MAINTENANCE/FAR-END state (outgoing calls blocked , incoming calls
accepted). In coming 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 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 ag ain. If the request times out again, it
leaves the trunk in the OUT-OF -S ERVICE /FAR-END st ate and tries again in 1 hour.
