Service State Audit (#256)
This test checks the service state of the trunk.
Country protocol 1. If the interface uses country protocol 1 (includes USA), the
service-state audit executes in all trunk service states. It queries the service state
on the far end and waits 2 minutes for a reply. If the first request times out, the
service-state audit asks again. If the request times out again, it logs error 3073
and resends the request every 15 minutes. It places in-service trunks in the
MAINTENANCE/FAR-END state (outgoing calls blocked, incoming calls
accepted). Incoming calls trigger an immediate service-state audit without waiting
for the end of a 15-minute cycle.
Any other country protocol. If the interface uses some other country protocol, the
service-state audit executes only on trunks that are in the
OUT-OF-SERVICE/FAR-END state. It asks the far-end switch to bring the trunk
back into the IN-SERVICE state and waits 2 minutes for a reply. If the first request
times out, the service-state audit asks again. If the request times out again, it
leaves the trunk in the OUT-OF-SERVICE/FAR-END state and tries again in 1
hour.
NOTE:
PASS for this test only means that a message to the far-end was
successfully sent.
To check the service state of the ATM-BCH trunk, run status trunk grp#/mbr#.
