the testing sequence.

none FAIL This failure indicates that communication on the Non-Control Channel is not
reliable.
1. Execute the command again.
2. If the problem persists, test the Tone-Clock circuit pack and Tone
Detector circuit pack to make sure they are healthy. Refer to TONE-BD
(Tone-Clock Circuit Pack), TONE-PT (Tone Generator), GPTD-PT
(General Purpose Tone Detector Port), and DTMR-PT (Dual Tone
Multifrequency Port).
3. Execute the command again.
4. If the problems persists, refer to the ‘‘TDM Bus Fault Detection and
