Notes:
1. At the administration terminal, busyout the affected port, and run a Long
Test Sequence. Observe the test results. If any tests fail, refer to the
description of the tests and the associated error codes. Release the port.
If users continue to report troubles, check for other errors and make test
calls to determine whether the problem should be escalated or referred to
the CO.
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.
Check for other errors.
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.
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.
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.
See Notes 1 and 2 at end of
table.
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 3 at end of table.
