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:
