Service State Audit (#256)
As 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 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 2 minutes for a reply. If no reply is received within that 2 minute
window, this switch will automatically try once again. If that attempt fails, an error
will be logged (Error Type 3073) and the switch will then attempt recovery by
automatically retrying approximately every 15 minutes. If the port was initially in
the INS (in-service) state, it will now be placed in the MTC/FE (maintenance state,
far-end problem) state. Until a Service State Audit attempt is successful, no
outgoing calls will be placed over this port, but incoming calls will 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 will immediately be attempted (that is, the
switch will not wait for the 15-minute cycle, but will instead try to recover
immediately). To investigate the status of this PRI endpoint port, issue the status
pri-endpoint extension command.
1700 ABORT Rollabout video abort. The PRI terminal adapter associated with this PRI
endpoint extension is detached from the circuit pack. This is a normal abort
when the rollabout video feature is enabled.
1. Either reconnect the disconnected PRI terminal adapter or disable the
rollabout video feature on this circuit pack. To do the latter, enter change
ds1 UUCSS and set the field labeled ‘‘Alarm when PRI Endpoint
Detached?’’ to ‘‘y.’’
4 FAIL There is a problem with the Signaling Channel and/or with the System Link.
1. Consult procedures for the ISDN-GRP and SYS-LINK. See also ISDN-LNK
for useful information.
8 FAIL There is a problem with the UDS1 interface circuit pack.
1. Consult procedures for UDS1-BD.
PASS The signaling link hardware is OK.
