First, the primary information (voice) c hannel loopback test send s a digital coun t
from the Tone-Clock circuit pack on the pr imary information channel time slot and
receives the same digital c ount with a general purpose tone d etector.
While the primary information channel is still loop ed around, the Control Channel
Loop Around Test sends four different transparent p atterns to the on-board
microprocessor, receives them back, and co mpares them.
The Loop Around Test for the secondary information (d ata) channel is the same
as the primary information c hannel loop around test and is p erformed only if a
DTDM is administered.
Next, a Conference Test checks the primary information c hannel. 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 sequenc e 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 servic e state of the port. If the por t 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 b usied out.
2. If the port statu s is idle, then retry the comma nd 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.
