Avaya 03-300430 User Manual

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.

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.

ABRT

The endpoint’s MIMs Supported? field is administered to “no.”

1. Use change station extension to change the parameter only if 

the endpoint documentation reflects support for ISDN-BRI 
Management and Maintenance Procedures.
