Automatic Tests for the 100D Module
Every 15 minutes, the system checks the 100D module for the following:
Initialization. The system ensures that all T1 ports are properly initialized
and placed into service. It also resolves the conflicts of different service
levels (for example, between the individual ports or for the initialization
of the ports to support features).
Error Detection. The system detects errors and takes the trunk out of
service, if appropriate. It attempts to restore the trunk and put it back
into service.
Error Recording. The system records all errors and outages in the error
logs.
Audits and Updates. The system checks the state of the T1 facilities
through audits, status checks, and error logging.
Synchronization. The system maintains proper synchronization to the
loop clock and switches to the local clock when the loop clock is not
available (for example, during a loss of signal or a blue alarm). When the
loop clock source is restored, the system switches back to the loop
clock.
