Class of Restriction

Each extension and trunk in the system is assigned a Class of

Restriction. As its name implies, a Class of Restriction (COR) may

restrict an extension (or a trunk) from accessing an external route at

a given time.

The extension’s COR is displayed in the Source or Destination area

of the console screen, along with its Class of Service and the other

information on the caller.

Here are a few examples on how the Class of Restriction can affect

users:

• The extensions with a given COR may not dial outside the sys-

tem at all, having to ask the assistance of the attendant

to do so.

• Extensions with another COR may have to go through the atten-

dant in order to dial long distance.

• Extensions with yet another COR may only dial certain long-

distance numbers and at given times of the day.

• Extensions with the least restrictions programmed could dial

anywhere at any time.

• The extension’s COR may change with Day, Night 1 and

Night 2 services.

• Routing may change according to the time of the day and the

day of the week, indicating different outside dialing privileges

according to the time of dialing.

Class of Service

Not all the features described in this Guide are available on your

console or on other extensions.

An extension’s Class of Service (COS) appears, with the information

about that extension, in the Source or Destination area of the console

screen.

Each COS defines which features an extension or console can

activate. The message “Feature not allowed” appears on the console

screen when you try to access a feature not allowed in your or the

extension’s COS.

Here are some examples of how a COS could affect users:

• COS could change depending on whether the system is in Day,

Night 1, or Night 2 Service.

• Extensions without an appropriate COS could be denied access

to certain features, such as Call Override, Paging Access or

Setting Message Waiting Notification.

• You and other extension users may be required to enter an Ac-

count Code for additional system access or when you want to

use your COS at a different extension.

• Some extension users cannot be overridden.
