Assign Entries To Toll Restriction Tables

Description: Plan and execute system toll restriction in the sequence detailed in the following steps.
1. Determine the types of dialing restrictions that you wish imposed on the system.

the dialing of numbers entered in a DENY table. ALLOW tables take precedence
over DENY tables. Therefore, an entry in an allow table will provide an explicit
exception to an entry in a DENY table. Note that the system always permits the
dialing of any number not explicitly denied. Also, note that the system will not toll

separate programming step.
Example A: Provide a simple and broad toll restriction format by creating a DENY
table with two entries: ENTRY (1) = 1; ENTRY (2) = 0. This format prevents all
long distance and operator calls.
Example B: Prevent the dialing of all numbers within the (804) area code, while
allowing the dialing of one specific number within that area code. by entering 1804
in a DENY table and 18049782200 in an ALLOW table.
one entry. The # character is a "match-anything" digit, and can be included in an
entry in either a DENY table or an ALLOW table.
Example A: If 357, 377, 387, and 397 dialing is to be prohibited, list one entry of
3#7 on a DENY table to cover them all.
Example B: Since area codes typically have a 1 or a 0 as a middle digit, prevent
long distance calls to those area codes by entering 1#1# and 1#0# in an DENY table.

assigns them to the lines. You need only to assign them the stations to put them into
effect. The preprogrammed values are as follows:
Table 3–10: Default Toll Restrictions
Table 1 = Deny
Entry 1 = 1
Entry 2 = 976
Entry 3 = 411
Entry 4 = 0
Table 2 = Allow
Entry 1 = 1800
Entry 2 = 911
