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.
