Setting Up Digital Trunks - Avaya Communication Manager Administrator's Manual

Managing Trunks

Setting up Digital Trunks

Any of the common trunks, except for PCOL trunks, can be analog or digital. (PCOL trunks can
only be analog.) Administering a digital trunk group is very similar to administering its analog
counterpart, but digital trunks must connect to a DS1 circuit pack and this circuit pack must be
administered separately. The example in this section shows you how to do this.
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:
Bit Rate
●
Line Coding (unless you're using a channel service unit to convert between your line
●
coding method and your provider's)
Framing Mode
●
Signaling Mode
●
Interface Companding
●

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
Assign the DS1 circuit pack before you administer the members of the associated trunk groups.

CAUTION:
If enhanced DS1 administration is not enabled, you cannot make changes to the

DS1 Circuit Pack screen before you remove related member translations of all
trunks from the trunk group. See
Before you can administer a digital trunk group, you must have one or more circuit packs that
support DS1 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,
