Overview
Introduction
By providing internal and external users access only to the
facilities and calling privileges that their jobs require, you can
greatly decrease the potential for system abuse and toll fraud.
With Basic Access Restrictions features, you can deter internal
abuse and restrict external access to toll facilities.
The features
The Basic Access Restrictions features you can apply to
stations, TIE trunks, and authorization codes are as follows:
• Trunk Group Access Restrictions (TGAR/TARG) controls
the specific trunk groups to which a station, TIE trunk,
Direct Inward System Access (DISA) directory number, or
authorization code has direct access.
For more information, see “Trunk Group Access
Restrictions” on page 6-11.
• Class of Service (CLS) controls the degree of access; that
is, once access is provided, CLS determines whether users
can make local, TIE trunk, or long-distance calls.
For more information, see “Class of Service” on page 6-13.
