CO-TRK (CO Trunk)
Notes for Table
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, 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.
