Toll Restriction
Description:
Toll Restriction determines extension’s ability to make calls. Each extension can be
assigned on of the following six classes per mode (Day/Night). Toll Restriction Class A is the
highest and the Class F is the lowest.
Class-A: No dialling restrictions.
Class-B: Dials are restricted by DATA-B except dials matching PBX extension call or
DATA-F.
Class-C: Dials are restricted by DATA-D2 except dials matching PBX extension call,
DATA-C, or DATA-F.
Class-D: Dials are restricted by DATA-D2 or DATA-D1 except dials matching PBX
extension call or DATA-F.
Class-E: Dials are restricted all outgoing Trunk calls except dials matching PBX extension
call or DATA-F.
Class-F: Intercom calls only.
The DATA (restricted/permitted codes and number length limit) within the Classes must be
entered in programming.
If there are PBX lies, PBX access code must be assigned in programming in order for Toll
Restriction to be properly applied.
Toll restrictions are not applied to lines programmed as Unrestricted Lines.
When the system is placed in night mode by Night Service feature, the Toll Restriction class
assignment for night mode is activated.
Station Application:
KTS, SLT
Operation:
When an extension user dials a call that is not allowed by the assigned Class, the system
automatically disconnects the line.
