Idle Time Slot Test on TDM Bus A or B (#294)
The Idle Time Slot Test detects noisy time slots on the bus and takes them
out-of-service. The Tone Detector circuit pack is told to listen to idle time slots and
if it detects any noise on a time slot, it returns a failure. At the end of the test, any
out-of-service time slots are retested to see if they are still noisy and restored to
service if they are idle. After all the time slots have been tested, maintenance
counts the number of bad time slots and reports the number to the technician in
the error code field. No more than 220 time slots are taken out-of-service on one
bus, and no more than 300 are taken out-of-service on both buses at one time.

Error
Code Test
Result Description/ Recommendation
none ABORT Could not allocate the necessary system resources to run this test. For
example, maintenance could be running on the Tone Detector circuit pack
and it is using the CPTRs.
1115 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
number FAIL The error code indicates the number of bad time slots that were detected.
The cause of this failure is most likely due to a bad port circuit pack and not
the TDM Bus itself.
1. Execute the command again.
2. If the error persists, check the Error and Alarm Logs for alarms on port
circuit packs from the NPE Crosstalk Test.
3. Refer to the appropriate circuit pack’s documentation to clear the circuit
pack’s problem.
4. Test the TDM Bus again. If the error continues, refer to the ‘‘TDM Bus
Fault Detection and Isolation Procedure’’ described earlier.
PASS The success of this test indicates all the idle time slots that are supposed to
be idle are indeed idle. There is no noise on any of the idle time slots.
