General FeaturesFeatures Guide 183Toll RestrictionDescriptionToll Restriction is a system programmable feature that, in conjunction with the assigned Classof Service, can prohibit certain extension users from placing unauthorized toll calls.Every extension is programmed to belong to one of 96 Classes of Service. Each Class ofService is programmed to have a toll restriction level for day mode and night moderespectively.There are eight toll restriction levels available. Toll restriction level 1 is the highest level andthe level 8 is the lowest. That is, level 1 allows all toll calls and levels 7 and 8 disallow all tollcalls. Levels 2 through 6 are used to restrict calls by combining pre-programmed deny andexcepted code tables.TRS Deny Code TablesAn outgoing CO call made by an extension user with a toll restriction level between 2 and 6 isfirst checked against the selected TRS Deny Code Tables. If the leading digits of the dialednumber (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 CodeTable for Levels 2 through 6 respectively.Complete every table by storing numbers that are to be prohibited. These numbers are definedas deny codes. Up to 400 deny codes (max.10 digits for each) can be stored for TRS Levels 2through 6.TRS Exception Code TablesThese tables are used to override a programmed deny code. A call denied by the selected TRSDeny Code Tables is checked against the selected TRS Exception Code Tables, and if a matchis found, the call is made.System Programming, Toll Restriction - TRS Exception is used to make up a TRSException Code Table for Levels 2 through 6. Complete every table by storing numbers thatare exceptions to the TRS deny codes. These numbers are defined as exception codes. Up to200 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 restrictionlevel of an extension as follows:TRS Deny Code Tables TRS Exception Code TablesLevel 1 None NoneLevel 2 Table for Level 2 Tables for Levels 2 - 6Level 3 Tables for Levels 2 and 3 Tables for Levels 3 - 6Level 4 Tables for Levels 2 to 4 Tables for Levels 4 - 6Level 5 Tables for Levels 2 to 5 Tables for Levels 5 - 6Level 6 Tables for Levels 2 to 6 Tables for Level 6Level 7 None None
