IF jumper IF cable
IF Cable
� Three types of IF cable in OptiX RTN 600:
� IF jumper: connection between IDU and other IF cable.
� 1/2 inch and RG-8U cable: connection between ODU and IF jumper.
� RG-8U cable is used for the distance less than 180 meter.
� 1/2 inch cable is used for the distance between 180m and 300m.
Copyright © 2009 Huawei Technologies Co., Ltd. All rights reserved.
ODU
� Outdoor unit (ODU) realizes the
mutual conversion between IF
analog signal and RF signal.
� ODU is irrelevant to the microwave
transmission capacity.
� An ODU in OptiX RTN 600 can
support capacity from 4 E1s to one
STM-1.

Common Methods of Fault Locating
1. Evaluate the whole network situation.
2. Locate the faulty point preliminarily based on the collected data.
3. Cause no negative effect on normal services
4. Depend on the NMS
UniversalAlarm and
performance analysis
1. Independent of alarm and performance event analysis
2. Rapid and effective
Locate the fault to a single station or board
Loopback
1. Convenient
2. Require spare parts/equipment.
3. Applied with other methods
Locate the fault to a board or isolate external faults
Replacement
1. Can find the fault cause.
2. Fault locating time is longer.
3. Depend on the NMS
Locate the fault to a single station or board
Configuration data analysis
1. Have a high risk.
2. Depend on the NMSLocate the fault to a board
Configuration modification
1. A general method with high accuracy
2. Have certain requirements for the meters.
3. Applied with other methods
Isolate external faults and resolve interconnectivity
problem
Test with instruments
1. Fast fault handling
2. High probability of mistake
3. Need experience accumulation.

Inconsistent working modes or

at the local and peer ends?
Yes
No
No
No
MW_RDI:
When this alarm is reported, it means that the link is faulty and
consequently the peer end
receives error bits.
MW_LOF:
The performance of the microwave link deteriorates.
The receive function of the local end fails.
The working modes of the ODUs in the local and
peer ends are different.
The working efficiency of the ODUs in the local and peer ends are different.
HUAWEI TECHNOLOGIES CO., LTD. All rights
reserved
Bit Errors
The MW_RDI and MW_LOF alarms are related to the link performance
deterioration
a new link is created and the frequency interference occurs
between the new and existing links
After modify the receive and transmit powers of the ODUs at the local and
peer ends, the problem is solved.
� Handling process
Guess: other company
creates a new microwave hop and the
new microwave hop shares the site with
Huawei.
