Digital Port 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 digital 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 is the same
test as Conference test (#6).
1004 ABRT The port has been seized by a valid ISDN-PRI test call. Use list
isdn-testcall to determine which call is using the port (from the M/
T Port column). Wait for the test call to complete as indicated in the Start
Time and Duration fields of the above display, or abort the test call with
clear isdn-testcall grp#/mem#, where grp#/mem# is determined
screen the B-channel field list isdn-testcall.
1. Retry the command at 1-minute intervals up to 5 times.
2. If the test continues to abort and the port is idle, escalate the problem.
2000 ABRT Response to the test request was not received within the allowable time
period.
2100 ABRT System resources required to run this test are not available.
1. Retry the command at 1-minute intervals up to 5 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 idle (amber LED is off), try to reset
the circuit pack. 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 using other port tests and by examining
station, trunk, or external wiring.
