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.
2. At the administration terminal, busyout the affected port, and run a Long
Test Sequence. If Dial Tone Test #0 passes, ignore this error. Release the
port.
3. At the administration terminal, busyout the affected port, and run a Long
Test Sequence. If CO Demand Diagnostic Test #3 passes and this error
keeps occurring, refer problems to CO. Release the port.
4. If the error count associated with this error type is very high (that is, 255)
and all tests pass, then either the reverse current detector is defective or
the CO line is noisy. If the CO line is suspected, Tip and Ring observations
should be made. If the line is determined to be noisy, the problem should
be referred to the CO. If the reverse current detector is defective, ignore
this error.
3329 57408 Trunk error. No Tip ground detected on
outgoing call. This error occurs when an

CO trunk for an outgoing call and Tip
ground is not detected or the caller

See Notes 1 and 2 at end of

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
