Maintenance Object Repair Procedure
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).
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.
