ATM-BCH (ATM B-Channel Trunk)
Issue 4 May 2002
10-199 555-233-123
i. Error Type 3585: ISDN RESTART message received. Active calls have
been dropped.
The following Aux Data values (Error Type 3585 only) below represent the
trunk’s ISDN call state at the time Error 3585 occurred. This information
can be useful if users report dropped calls on the ISDN-PRI trunks.
j. Error Type 3841: the far-end rejected an ATM CES trunk selected by the
near-end 10 times. The ATM CES trunk may not be administered on the
far-end.
1. Get the physical name of the ATM trunk by noting the decimal
number in the Aux Data field.
2. Check administration for the named trunk on the far-end.
3. If problems persist, then busyout the ATM trunk to take it out of the
hunt group.
The WARNING alarm retires automatically whenever a called endpoint
answers an outgoing or incoming call that uses the alarmed trunk.
