Investigate tests in the order presented. By clearing error codes associated with the Voice and 
Control Channel Local Loop-Around test, you may also clear errors generated from other tests 
in the sequence.

Note:

On the G700/ G350, this test aborts with Error Code 1412.

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 Communication Manager 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.

1. First the primary information (voice information channel 1 or l1) channel loop-back test is 

run. The test is performed by sending a digital count from the Tone-Clock circuit on the 
primary information channel time slot and receiving the same digital count with a general 
purpose tone detector.
