Descriptions and Error Codes
Always investigate tests in the order presented in the table below. By clearing
error codes associated with the Voice and Control Channel Local Loop-around
test, for example, you may also clear errors generated from other tests in the
testing sequence.

Digital Terminal Remote Loop-around Test
(#1201)
This test checks the connection between the media server and the digital terminal
and the ability of the terminal and the associated port to send and receive data.
This test is based on procedure 622 to isolate digital terminal problems.
A request is presented to the terminal to go into loop-back mode. Data is sent to
the terminal and when received back, checked for consistency. This test is run as
a part of the test long procedure. It is not included in any error recovery strategy
and generates no error log entries or alarms. To begin the test, Maintenance will
ask Avaya MultiVantage ™ software to make the associated endpoint and port
Maintenance Busy. This test succeeds if the endpoint is "idle". If the reserve
request fails then the test aborts. If the request succeeds then the media server
sends a message to loop around both information channels for the digital terminal.
