BRI-SET, Various Adjuncts
Issue 1 June 2005 727
BRI Layer 3 Query Test (#629)
This test is used to check the application layer communications between the switch and the
endpoint or adjunct.
For BRI endpoints, an application message containing the appropriate endpoint service state is
sent by the switch to the endpoint. The endpoint responds with an acknowledgment to the
application message.
For ASAI and Avaya adjuncts, this test is not executed from the administration terminal. Rather,
a query message is automatically sent by the switch every two minutes. Failure of the switch to
receive a response to a query from the adjunct is logged in the Hardware Error Log.
2000 FAIL The XID-RESPONSE message was not received from the endpoint.
1. Consult the endpoint’s documentation to determine whether layer-2
XID and XID-RESPONSE messages are supported. If the
documentation reflects no support for these messages, use change
station extension and change the XID Testing field to n.
2. If the endpoint supports these layer-2 messages and the test continues
to fail, assume the endpoint is defective and replace it.
3. If the test continues to fail, escalate the problem.
PASS The switch can successfully pass messages over the D channel to the BRI
endpoint.
