1.6 Originating Features
Toll 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 unauthorised toll calls.
Every extension is programmed to belong to one of 96 Classes of Service. Each Class of
Service is programmed to have a toll restriction level for day mode and night mode
respectively.
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 disallow all toll
calls. Levels 2 through 6 are used to restrict calls by combining pre-programmed deny and
excepted code tables.
TRS Deny Code Tables
An outgoing CO call made by an extension user with a toll restriction level between 2 and 6 is
first checked against the selected TRS Deny Code Tables. If the leading digits of the dialled
number (not including the CO line access code) are not found in the table, the call is made.
System Programming, Toll Restriction -TRS Deny is used to make up a TRS Deny Code
Table for Levels 2 through 6 respectively.
Complete every table by storing numbers that are to be prohibited. These numbers are defined
as deny codes. Up to 400 deny codes (max.10 digits for each) can be stored for TRS Levels 2
through 6.
TRS Exception Code Tables
These tables are used to override a programmed deny code. A call denied by the selected TRS
Deny Code Tables is checked against the selected TRS Exception Code Tables, and if a match
is found, the call is made.
System Programming, Toll Restriction - TRS Exception is used to make up a TRS
Exception Code Table for Levels 2 through 6. Complete every table by storing numbers that
are exceptions to the TRS deny codes. These numbers are defined as exception codes. Up to
200 exception codes (max.10 digits for each) can be stored for TRS Levels 2 through 6.
Applicable TRS Deny and TRS Exception Code Tables depend on the assigned toll restriction
level of an extension as follows:
Level 1
Level 2
Level 3
Level 4
Level 5
Level 6
