Common Maintenance Methods

Some methods need to be adopted to locate faults during daily
maintenance. The common maintenance methods are as follows:
1. Alarm and operation log view
Alarm and operation log view is the first method to be adopted when a
fault is detected by maintenance personnel. It is implemented through
the alarm management and operation log view interface of the BSS
operation & maintenance subsystem OMCR.
Through the alarm management interface, we can observe and analyze
alarm messages reported from each NE such as the current alarm,
history alarm and general notification. In this way, we can detect any
fault during network running in time and then locate, isolate and
remove it.
By viewing operation logs in user management, we can investigate
modifications on system parameters, locate the relevant responsible
terminal and operator as well as detect faults caused by individual
operations in time.
