Port Class Configuration
This function allows you to assign a call authorization class to each port to restrict outbound calls.
There are 6 classes: A, B, C, D, E, and U. Class A has the most outbound call access capability. Class B has the second most outbound call access capability, and so on. Class U has the same meaning as OFF – there is no outbound call control.
NOTE: Class U is the default setting.
A port’s class determines its level of outbound call capability. A port that is set to class A has the most call capability, while a port set to class C is more restricted and has less call capability. The authorization classes can be defined in the Class of Service Configuration page (covered on the previous page).
