b. Error Type 2:  ISDN-BRI signaling protocol violation.  Timers associated with layer-3 

messages expired before a required response was received.  In the following table, the aux 
data column indicates which timer has just expired.

The switch sent a message to an endpoint that did not respond in the allotted time.  This 
may be due to failure of the point-to-point signaling link or because of a problem in the ASAI 
adjunct.  To repair:

●

Execute test station extension and perform the associated repair procedures for 

those tests.

c. Error Type 257: An endpoint is not responding to the service state query message sent to 

the adjunct or to 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 to the 
adjunct.

When this error occurs for an ASAI adjunct, the Aux Data field indicates the state of the 
ASAI link and whether an invalid response or no response was received to the query from 
the switch, as shown in the following table:
