Appendix A: Glossary 263 T200M Series User Guide
Class Of Service (COS) A Class-of-Service (COS) consists of a list of features that are available for the
telephone line. However, individual or groups of users may be denied certain features.
Each internal telephone has two classes of service, Primary and Secondary, which can
be defined differently. In order to increase flexibility, the Coral system 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.
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 system for an internal station. (Number
listed in the local telephone directory).
Database The memory in which the ‘flexible database system information’ is stored. Programming
the database is usually carried out during installation, however, it can be modified
remotely and in the field.

digits on the keypad that either represent a destination, a feature or a command.
