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.

Result Description/Recommendation
ABORT Internal system error. This is an abnormal abort.
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. Either the
traffic load on the system is very high or time slots is
out-of-service due to TDM-BUS errors. Refer to “TDM-BUS” to
diagnose any active TDM Bus errors.
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.
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.
1. Resolve any “TTR-LEV” errors in the Error Log.
2. Resolve any “TONE-PT” errors in the Error Log.
3. If neither condition exists, retry the test at 1-minute intervals
a maximum of 5 times.
2000 ABORT Response to the test was not received from the Tone Detector
circuit pack within the allowable time period.
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.
2012 ABORT Internal system error. This is an abnormal abort.
