Result Description/ Recommendation
any code
other than
1005 ABORT Internal system error
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.
none FAIL Communication through the Control Channel is not working. The problem is
not necessarily the TDM Bus itself.

pack. Refer to TONE-BD (Tone-Clock Circuit Pack) Maintenance
documentation.
