Service State Audit (#256)
This test checks the service state of the tru nk.
Country protocol 1. If the interface uses country p rotocol 1 (includes USA), the
service-state audit exec utes in all trunk service states. It q ueries the service state
on the far end and waits 2 minutes for a rep ly. If the first request times out, the
service-state audit asks ag ain. If the request times out again, it log s error 3073
and resends the request every 15 mi nutes. It places in-servic e trunks in the
MAINTENANCE/FAR-END state (outgoing calls b locked, incoming calls
accepted). Incoming calls trig ger an immediate servic e-state audit without
waiting for the end of a 15-minute c ycle.
Any other country protocol. If the interface uses some other c ountry protocol,
the service-state audit exec utes only on trunks that are in the
OUT-OF-SERVICE/FAR-END state. It asks the far-end switch to b ring 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 ag ain. 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.
