Signaling Link State Check Test (#255)
As noted in the preceding general description, operation of the PRI endpoint port depends on
the health of the UDS1 interface circuit pack and System Link for proper operation. This test
checks the status of those critical elements.
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

Description / Recommendation
ABRT Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
1700 ABRT 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 location and set the Alarm when PRI Endpoint
Detached? field 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.
