ABORT Internal system error.
1. Retry the command at one-minute intervals for a maximum of three 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 port-network command to verify which b us 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
and for the Tone Detector circuit pack in the port network where the faulted
TDM Bus resides. Refer to Maintenance documentation for TONE-BD
(Tone-Clock Circuit Pack), TONE-PT (Tone Generator), GPTD-PT (General
Purpose Tone Detector Port), and DTMR-PT (Dual Tone Multi-Frequency
Port).
2. Resolve the errors and alarms for the Tone-Clo ck and Tone Detector circuit
packs.
3. If the faulted TDM Bus is in the PPN, display the hardware error and alar m
log and look for SW-CTL errors and alarms.
4. If the faulted TDM Bus is on the EPN, display the hardware error and alarm
log and look for errors and alarms for the active Expansion Interface circuit
pack. 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 and Isolation
Procedure’’ described earlier.
PASS Communication through the control channel bus is operational.
