■ Dial access codes (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 600–699 for DAC, which would allow both FAC and TAC
in that range. Dial access codes can start with any number from 1 to 9 and
contain up to 4 digits, * and #. In our example figure, dial access codes
begin with 6 and must be 3 digits long, so this company can have a feature
access code set to 633 and a trunk access code assigned to 634.
■ Extensions (ext) — Defines extension ranges that can be used on your
system. In our figure, extensions must be in the ranges: 1000–1999,
2000–2999, and 5000–5999.
■ 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, this company can use *21 to activate a feature and use #21 to
deactivate the same feature. Our example also shows that one FAC can be
set to 9 (first digit 9, only one digit long).
■ Miscellaneous code (misc) — these codes are used if you want to have
more than one kind of code start with the same digit. Using a misc code
requires that you also define a second digit table. Refer to
‘‘ Second Digit
Table ’’ on page 874 for information. Our example does not show this type of
code.

You might want to take this opportunity to look at and interpret your own dial
plan. To display your system’s dial plan:

Modifying your dial plan
It is easy to make changes to your dial plan. For example, let’s 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.
1. Type
change dialplan and press RETURN.
The Dial Plan Record
screen appears.
2. Move the cursor to the 7th row in the 3rd column.
This field defines what the system does when users dial any number from
700 to 799.
3. Type
dac in the selected field.
4. Press
