Now program the 3/6 digit toll restriction plan
according to the Table 1 and Table 2 using "Area/
Office Code Table."
In some areas, the same 3-digit code may be
used as both an Area Code and Office Code.

1 – 201 – NXX – XXXX, 201 – XXXX
Therefore, assign restriction level for an Area
Code in "AL" field and an Office Code in "OL" field
respectively as shown below.

(2)Programming the 3/6 Digit Toll Restriction
Plan Using "OC" field.
When you want to restrict an outgoing call for
certain area except a district within that area,
program the toll restriction plan by entering Office
Code Table No. in "OC" field of that Area Code
and set Office Code of the destrict in that Office
Code Table.
Assuming that your system is located in Area A
AC=200, and Restriction Level of Area B is set to
"10."
So extension users with TRLE of 11-16 are
restricted to place a call to Area B.

AC=200
OC=323 OC=321
