Type tone in both the
Outgoing Dial Type
and
Incoming Dial Type
fields.
These fields tell Communication Manager how digits are transmitted for incoming calls. Entering
tone actually allows the trunk group to support both DTMF and rotary signals, so Avaya
recommends that you always put tone in this field.

Now you’re ready to add trunks to this trunk group. See
Adding Trunks to a Trunk Group
on page 366 for
more information.
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
Enhanced DS1 administration
on page 362.
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.
