Chapter 6 Trunking

Toll Restriction

The toll code restriction data allows the system administrator to program certain restrictions for Tandem (trunk-to-trunk) and Outgoing calls. Outgoing toll restriction is based on a station RSC. For outgoing, the parameters request the Route Number, Destination Code, RSC, and Toll Data Index (TDI). The TDI can be assigned as; Connection is restricted, Connection is allowed, 3/6 Digit toll restriction, or C.O operator call. When 3/6 Digit toll restriction is used, the system will ask what digit to check the restriction upon (3rd or 6th).

3/6 Digit Toll Restriction

3/6 Digit Toll allows restrictions to be assigned starting with a specific digit place in the dialed number. This command will request the Route Number, RSC, Digit Code (3 or 6 digits), and whether it is allowed or restricted. For example, if I wish to restrict stations with an RSC of "4" from dialing 555 numbers only if a specific route (Route n) gets chosen in the LCR sequence: In the Toll Restriction data, assignment would be to check the 6th digit (9 + 1 + 201 + 5XX + XXXX). In the 3/6 digit toll table assign Route n, RSC4, DC 555, RES: 0 [restricted].

Priority Restriction Class

These provide 8 levels of control over a user's route access eligibility. The system allows a call to reach its destination if the RSC is greater than or equal to the Priority Restriction Class of the outgoing trunk group (route).
