Note: This Test will abort with Error Code

Description and Recommendation
CO not releasing after call is dropped from PBX . After several
occurrences, an off-board warning alarm is generated. Refer
problem to CO .
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.
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.
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.
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 Dial
Tone Test #0 passes, ignore this error. Release the port.
Always investigate tests in the order they are presented in the table below. 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
