This test tests the integrity of the Control Channel bus. It ensures that
communication through the TDM Bus is operational.

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.

1. Retry the command at 1-minute intervals a maximum of 5 times.
1005 ABORT Since this test is valid only on the control channel bus, it aborts execution
when run on the non-control channel bus. This is a valid response. Use the
status system command to verify which bus is the control channel bus.
