1.8 Toll Restriction (TRS) Features
1.8.1 Toll Restriction (TRS)
Description
Toll Restriction (TRS) can prohibit certain extension users from making unauthorised outside (CO) line calls.
Every extension is assigned to one of 5 classes of service (COSs) for each time service mode ( TRS-
COS—Day/Night/Lunch [601-603]); COS 1 grants the highest level of authorisation, allowing all outside
(CO) line calls to be made, and COS 5 grants the lowest level of authorisation. COSs 2 through 5 are used
to restrict calls with a combination of preprogrammed Denied and Exception Code Tables, explained below.
Denied Code Tables ( TRS—COS 2-5 Denied Code [302-305])
Denied Code Tables are preprogrammed lists containing the telephone numbers that are restricted. All
outgoing outside (CO) line calls made by COS 2 through 5 users are compared to the applicable Denied
Code Table(s), and when the leading number of a dialled telephone number (not including the Outside (CO)
Line Access number) matches an entry found in an applicable table, the call is denied.
Up to a total of 80 denied codes, each consisting of up to 11 digits, can be stored.
Exception Code Tables ( TRS—Exception Code [306])
Exception Code Tables are preprogrammed lists of leading digits or complete telephone numbers that are
checked against every dialled number prohibited by a Denied Code Table. When a dialled number is
prohibited by a Denied Code Table, it is compared to the applicable Exception Code Table(s). If the dialled
number matches an entry found in an applicable Exception Code Table, the call is permitted.
Up to 80 exception codes, each consisting of up to 11 digits, can be stored. The available number of codes
depends on the COS assigned to each extension.
