Outgoing Display
— Typing y in this field allows display phones to show the name and group
number of the trunk group used for an outgoing call. This information may be useful to you when
you’re trying to diagnose trunking problems.
•
Queue Length
— Don’t create a queue for two-way loop-start trunks, or you may have a problem
with glare (the interference that happens when a two-way trunk is seized simultaneously at both
ends).
•
Trunk Type
— Use ground-start signaling for two-way trunks whenever possible: ground-start
signaling avoids glare and provides answer supervision from the far end. Try to use loop-start
signaling only for one-way trunks.

Adding a CO, FX, or WATS Trunk Group
Basic administration for Central Office (CO), Foreign Exchange (FX), and WATS trunk groups is
identical, so we’ve combined instructions for all 3 in the following procedure. In most cases, Avaya
recommends leaving the default settings in fields that aren’t specifically mentioned in the following
instructions. Your Avaya representative or network service provider can give you more information. Your
settings in the following fields must match your provider’s settings:
•
Direction
•
Comm Type
•
Trunk Type
CAUTION:
Use the list above as a starting point and talk to your service provider. Depending on your
particular application, you may need to coordinate additional administration with your
service provider.
Before you start
Before you can administer any trunk group, you must have one or more circuit packs of the correct type
with enough open ports to handle the number of trunks you need to add. To find out what circuit packs
you need, see the Hardware Guide for Avaya Communication Manager.
