●

Outgoing call renegotiated by the far end to another B channel in the absence of SETUP 
message glare

●

Near end attempted a call on a B channel that the far end has marked OOS

When running the short test sequence, pay close attention to the results of the Call State 
Audit test (#257).

c. 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#/mem#).

d. 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.

e. 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.

f. 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.

g. 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).

h. Error Type 1793: TN230x circuit pack 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
