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.
The primary information channel is tested by first looping back the data channel
onto the TDM Bus, and then sending a digital count from the Tone-Clock circuit
pack and receiving the same digital count with a general purpose tone detector.
A conference test is done next for the primary information channel. This test is the
same as Conference Test (#6).
Only one value (Pass, Fail, or Abort) is generated as a result of the two tests. If
either fails or aborts, the sequence is stopped
2000 ABORT Response to the test request was not received within the allowable time
period.
1. Retry the command at 1 minute intervals a maximum of 3 times.
2. If the test continues to abort, escalate the problem.
2100 ABORT System resources required to run this test are not available.
1. Retry the command at 1 minute intervals a maximum of 3 times.
2. If the test continues to abort, escalate the problem.
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 not in use (yellow LED is off), try to
reset the circuit pack via the busyout board PCSS, reset board
PCSS, release board PCSS command sequence. Then 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.
