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 AT&T 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.
