b. Error Type 2: violations of the ISDN-BRI signaling protocol; timers associated with certain
layer-3 messages have expired before a required response was received. In the following
table, the aux data field indicates what timer has just expired.
The switch sent a message to the endpoint that did not respond in the allotted time. This
can happen occasionally due to failure of the point-to-point signaling link or because of a
problem in the BRI endpoint or ASAI adjunct or Avaya adjunct. Execute test station
extension sh and pay particular attention to the results of the BRI Layer 3 Query test
(#629). If this test fails, follow the repair procedure for Test #629.
c. Error Type 130: the circuit pack has been removed or has been insane for more than 11
minutes. To clear the error, replace or reinsert the circuit pack.
d. Error Type 257: the endpoint does not respond to the service state query message sent to
the adjunct or the endpoint. This error causes an alarm to be raised. The alarm is retired
when the switch receives a response to the service state query to the endpoint or the
adjunct.
For BRI endpoints, the Aux Data field for this error contains “0.” When it occurs, execute
test station extension sh and pay particular attention to the results of the BRI
Layer 3 Query test (#629). If this test fails, follow the repair procedure for Test #629.
