was initially in service, it is placed in the maintenance/far-end state. No outgoing calls will be
placed over this trunk, but incoming calls will be accepted. If an incoming call is presented with
the trunk in such a state, a Service State Audit is immediately attempted (the switch does not
wait for the 15-minute cycle, but tries to recover immediately).
For interfaces not using country protocol 1, the Service State Audit executes only if the trunk is
in the out-of-service/far-end state. A message is sent to the far-end switch to attempt to bring
the trunk back into the in-service state. A PASS for this test simply means that the message has
been successfully sent. Two minutes are allowed for a reply. If no reply is received within that
2-minute window, the message is sent out again. If again no response is received within two
minutes, the trunk remains in the out-of-service/far-end state. The switch will attempt another
Service State Audit after an hour has passed.
To investigate the service state of the DS1 ISDN Trunk, enter the status trunk grp#/mem#
