Service State Audit (#256)
As is noted in the general description for PRI Endpoint Port, these ports may be
in one of several service states as defined by the ISDN-PRI Specification. This
test performs a service state audit with the far-end terminal adapter to ensure
that both sides agree on the service state.
A PASS for this test simply means that an audit message was successfully
composed and sent out to the far-end terminal adapter. The ISDN Specification
allows up to two minutes for a reply. If no reply is received within that two minute
window, this switch automatically tries once again. If that attempt fails, an error is
logged (Error Type 3073), and the switch attempts a recovery by automatically
retrying approximately every 15 minutes. If the port was initially in the INS
(in-service) state, it is now placed into the MTC/FE (maintenance state, far-end
problem) state. Until a Service State Audit attempt is successful, no outgoing
calls are placed over this port, but incoming calls are be accepted. The service
state of this port does not affect the service state of other ports in the PRI
Endpoint. If an incoming call that uses this port is presented while in such a state,
a Service State Audit attempt is immediately attempted (that is, the switch does
not wait for the 15 minute cycle, but instead tries to recover immediately). To
investigate the status of this PRI Endpoint Port, issue the status pri-endpoint
<extension> command.
4 FAIL There is a problem with the Signaling Channel and/or with the Processor
Interface Link.
1. Consult the procedure for the ISDN-PRI Signaling Group (ISDN-GRP)
and/or the procedures for Processor Interface Link (PI-LINK). Further
information may also be obtained by consulting the procedures for the
ISDN-PRI Signaling Channel (ISDN-LNK).
8 FAIL There is a problem with the UDS1 interface circuit pack.
1. Consult the procedures for UDS1 interface circuit pack (UDS1-BD).
PASS The signaling link hardware is okay.
