Service State Audit (#256)
As noted in the general desc ription for PRI endpoint port, these p orts may be 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 adap ter to ensure both
sides agree on the service s tate.
A PASS for this test simply means that an audit message was successfu lly
composed and sent out to the far-end terminal adapter. The ISDN Specific ation
allows up to 2 minutes for a reply. If no reply is receiv ed within that 2 minute
window, this switch will automatically try onc e again. If that attempt fails, an error
will be logged (Error Type 3073) and the switch will then attempt recovery by
automatically retrying ap proximately every 15 minutes. If the port w as 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 b e placed over this p ort, but incoming cal ls 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 c all that uses this port is presented while i n such a
state, a Service State Audit attempt will immed iately be attempted (that is, the
switch will not wait for the 15-minute cyc le, but will instead try to recove r
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 c ircuit pack. This is a normal ab ort
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.
