First, the primary information (voice) channel loopback test sends a digital count
from the Tone-Clock circuit pack on the primary information channel time slot and
receives the same digital count with a general purpose tone detector.
While the primary information channel is still looped around, the Control Channel
Loop Around Test sends four different transparent patterns to the on-board
microprocessor, receives them back, and compares them.
The Loop Around Test for the secondary information (data) channel is the same
as the primary information channel loop around test and is performed only if a
DTDM is administered.
Next, a Conference Test checks the primary information channel. This test is the
same as Conference Test #6.
The four tests generate only one result: Pass, Fail, or Abort. If any test fails or
aborts, the test sequence stops.

Result Description/ Recommendation
ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
1000 ABORT System resources required to run this test are not available. The port may
be busy with a valid call.
1. Use display port UUCSSpp to determine the station extension or
attendant number of the port. Use status station or status attendant
to determine the service state of the port. If the port is in use, wait until
it is idle before retesting. Attendants are always in use (off-hook) if the
handset is plugged in and the port is not busied out.
2. If the port status is idle, then retry the command at 1-minute intervals a
maximum of 5 times.
1001 ABORT System resources required to run this test are not available.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1002 ABORT The system could not allocate time slots for the test. The system is under
heavy traffic conditions or it has time slots out-of-service due to TDM-BUS
errors.
1. If system has no TDM-BUS errors and is not handling heavy traffic,
repeat test at 1-minute intervals a maximum of 5 times.
