Table 160. CO Trunk Errors with NO Tests — Continued
Error Aux
Type Data
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.) Another 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. The last cause could be that certain types
of noise are present on the CO line during the
silent period of ringing.
2817 57360 Ground but no ringing. This error occurs on an
incoming call on a ground-start trunk. If ringing
is not detected within 5 seconds of the Tip being
grounded, the call is still accepted. If the CO is
of the No. 5ESS. switch type, ringing delays of
more than 5 seconds during heavy traffic are
fairly common.
2817 57393 On the TN465, the loop is opening too slowly
after a disconnect. This error indicates an
on-board problem, although the trunk may be
functional. On the TN2138, CO released the
trunk at least 4 minutes after the PBX dropped
the call. This error code is log-only and causes
no other testing to occur. No alarm is
generated.
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.
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.
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.
