■ Ringback Queuing
When a call originates and queues at the trunk group queue, the call can be
placed in queue multiple times if LAR is active. The call originator can be
called back each time the call is continued automatically.
■ Satellite Hop Limit
Satellite Hop Limit always takes precedence over LAR. When the
maximum hop limit is reached for a route preference, the last call routing
attempt is denied and the call is rejected with a cause value of #28 —
invalid number format. This value does not activate LAR.
■ System Measurements
System resource use during LAR attempts are included in existing system
measurements and performance reports. For more information about LAR
system measurements, refer to DEFINITY ECS Reports.

Loss Plans
Loss plans determine the amount of loss (quieter) or gain (louder) applied on
calls. Usually, your system uses a pre-defined loss plan that is based on the
administered country code. In some circumstances, you may be able to change the
loss plan used by your system on a per trunk or per phone basis.
!
CAUTION:
The values in the loss plan can significantly affect the quality of service that
your users experience. Therefore, in order to change the loss plan you must
thoroughly understand loss plans and your particular configuration. We
recommend that you seek technical assistance from Lucent before making
any modifications to the loss plan.
In order to be able to modify your loss plan, the Digital Loss Plan Modification
field must be set to
y on the System Parameters Customer-Options screen, and the
Customize field must also be
y on the System Parameters Country-Options screen.
A Lucent technologies representative must enable these fields for you.
The 2 Party Loss Plan page of the System Parameters Country-Options
screen
allows you to set the gain or loss levels (in dB) between two parties on a call. Each
row on this screen is considered a different loss group. You can assign a loss group
to a particular phone or trunk by administering a value for the Loss Group fields
