b. Error Type 129: the far-end switch changed its ISDN service state to either
out-of-service or maintenance. This may b e a temporary cond ition
because the far-end is testing that trunk or a hardware probl em with the
trunk. Outgoing calls may not b e allowed over that trunk.
1. Investigate the trunk status (status trunk
grp#/mbr#
).
c. Error Type 130: the circuit pack has been removed or has been insane for
more than 11 minutes.
1. Reinsert or replace the circuit pac k to clear the error.
d. Error Type 257: SETUP received for a B-channel that is in an inva lid
service state. Service states may be inc ompatible at the two end s of the
trunk. A normal call was received while the B-channel was MTC/FE,
MTC/NE, OOS/FE, or OOS/NE or a test call was received while the
B-channel was OOS/FE or OOS/NE.
e. Error Type 513: RELease COMplete message rec eived with cause value
82 (nonexistent channel). The B-channel may not b e administered at the
far end. The trunk has been plac ed in the OOS/FE state.
f. Error Type 769: inconsistent SERVice or SERVice ACKnowledge
message. Possible causes:
■SERVice or SE RVice ACKnowledge message rece ived containing a
change status that is more available than the p reviously-transmitted
SERVice message.
■Unsolicited SERV ice ACKnowledge message received containing a
change status that does not ma tch the current B-channel state .
ISDN-PRI service-state negotiation rules have been violated and may
indicate that a pend ing service-state aud it is failing. The system
■cancels the maintenance timer
■increments the Service State Audit cou nter
■attempts a Service State Audit
When running the Short Test Sequence, pay close attention to the results
of the Service State Audit Test (#256).
g. Error Type 1793: TN230x circuit pack has failed. The maintenance system
■places the trunk in the OOS/NE state
■sends a SERvice message to the far-end (if p ossible) containing a
change status of OOS for the B-channel
■returns the trunk to service when the ATM trunk circuit pack rep orts
the failure cleared
h. Error Type 3073: Service State Audit attempt failed (see Test #256). Calls
can be received but not placed until the test passes and the trunk state
returns to In-Service.
1. Check the trunk status (status trunk
grp#/mbr#
).
