System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order they are presented in the table below when
inspecting errors in the system. By clearing error codes associated with the
NPE
Crosstalk Test,
for example, you may also clear errors generated from other tests
in the testing sequence.
3329 57408 Trunk error. No Tip ground detected on outgoing call. This error occurs
when an attempt is made to seize a ground-start CO trunk for an outgoing
call and Tip ground is not detected or the caller hangs up before Tip ground
is detected.
1. Busyout the affected port, and run a long test. Observe the test results.
If any tests fail, refer to the description of the tests and the associated
error codes. Release the port.
2. If users continue to report troubles, check for other errors and make test
calls to determine whether the problem should be referred to the CO.
Busyout the affected port, and run a long test. If Dial Tone Test #0
passes, ignore this error. Release the port.
3585 57424 No loop current on outgoing call. This error occurs on attempt to seize a
loop or ground-start trunk for an outgoing call. An error occurs if loop
current is not detected or the caller hangs up before it is detected. Busyout
the affected port, and run a long test. If CO Demand Diagnostic Test #3
passes and this error keeps occurring, refer problems to CO. Release the
port.
