3-399CO-TRK (CO Trunk)
3
FAIL Trunk was seized, but dial tone could not be detected.
1. Test all administered outgoing ports on the board. Failure of 1
indicates a problem toward the CO.
2. If all fail, see note below.
3. Check for errors on the TONE-BD or TONE-PT. Clear any errors found,
and repeat the test.
4. If the error has still not cleared, refer the problem to the CO.
5. If no service problems exist on the port, continue to use the port until
the circuit pack can be replaced (as a last resort). Perform a trunk test
call to see if the trunk is operable.
NOTE:
If the dial tone test fails for all ports on a circuit pack, a -5 volt power
problem is indicated.
2002 FAIL Seizure portion of test failed due to hardware problem. Fault is usually
caused by a disconnected trunk.
1. If the CO Demand Diagnostic Test (#3) also failed, display the
Hardware Error Log. If the CO Demand Diagnostic Test failed because
it could not detect ground (indicated by Error Type 1281 in the
Hardware Error Log) AND Error Type 3329 or 3585 appears in the
Hardware Error Log (with the same last occurred time as Error Type
1281 and 1537), replace the circuit pack.
2. Check trunk wiring to ensure good connection; repeat test if wiring
correction made.
3. Locate another identical CO trunk and swap its wiring with one under
test. Repeat test on both trunks and determine if problem follows trunk
or remains at original port. If problem follows trunk, refer problem to
CO. If problem remains at port, replace circuit pack and repeat test.
4. If replacing circuit pack does not clear failure, escalate the problem.
1009 PASS Detected tone was not pure dial tone. No action is required.
PASS Trunk was seized, and dial tone was detected. User-reported troubles on
this port should be investigated by using other port tests and by examining
trunk or external wiring.
