Access Code Number A series of digits, which must be dialed to gain access to an outside line or a
Coral feature.
Central Office (CO) Area switching facility serving customers in a defined geographical location.
Class of Service
(COS)
A class-of-service (COS) consists of a list of features that are available to the
telephone line user. However, the user may be denied certain features. Each
internal telephone is marked with two classes-of-service, Primary and
Secondary, which can be defined differently. In order to increase flexibility,
Coral allows switching between the Primary and Secondary COS, but only one
COS can be utilized at a time. When the telephone is in check-out mode the
telephone is marked by a system-wide defined COS and the user is denied this
feature (see
page 106) .
