ISDN-TRK (DS1 ISDN Trunk)
Issue 4 May 2002 10-987 555-233-123
l. An ISDN trunk selected by the near-end has been rejected 10 times by the
far-end without a successful call. This may indicate a service state
mismatch between the near-end and far-end for this trunk that is effecting
the end user (that is, customer receives unexpected intercept tones when
accessing ISDN trunks). This may indicate that the ISDN trunk is not
administered on the far-end.
The Aux field contains the physical name of the ISDN trunk in decimal.
Then, verify that the far-end has this trunk administered. If problems
persist, then busy-out the ISDN trunk to take it out of the hunt group.
The Warning alarm will be retired automatically whenever an outgoing or
incoming call that uses this trunk is answered by the called endpoint. If
problems persist, then busy-out the ISDN trunk to take it out of the hunt
group.
