TSI Looparound Test (#1108)
This test is non-destructive. During this test, the MMI's Time Slot Interchanger
(TSI) is listens to a TDM timeslot. A digital count tone loops back in the TSI and
onto another TDM timeslot without passing through any resource hardware. A
tone detector port verifies the looped data. If the digital count is correct, then the
test passes. The test is done for both TDM buses. Failures indicate that the TSI is
unreliable.

Error Test
Code Result
ABORT Internal system error. This is an abnormal abort.
1002 ABORT The system could not allocate time slots for the test. Either the traffic load on the
system is very high or time slots is out-of-service due to TDM-BUS errors. Refer
to
1003 ABORT The system could not allocate a tone detector for the test. The system may be
oversized for the number of Tone Detectors present, or some Tone Detectors
may be out-of-service.
2000 ABORT Response to the test was not received from the Tone Detector circuit pack within
the allowable time period.
2012 ABORT Internal system error. This is an abnormal abort.
2100 ABORT Could not allocate the necessary resources to run this test. This is an abnormal
abort.
FAIL The TSI was found to be transmitting in error, causing noisy and unreliable
connections.
PASS The TSI is correctly using its allocated time slots.

Description/Recommendation
1. Retry the command at 1-minute intervals a maximum of 5 times.
''TDM-BUS (TDM Bus)''
1. If the system has no TDM-BUS errors and is not handling heavy traffic,
repeat the test at 1-minute intervals a maximum of 5 times.
1. Resolve any ''TTR-LEV (TTR Level)''
2. Resolve any ''TONE-PT (Tone Generator)''
3. If neither condition exists, retry the test at 1-minute intervals a maximum of 5
times.
1. If this result occurs repeatedly, attempt to reset the circuit pack (if the other
ports are not in use). Reset the circuit pack by issuing the busyout board
PCSSpp and the reset board PCSSpp commands followed by the release
board PCSS command.
2. If this result occurs again, replace the circuit pack.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1. Replace the circuit pack.
