QSIG Networks
If a non-Supplementary Services B (SSB) trunk preference is selected for rerouting a SSB call,
QSIG feature transparency is lost. If LAR for a QSIG call is done through either the same or
another SS B trunk group, feature transparency is not lost.
•
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, see Reports for
Avaya Communication Manager.

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. Avaya recommends that you seek technical
assistance from Avaya 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
Location Parameters screen. An Avaya representative must enable these fields for you.
The 2 Party Loss Plan page of the Location Parameters 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
on the Station and Trunk Group screens. This allows you to use different loss plans for different types of
phones or different trunk groups.
