•
Dial access code (dac) — Allows you to use trunk access codes ( TAC ) and feature access codes
(FAC) in the same range. For example, you could define the group 100–199, which would allow
both FAC and TAC in that range. Dial access codes can start with any number from 1 to 9, * and
#, and contain up to 4 digits.
In our example figure, dial access codes begin with 1 and must be 3 digits long.
NOTE:
The Dial Plan Analysis Table does not allow you to enter a range specifically for trunk
access codes. However, the Trunk Group screen still allows you to assign a TAC to a
trunk group. The TAC you enter on the Trunk Group screen must match the format you
have administered for a DAC on the Dial Plan Analysis Table.
•
Extensions (ext) — Defines extension ranges that can be used on your system. In our figure,
extensions must be in the ranges 30000–39999, 40000–49999 and 50000–59999.
•
Feature access codes (fac) only — FAC can be any number from 1 to 9 and contain up to 4 digits.
You can use * or #, but only as a first digit. In our example, feature access codes can begin with *
or # and are 3-digits long.
The Dial Plan Analysis Table works with the Dial Plan Parameters Table for fully defining your dial
plan. The Dial Plan Parameters Table allows you to set system-wide parameters for your dial plan.

Modifying your dial plan
It is easy to make changes to your dial plan. For example, we will add a new range of dial access codes to
the dial plan. We want to be able to assign both FAC and TAC in the 700–799 range.

Adding extension ranges
You may find that as your needs grow you want a new set of extensions. Before you can assign a station
to an extension, the extension must belong to a range that is defined in the dial plan. We will add a new
set of extensions that start with 3 and are 4 digits long (3000–3999).
