BRI Layer 3 Query Test (#629)
This test is used to check the ap plication layer communi cations between the
switch and the endp oint or adjunct.
For BRI endpoints, an applicatio n message containing the ap propriate endp oint
service state is sent by the switc h to the endpoint. The endpoint resp onds with an
acknowledgment to the ap plication messag e.
For ASAI and Lucent adjuncts, this test is not exec uted from the administration
terminal. Rather, a query message is automatic ally sent by the switch ever y two
minutes. Failure of the switch to receive a response to a q uery from the adjunct is
logged in the Hard ware 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 c ontinues
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.
