c. Aux data 57376 - No loop current on incoming call
Aux data 57424 - No loop current on outgoing call
These errors cause the Dial Tone Test (#0) to run and are only considered
a problem if the Dial Tone Test fails (in which case Error Type 1537 also
shows up). In this case, the trunk may be put in "Ready-for-Service" state
(shown as "disconnected" by status command), which allows only
incoming calls. Run the Dial Tone Test (#0) and follow its outlined
procedures.
d. Single polarity ringing current - This error results from abnormal ringing
current, but does not prevent the incoming call from being accepted. This
error code is only logged as an informational event and causes no other
testing to occur.
e. Late CO Trunk release - This error indicates that the CO releases the trunk
at least four minutes after the PBX dropped the call. This error code is only
logged as an informational event and causes no other testing to occur.

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.
