Investigate tests in the order presented. By clearing errors associated with the first test, errors generated from other tests may also be cleared. Click the link to see the full description of the test, error codes, and recommended actions.
Note:
The CO Port Diagnostic Test (#3) will always return a PASS indication for CO-TRK/CO-BD. However, any errors produced as a result of this test will be logged and produce no alarms. If errors logged by Test #3 are the only complaints against this trunk, then check if MFT/Range Extenders are being used. If extenders are present, then there is a good chance that there is excessive loop current, which will cause Test #3 to log errors. However, all else being normal, these errors should not affect the customer.
Note:
The ATMS tests are not part of either test sequence. They are run either on demand with test analog-testcall or by the ATMS schedule.
