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 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.
