oll Restriction
Description
Toll Restriction is a system programmable feature that, in
conjunction with the assigned Class of Service, can prohibit certain
extension users from placing unauthorized toll calls.
Every extension is programmed to belong to one of eight Classes of
Service. Each Class of Service is programmed to have a toll
restriction level for day mode and night mode.
There are eight toll restriction levels available. Toll restriction level
1 is the highest level and the level 8 is the lowest. That is, level 1
allows all toll calls and levels 7 and 8 disallows all toll calls.
Levels 2 through 6 are used to restrict calls by combining pre-
programmed deny and excepted code tables.
Denied Code Tables
An outgoing outside call made by an extension with a toll
restriction level between 2 and 6 is first checked against the
selected Denied Code Tables. If the leading digits of the dialed
number (not including the line access code) are not found in the
table, the call is made. There are five system programs for Denied
Code Tables: [301]-[305] TRS Denied Code Entry for Levels 2
through 6: Each program is used to make up a Denied Code Table
for Levels 2 through 6 respectively.
Complete every table by storing numbers that are to be prohibited.
These numbers are defined as denied codes. Each table can store
up to 20 denied codes, each consisting of a maximum of ten digits.
Excepted Code Tables
These tables are used to override a programmed denied code. A
call denied by the selected Denied Code Tables is checked against
the selected Excepted Code Tables, and if a match is found, the call
is made.
There are five system programs for these tables:
[306]-[310] TRS Excepted Code Entry for Levels 2 through 6:
Each program is used to make up an Excepted Code Table for
Levels 2 through 6.
Complete every table by storing numbers that are exceptions to the
denied codes. These numbers are defined as excepted codes. Each
table can store up to five excepted codes, each consisting of a
maximum of ten digits.
