TToll RestrictionDescription Toll Restriction is a system programmable feature that, inconjunction with the assigned Class of Service, can prohibit certainextension users from placing unauthorized toll calls.Every extension is programmed to belong to one of eight Classes ofService. Each Class of Service is programmed to have a tollrestriction level for day mode and night mode.There are eight toll restriction levels available. Toll restriction level1 is the highest level and the level 8 is the,lowest. That is, level 1allows 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 TablesAn outgoing outside call made by an extension with a tollrestriction level between 2 and 6 is first checked against theselected Denied Code Tables. If the leading digits of the dialednumber (not including the line access code) are not found in thetable, the call is made. There are five system programs for DeniedCode Tables: [301]-[305] TRS Denied Code Entry for Levels 2through 6: Each program is used to make up a Denied Code Tablefor 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 storeup to 20 denied codes, each consisting of a maximum of ten digits.Excepted Code TablesThese tables are used to override a programmed denied code. AcalI denied by the selected Denied Code Tables is checked againstthe selected Excepted Code Tables, and if a match is found, the callis 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 forLevels 2 through 6.Complete every table by storing numbers that are exceptions to thedenied codes. These numbers are defined as excepted codes. Eachtable can store up to five excepted codes, each consisting of amaximum of ten digits.Features 3-153
