Digital line maintenance interacts with digital line media module (MG-DCP) maintenance. The health of the media module can affect the results of DIG-LINE testing. Keep this in mind when investigating digital-line problems.
It is sometimes important to know the service state of a station. These service states apply to digital-line stations:
Out-of-service state |
The port, and thus the station, have been removed from service. The busyout command puts the port in the out-of-service state. |
Ready-for-service state |
The port on the media module has been put into service, but the voice terminal has not yet established signaling communications with the port. |
In-service state |
The voice terminal has established signaling communications with the port, and the system is ready to process calls to and from that station. A terminal in the ready-for-service state will progress to the in-service state if it is functioning normally. It can also be forced into the in-service state by going off-hook. |
