CO-TRK (Analog CO Trunk)
Issue 1 June 2005 843
Note:
Note: A Demand Diagnostic test (#3) will always return a PASS indication for CO-TRK/
CO-BD [TN747B] version 8 or greater. 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 the
system technician should 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:
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.
