Data Description and Recommendation
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 ac cepted. One cause could
be that the reverse cu rrent detector assoc iated with the port is fail ing. (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 c alls 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 d estination 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 c all. 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 d etected. Busyout the affected
port, and run a Long test. If Dial Tone Test #0 passes, ignore this error.
Release the port.
