For example, you may also clear errors generated from other tests in the testing
sequence.
Notes:
a. A demand test of Diagnostic 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 produce no alarms.
If errors logged by Test #3 are the only complaints against this trunk, then
the system technician person 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 causes Test #3 to log errors.
However, all else being normal, these errors should not affect the
customer.
b. Refer to TIE-TRK (Tie Trunk) Maintenance documentation for a description
of this test.
c. ATMS test are not part of either sequence. They are run either on demand
with the
test analog-testcall
command or via the ATMS schedule.
Dial Tone Test (#0)
This test attempts to seize a port and checks for the return of a dial tone.
