Toll Restriction
Description Toll Restriction is a system programmable feature that can prohibit
certain extension users from placing unauthorized toll calls.
Every extension is programmed to belong to one of five TRS –
Classes of Service (COS). Each Class of Service is programmed to
have a toll restriction class for the day mode, night mode and lunch
mode.
There are five toll restriction COS numbers available. Toll
restriction COS number 1 is the highest class and COS number 5 is
the lowest. COS number 1 allows all toll calls. COS numbers 2
through 5 are used to restrict calls by combining pre-programmed
deny and excepted codes.
Denied Code Classes
An outgoing outside call made by an extension with a toll
restriction COS number between 2 and 5 is first checked against the
assigned Denied Code Classes. If the first digits of the dialed
number (not including the line access code) are not found in the
class, the call can be made. There are five system programs for
Denied Code Classes: [302]–[305] Toll Restriction — Class 2 – 5
Denied Codes. Each program is used to assign denied codes for
Classes 2 through 5 respectively.
Each class can store up to 20 denied codes, each consisting of
eleven digits.
Excepted Codes
These codes are used to override a programmed denied code. A call
denied by the Denied Codes is checked against the selected
Excepted Codes. If a match is found, the call can be made.
There is one system program for excepted codes: [306] Toll
Restriction — Exception Codes. Up to eighty excepted codes,
each consisting of eleven digits, can be stored. The number of
codes available depends on the COS number.
