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 Lucent 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 documentation to determine if the Layer 2 XID and
XID-RESPONSE messages are supported. If the documentation reflects
no support for these messages, change XID Testing? field to ‘‘no’’ using
the change station extension command.
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.

Management and Maintenance Procedures.
