Maintenance-Object Repair Procedures
1. First the primary information (voice information channel 1 or l1) channel
loop-back test is run. The test is performed by sending a digital count from
the Tone-Clock circuit on the primary information channel time slot and
receiving the same digital count with a general purpose tone detector.
2. If the primary information channel test is successful, the loop-around test
for the secondary information (data, Information Channel 2 or I2) channel is
then performed. This is the same test as the primary information channel's
loop around test and is performed only if a DTDM is administered. This is
also the case for a linked DA.
Only one value (Pass, Fail, or Abort) is generated as a result of the two tests run.
If any test fails aborts, the sequence is stopped. Upon completion of this test, the
associated endpoint and port are moved back into the previous service state.
