In the Log column, put a checkmark in the box if you want the system to
record trunk group grade of service exceptions. If you do not want to record
exceptions, leave the box unchecked.
4 In the Level column, set the alert level for the event by clicking on the arrow in
the Alert level pull-down list and selecting one of the options.
5 In the Model column, select the model to use in calculating trunk group grade
of service. The Retrial calculation is an approximation of the standard Retrial
calculation. It is basically the average of Erlang B and Erlang C.
Choose one of the following options:
• Erlang B
• Erlang C
• Retrial
6 In the Service Objective column, type a number between .001 and .700 that
represents the percent of calls that will be blocked from accessing that trunk
group based on the current call activity. Trunk group grade of service events
are generated when the computed service objective exceeds the value in this
field.
