b. Software audit error and does not indic ate a hardware malfunction. Run
the Short Test Sequence and investigate associated errors.
c. The far-end switch changed its ISDN service state to either
out-of-service
or
maintenance
. This may be a temporary cond ition due to testing of that
trunk by the far-end, or a hardware p roblem with the trunk. Outgoing calls
will not be allowed over the trunk. To investigate the status of the trunk,
issue the status trunk group#/member# c ommand.
d. This Error Type indicates that the circuit pack ha s been removed or has
been insane for more than 11 minutes. To clear the error, reinsert or
replace the circuit pack.
e. These Error Types indicate a d isagreement between this switch and the
switch at the other end of the trunk c onnection with regard to the ISDN
service state of the DS1 ISDN Trunk. This switch will automatically try to
recover by performing a service state audit. You can use the status trunk
group#/member# c ommand to determine the state of the trunk.
When running the Short Test Sequence, pay close attention to the results
of the Service State Audit Test (#256).
f. This trunk is not recognized by the far-end switch. Investigate the trunk
administration for both switc hes and make changes as nec essary.
g. This error indicates a failure of the DS1/UDS1 Interface circu it pack. When
running the Short Test Sequence, the results of the Signaling Link State
Check Test (#255) are important.
h. Service State Audit attempt failed (see Test #256). The trunks will not be
usable for any outgoing c alls (although incoming calls will be accep ted)
until the test passes and the trunk sta te is changed to in-servic e (use
status trunk group#/member# to investig ate trunk status).
i. 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 c alls (cutoffs) are reported b y users of the ISDN-PRI trunks.
The meanings of Aux Data values are shown below; ig nore any others.
Aux
Data Cause
0 A idle trunk receved a restart.
10 A call in a stable, talking state was cleared unexpected ly by the far-end
with an ISDN RESTART message. This state is called the "active" state.
