● M o s t R e c e n t S y s t e m E r r o r s : The ten Most Recent System Errors are recorded by the system, regardless of their level of severity. These are stored in the Most Recent System Errors log.
Error Logs
The three error logs can redisplayed via the System Administration Terminal. The data in the log is useful in diagnosing and analyzing troubles, particularly when the problem has not yet caused an alarm or when alarms cannot be retired by replacement of maintenance objects.
The error log is historical in nature. | It lists faults that have not been resolved as well as |
past alarms, and provides a profile of | system maintenance. |
Automatic Maintenance Tests
There are two kinds of maintenance testing initiated (only) by the system:
●Periodic
●Demand
Periodic tests are run by the system at fixed intervals. The tests do not affect service.
Demand tests are run by the system when it detects a condition requiring a need for testing. Demand tests are only performed when errors are detected. Maintenance personnel cannot initiate these tests.
For additional information, see AT&T System 25 Maintenance Manual.
