The MERLIN Plus Communications System
THE CONTROL UNIT
THE VOICE TERMINALS
5-Button
The basic MERLIN Plus system supports up to four outside telephone lines
and eight voice terminals (MERLIN system telephones). To accommodate
your growing communications needs, the system expands easily and
economically to support up to eight outside lines and 20 voice terminals. And
if your business eventually outgrows even the fully expanded MERLIN Plus
system, you can protect your investment in voice terminals, accessory
equipment, and training time by moving up to a larger MERLIN system.
The paragraphs that follow offer a brief introduction to the system's control
unit and voice terminals. The optional equipment you can add to your system
is described under the heading "Accessory Equipment" in Section 5,
"Reference."
The control unit is the system's brain. It manages all incoming, outgoing, and
intercom call traffic. It makes all of the system's decisions and controls all of
the system's responses. For an illustration of the control until with its major
components labeled, see "Administration Preview" in Section 3,
"Administering the System."
A voice terminal is a MERLIN system telephone that provides basic telephone
functions and allows you to take advantage of the special MERLIN system
features. Your MERLIN Plus system works best with the following voice
terminals:
5-Button Voice Terminal
10-Button Voice Terminal
10-Button Hands-Free Answer on Intercom (HFAI) Voice Terminal
34-Button Deluxe Voice Terminal
34-Button Built-In Speakerphone (BIS) Voice Terminal.
All of these voice terminals have buttons for fixed features such as
Conference, Drop, Transfer, and Hold. They differ from one another in the
number of buttons above and to the right of the dial pad that can be used for
outside lines and programmable features. Some also have additional built-in
speakerphones. The illustrations that follow should help acquaint you with
these voice terminals.
The 5-button voice terminal has an Intercom button and four additional
buttons above the dial pad that you can use for outside lines and/or
programmable features.
