Maintenance-Object Repair Procedures
555-233-143
8-172 Issue 1 May 2002
b. Error Type 129: the far-end switch changed its ISDN service state to either
out-of-service or maintenance. This may be a temporary condition
because the far end is testing that trunk or a hardware problem with the
trunk. Outgoing calls may not be allowed over that trunk.
1. Investigate the trunk’s 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 pack to clear the error.
d. Error Type 257: SETUP received for a B channel that is in an invalid
service state. Service states may be incompatible at the two ends 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 received with cause value
82 (nonexistent channel). The B channel may not be administered at the
far end. The trunk has been placed in the OOS/FE state.
f. Error Type 769: inconsistent SERVice or SERVice ACKnowledge
message. Possible causes:
■ SERVice or SERVice ACKnowledge message received containing a
change status that is more available than the previously-transmitted
SERVice message.
■ Unsolicited SERVice ACKnowledge message received containing a
change status that does not match the current B-channel state.
ISDN-PRI service-state negotiation rules have been violated and may
indicate that a pending service-state audit is failing. The system:
■ cancels the maintenance timer
■ increments the Service State Audit counter
■ 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 possible) containing a
change status of OOS for the B channel
■ returns the trunk to service when the ATM trunk circuit pack reports
the failure cleared
h. Error Type 3073: Service State Audit attempt failed. See ‘‘Service State
Audit 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’s status (status trunk grp#/mbr#).
