1. GENERAL

This section provides information on routine and corrective maintenance for the iPASOLINK used for 6 to 42 GHz PDH/SDH/Packet digital radio system.

This information includes followings with its instructions and procedures:

Precautions for maintenance Materials for maintenance (test sets and accessories) Performing routine maintenance tasks Performing corrective maintenance tasks

General

Precaution


2-1

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 centre 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 interface, 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


2-2

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 in 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.

Precaution


2-3

Straight Type

Tighten the TNC-male connector of IF cable to the IDU with engage connector nut only using fingers and holding the cable with another hand.

L-angle Type

Tighten the engage connector nut only for the L-angle connector also. (Tightening Torque: 0.3 to 0.5 N-m (3 to 5kg. Cm))

If rotate other parts of the L-angle connector as illustrated left, it can cause connector damage.

6. CORRECTIVE MAINTENANCE

Corrective maintenance to be 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.



6-2

6.1 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/turns off when alarm is generated/cleared to report the alarm to the user.

Figure 6-1 LED Location

Web-LCT indication

The alarm LED indications faulty part can be located by checking the ALM LED indicators and Web-LCT Alarm indications.



6-3

Figure 6-2 Active Status (Current Status) Window

Meter Reading

Based on the meter readings during periodical inspection with LCT in Chapter 5, a faulty part can be located by checking if the reading values exceed the permissible ranges.

Loopback

In case of an abnormal BER measurement result among the meter reading items, try to distinguish the faulty part by Loopback procedure.

6.1.1 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.

6.1.1.1 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.

7.1 Loopback When there is an interruption of signals, use the SDH/SONET/PDH analyzers and isolate the faulty section by checking the traffic signal by loopback. Setup the test equipment according to the following diagrams for PDH or SDH configuration.

The facility loopback is toward the baseband interface direction and terminal loopback is toward the CS card direction. They are performed at the STM-1/4 (SDH) or E1 (PDH) interfaces. (Note 1, 2)

When executing the loopback control, set Maintenance Mode to ON and do not release Maintenance Modes while controlling loopback.

7.1.1 IF Loopback Execute the MODEM Loopback control for checking the incoming of traffic signal inside MODEM interface (The traffic signal from E1 interfaces to wireless direction).

Control Items


7-3

Notes

1. Turn on the TX Mute Control before executing IF Loopback. While IF Loopback is being executed, the TX INPUT ALM of ODU will occur because the MOD output is determinate. So, the MOD ALM and TX INPUT ALM will be masked while IF Loopback is executed.

2. The MOD ALM and TX INPUT ALM will be un-masked as soon as the IF Loopback is off.

3. If the remote control connected at opposite side, the remote control will be disconnect while the IF Loopback is executed and does not restore in default. So, it is necessary to set the IF Loopback Release Time to release IF Loopback automatically before executing the IF Loopback.
