CO-TRK (Analog CO Trunk)
Issue 1 May 2002
8-461555-233-143
2000 ABORT Response to the test was not received within the allowable time period.
1. Retry the command at 1-minute intervals up to 5 times.
FAIL Trunk was seized, but dial tone could not be detected.
1. Test every administered outgoing port on the board. Failure of 1 port
indicates a problem toward the CO.
2. If every port fails, 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 every port on a circuit pack, a -5 Volt power
problem is indicated. To investigate problems with a power unit, see
‘‘CARR-POW (Carrier Power Supply)’’.
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 the one under
test. Repeat test on both trunks, and determine whether 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.
1009 PASS Detected tone was not pure dial tone. No action required.
