Order of Investigation
NPE Crosstalk Test (#6)
Dial Tone Test (#0)
CO Demand Diagnostic Test (#3) (a)
Loop Around and Conference Test (#33)
Audit Update Test (#36)
Analog Transmission Test (#844-848) (b)
1. D = Destructive; ND = Nondestructive
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, the
system technician should check if MFT/Range Extenders are being used. If
extenders are present, there may be 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 with ATMS schedule.
Dial Tone Test (#0)
This test attempts to seize a port and checks for the return of a dial tone.
