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.
1. Display the hardware error and alarm log for the
Tone-Clock circuit pack. Refer to TONE-BD (Tone-Clock
Circuit Pack) Maintenance documentation.
2. Resolve the errors for the Tone-Clock circuit pack.
3. Display the hardware error and alarm log for the Network
Control circuit pack. Refer to DATA-BD (Network Control
Circuit Pack) Maintenance documentation.
4. If this error is on the EPN, display the hardware error and
alarm log for the Expansion Interface. Refer to EXP-INTF
(Expansion Interface Circuit Pack) Maintenance
documentation and resolve its errors.
5. Execute the test tdm P command again.
6. If the test still fails, refer to the ‘‘TDM Bus Fault Detection
