Service State Audit (#256)
As is noted in the general d escription for PRI Endpoint Port, these ports may b e
in one of several service states as defined by the ISDN-PRI Specification. This
test performs a service state aud it with the far-end terminal ad apter to ensure
that both sides agree on the se rvice state.
A PASS for this test simply means that an audit message was succes sfully
composed and sent out to the far-end terminal adap ter. The ISDN Specification
allows up to two minutes for a reply. If no reply is recei ved within that two minute
window, this switch automatically t ries once again. If that attemp t fails, an error is
logged (Error Type 3073), and the switch att empts a recovery by automati cally
retrying approximately every 15 minutes. If the port was initially in the INS
(in-service) state, it is now plac ed into the MTC/FE (maintenance state, far-end
problem) state. Until a Service State Audit attemp t is successful, no outg oing
calls are placed over this port, but inc oming calls are be ac cepted. The service
state of this port does not affec t the service state of other ports in the PRI
Endpoint. If an incoming c all that uses this port is presented while in such a state,

Result Description/Recommendation
ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
1700 ABORT Rollabout video abort. The PRI terminal adapter associated with this PRI
endpoint extension is detached from the circuit p ack. This is a normal abort
when the rollabout video feature is enabled. To complete the test on this port,
do one of the following:
1. Re-attach the disconnected PRI terminal adapter, or
2. Disable the rollabout video feature on this circuit pack by entering the
change ds1 PCSS command, and set the field Alarm when PRI
Endpoint Detached? to y.
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 Packet Interface (PKT-INT). Further information
may also be obtained by consulting the proced ures 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 pac k (UDS1-BD).
PASS The signaling link hardware is okay.
