FlexSet 120S/280S User Guide
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, 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 is
field- or remotely- modifiable.
Dial
For the purpose of this guide “Dial” means entering the relevant digits by pressing
the number on the Dial Pad (Keypad) that operates a feature or sends a call to a
destination. Dial also means pressing a key programmed with the feature or
destination (DSS).
Disconnect
You may disconnect from an ongoing call by either pressing the Speaker key or by
manually replacing the handset onto its cradle (i.e. hang up).
Direct Station Selection (DSS)
Permits you to make or transfer a call to an extension by using a defined key. DSS
can also be used on all accessible system ports. Instead of dialing a number this can
be done by pressing the programmed key. Also provides busy lamp field for
programmed stations.
Digitized Voice Message
System (DVMS)
DVMS is the utility that provides the means for embedding pre-recorded
announcements into the system. Recorded messages can be informative, for
example: transfer messages, or advertisements.
