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
”Class Of Service (COS)
Switchover” on page 45
).
CO Trunk Number
(Incoming)
The number that is dialed by an outside telephone user from the public network (through the
Central Office) in order to call into the Coral for an internal station. (Number listed in the local
telephone directory).
