Service State Audit (#256)
These trunks may be in one of several service states. This test p erforms a
Service State Audit with the far-end switch.
For interfaces using country p rotocol 1 (including US), the Service State Audit
executes in all trunk service state s. A message is sent to the far-end switc h to
ensure that both sides agree on the servic e state. A PASS for this test simply
means that the message has been suc cessfully sent. Two minutes are allowed
for a reply. If no reply is received within that 2 min ute window, the message is
sent out again. If that attempt fails, an error is log ged (Error Type 3073) and the
switch then attempts another Service State Aud it every 15 minutes. If the trunk
was initially INS (in-service), it is then plac ed in the MTC/FE (maintenance state,
far-end problem) state. No outg oing calls are pl aced over this trunk, but
incoming calls are ac cepted. If an inc oming call is presente d while in such a
state, a Service State Audit attempt is immed iately attempted (that is, the switc h
does not wait for the 15-minute cyc le, but tries to recover immedi ately).
