Maintenance-Object Repair Procedures
h. An unexpected SERVICE or SERVICE ACK was received. Possibilities
include:
i. This error indicates a failure of the DS1/UDS1 Interface circuit pack. When
running the short test sequence, the results of the Signaling Link State
Check test (#255) are important.
j. Service State Audit attempt failed (see Test #256). The trunks will not be
usable for any outgoing calls (although incoming calls will be accepted)
until the test passes and the trunk state is changed to in service (use
status trunk group#/member# to investigate trunk status).
k. 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.

Cause
A idle trunk received a restart.
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 has not yet 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.
