ISDN-TRK (DS1 ISDN Trunk)
Issue 1 June 2005
1463
 
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# 
command.
