1. Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer to the appropriate test 
description and follow the recommended procedures.
2. This alarm will only be raised when the System-Parameter Country form has the Base Tone Generator field set 
to 4 (Italy). This alarm will be a MINOR alarm unless 75% or more trunks in this trunk group are out of service, 
then the alarm will be upgraded to a MAJOR alarm.
