The MERLIN Plus Communications System

 

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

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."

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. 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.

5-Button

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.
