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.
1003 ABORT The system could not allocate a tone detector for the test. The system is
oversized for the number of tone detectors present, or some tone detectors
are out-of-service.
1. Resolve any ‘‘TTR-LEV (TTR Level)’’
errors in the Error Log.
2. Resolve any ‘‘TONE-PT (Tone Generator)’’
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 MMI-BD 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 PCSS, reset board PCSS, followed by the release board PCSS
commands.
2. If this result occurs again, replace the circuit pack.
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.
1. Retry the command at 1-minute intervals a maximum of 5 times.
FAIL The TSI was found to be transmitting in error. This causes noisy and
unreliable connections.
1. Replace the circuit pack.
PASS The TSI is correctly using its allocated time slots.
