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.

Data Description and System Action System Technician Action
769 57392 CO not releasing after call is dropped from PBX
end (TN747B), or the loop is not open after a
disconnect (TN765). After several occurrences, an
off-board (TN747B) or on-board (TN465) warning
alarm is generated.
Refer problem to CO.
2561 57345 Single polarity ringing current. This error results
from abnormal ringing current, but does not
prevent the incoming call from being accepted.
One cause could be that the reverse current
detector associated with the port is failing. (Will not
be detected by any tests.) The other cause could
be that normal current is not detected. In this case,
neither incoming nor outgoing calls can be
completed, and the dial tone test also fails.
Check for other errors.
2817 57393 CO released the trunk at least four minutes after the
PBX dropped the call. This error code is log only
and causes no other testing to occur. No alarm is
generated.
Check for other errors.
3073 57376 No loop current on incoming call. The incoming
destination has already answered and no loop
current has been detected. If this is a hard fault, the
dial tone test and all outgoing calls should also fail.
Check for other errors.
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.
See Note at end of table.
