Error Type 3585 appears when the switch receives an ISDN RESTART message for an ISDN
trunk. Calls are cleared with the RESTART message. Therefore, this Error Type may be
associated with a dropped call report from a user.
The following Aux Data values for Error Type 3585 represent the trunk’s ISDN call state at the
time the unexpected request to restart the channel was received from the remote switch. This
information can be useful if dropped calls (cutoffs) are reported by users of the ISDN-PRI trunks.
The meanings of Aux Data values are shown below; ignore any others.
•
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.
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.
Table 89: Aux Data Values
Aux Data Cause
0 A idle trunk received a restart.
10 A call in a stable, talking state was cleared unexpectedly by the far-end with an
ISDN RESTART message. This state is called the “active” state.

A call that has not reached the active state, but has at least reached a ringing
state, was cleared unexpectedly by the far-end with an ISDN RESTART
message.

A call that was in the process of clearing anyway has been cleared by the far-
end with an ISDN RESTART message. If this condition occurs frequently, it
may mean that the far-end is attempting to clear trunks that it thinks are in a
“hung” state. The RESTART message brings the trunk to an idle condition.
