This field appears only for a DID trunk group and is used only with the TN459A circuit pack. Enter y or
n depending on the distance between the central office and your server. If greater than the required
distance, then the field should be y.
Group Name
Group Number
This field displays the group number assigned when the trunk group was added.
NOTE:
For trunk groups connecting 2 media servers or switches in Distributed Communication
System networks, Avaya recommends that you assign the same group number on both
servers or switches.
Group Type
Enter the type of trunk group.
Busy-out the trunk group before you change the group type. Release the trunk group after you make the

Enter a unique name that provides information about the trunk
group. Don’t use the default entry or the group type (DID, WATS)

and function of the trunk group: USWest Local; Sprint Toll, etc.

Usage
Access
Use access trunks to connect satellite media servers or switches to the main switch
in Electronic Tandem Networks (ETN). Access trunks do not carry traveling class
marks (TCM) and thus allow satellite callers unrestricted access to out-dial trunks
on the main server. Allows Inband ANI.
APLT
Advanced Private Line Termination (APLT) trunks are used in private networks.
APLT trunks allow inband ANI.
CAMA
CAMA trunks route emergency calls to the local community’s Enhanced 911
systems.
CO
CO trunks typically connect Communication Manager to the local central office,
but they can also connect adjuncts such as external paging systems and data
modules.
