Analog Port Digital Loop-Around Test (#13)
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.
