ISDN-TRK (DS1 ISDN Trunk)

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 and far ends for this trunk that is affecting the

end user (that is, customer receives unexpected intercept tones when

accessing ISDN trunks). This may indicate that the ISDN trunk is not

administered at 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.

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 busyout the ISDN trunk to take it out of the hunt
