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.
