This test is a modification of the Voice and Control Channel Local Loop test used by Digital 
Station (DIG-LINE) maintenance. This test does not perform the control channel and secondary 
information channel loop around tests as described for DIG-LINE, as these data paths do not 
exist for the Maintenance/Test analog port. To test the primary information channel, this test:

1. Loops back the data channel onto the TDM bus

2. Sends a digital count from the Tone-Clock circuit pack and receives the same digital count 

with a general-purpose tone detector

3. Runs a conference test for the primary information channel. This is the same test as 

Conference test (#6).

Only one value (Pass, Fail, or Abort) is generated as a result of the two tests. If it fails or aborts, 
the sequence is stopped.

Any

FAIL

The NPE of the tested port was found to be transmitting in error. This will 
cause noisy and unreliable connections.

1. If the remaining ports are currently idle (amber LED is off), try to reset 

the circuit pack using busyout board location, reset board 
location, and release board location. Repeat the test.

2. If the test fails again, replace circuit pack.

PASS

The port is correctly using its allocated time slots. User-reported troubles on 

this port should be investigated by examining station, trunk, or external 

wiring.
