For example, you may also clear errors generated from other tests in the testing
sequence.
Notes:
a. A demand test of Diag nostic Test (#3) always returns a PASS indication for
CO-TRK/CO-BD [TN747B] version 8 or greater. However, any errors
produced as a result of this test are logged and p roduce no alarms.
If errors logged b y Test #3 are the only complaints against this trunk, then
the system technician per son should check if MFT/Range Extenders are
being used. If extend ers are present, then there is a good c hance that
there is excessive loop current, whic h causes Test #3 to log errors.
However, all else being normal, these e rrors should not affect the
customer.
b. Refer to TIE-TRK (Tie Trunk) Maintenance documentation for a d escription
of this test.
c. ATMS test are not part of either sequence. They are run either on d emand
with the test analog-testcall command or via the ATMS schedule.
