The MERLIN Plus Communications System
THE CONTROL UNIT
The basic MERLIN Plus system provides connections to up to four outside
telephone lines and ten voice terminals. We use the term “voice terminal”
instead of “telephone” because a basic telephone only lets you make and receive
calls, while a voice terminal can be programmed to do a whole lot more, which
you will soon discover as you read this manual.
To accommodate your growing communications needs, the system expands
easily and economically to support up to eight outside lines and 20 voice
terminals. 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 with the purchase of 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 unit with its major
components labeled, see “Administration Preview” in Section 3,
“Administering the System.”
THE VOICE TERMINALS
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. All 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. The 10-button voice terminal with the “HFAI”
designation has the hands-free intercom feature. Voice terminals with “SP” or
“BIS” designations also have the hands-free answer on intercom feature and a
built-in speakerphone. For more information on using basic telephones with the
MERLIN Plus system, see “Basic Telephones” in Section 5, “Reference.”
