Maintenance Strategy
The goal of maintenance is to isolate the trouble to one or more
replaceable units and to replace the faulty units as quickly as
possible. To help isolate the fault, check equipment in the
following order:
1. Telephones and adjuncts
2. Station wiring
3. Line/trunk and station modules
4. Processor module
5. Power supply module
6. Carrier backplane
Note: Traffic problems can result from having more than 64
personal lines or pool buttons on the system. If you have traffic
problems, check this first.
Use the maintenance program as follows:
1.
Check the error logs.
2. If the error logs indicate trouble in the processor module,
correct that problem first since it may be causing trouble in
the line/trunk and station modules.
