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 loo ps back in the TSI and onto another TDM timeslot

without passing through any resourc e hardware. A tone detector p ort verifies the

looped data. If the d igital count is c orrect, 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 errors.
2. Resolve any TONE-PT errors.
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 UUCSS, followed by the release board UUCSS
commands.
2. If this result occurs again, replace the circuit p ack.
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 c ircuit pac k.
PASS The TSI is correctly using its alloc ated time slots.
