Automatic Tests for the 100D, 100DCD, and 100R
INA Modules
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
I
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.
I
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.
I
Audits and Updates. The system checks the state of the T1 facilities through audits, status
I
checks, and error logging.
Synchronization. The system maintains proper synchronization to the loop clock and
I
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.
