is done by exchanging request/answer of the control between local/remote stations as well as LB2. When the TX Modulation Manual Control setting is returned from Manual to Auto, the fixed modulation method is returned to QPSK. 6.2.3.1
ATPC Manual Control Performing this function (Manual Control) sets the Maintenance Mode to ON. However, in case of Auto setting and if Maintenance Mode is set to OFF, it will cancel the “auto setting”.

6.2.5 Cluster Alarm Setting By mounting optional card of AUX, iPASOLINK is available to use Alarm input/output function port for sub-signal of Cluster Alarm and House Keeping. When House Keeping input at own station is detected, Cluster Alarm will transmit to the opposite station by setting up the bit of Cluster ALM input (output toward to wireless) When any changes for Cluster ALM output (input toward to wireless) is detected after Cluster Alarm signal was received by equipment in the opposite station, the equipment in the opposite station will be set-up bit for House Keeping output control then Relay output (RL) will be executing. After receiving a Cluster Alarm signal from the opposite station and another Cluster Alarm is input (output to the direction of the radio), a setup is performed, and Cluster Alarm signal is sent out to an opposite office. It is possible to transmit the Cluster Alarm signal. HK IN 1 to 6 (External input functions, cluster alarm, house keeping input port)

(a) House Keeping Input Port House Keeping external input port provides six port, four of six ports are used by both Cluster Alarm and House Keeping and each port is required to select Alarm function. When an external input port is selected by HKIN, the change of HKIN is detected then the change is reported to upper level. (b) Cluster Alarm Input Port When 1 to 4 external input ports are selected as a Cluster Alarm input, F/W executes to change the signal of HKIN1-4 into Cluster Alarm signal in wireless frame then output the signal toward to opposite side of wireless. In addition, any Modems are available to output the Cluster Alarm input signal.
RL OUT 1 to 6 (External output functions, cluster alarm, house keeping output port) (a) House Keeping Output Port House Keeping output port provides six port, four of six port are used by both Cluster Alarm and House Keeping and each port (HK1-4) required to set up individually from F/W to FPGA. Set up to OK or not OK for each item (parallel alarm required to set up for each alarm items), execute port output if over one alarm at specified item is detected. H/W control output port for other 2 port. (RL1, RL2 port will be fixed for parallel alarm output by H/W.) (b) Cluster Alarm Output Port When House Keeping output ports 1 to 4 are selected as a Cluster Alarm output, any Cluster Alarm detected from the radio side is outputted to any output port. Cluster Alarm output 1 to 4 signals are selected after the incoming signals of a MODEM under redundant system, and the arbitrary Cluster Alarm is output to the radio port of CH unit. In Cluster Alarm, it outputs and inputs to two or more MODEM(s) or it has a through control facility, the signal from MODEM (SW GRP unit) is chosen per Cluster port, it is possible to MODEM (SW GRP unit) to carry out an output setup.
