Applications

The 7407D, Enhanced 7407D, and 7407 Plus voice terminals can be used with the DEFINITY Communications System G1, G2, G3, System 75, and System 85. Typical applications of the 7407D, Enhanced 7407D, and the 7407 Plus voice terminal are managers, executives, or secre- taries who need the robust, 2-line by 40-character display capability or with data terminals requir- ing a large number of features and lines.

Special Operational Characteristics

The 7407D (7407D01B) voice terminal has an R1/R2 single-option toggle switch on the back of the stand; the Enhanced 7407D (7407D02C), and 7407 Plus (7407D02D) voice terminals have a 3-option DIP switch that can be accessed from the back of the stand, although, on both voice ter- minals only two of the options can be used. The DIP switch options can be changed with a sim- ple tool.

Switch Options for the 7407D and Enhanced 7407D

The following list describes the settings on the toggle switch on the 7407D (7407D01B) voice ter- minal and the DIP switch settings on the Enhanced 7407D (7407D02C) voice terminals:

Since the 7407D and the Enhanced 7407D have 2-line displays, the single-option R1/R2 toggle switch on the 7407D voice terminal and Switch 1 on the DIP switch settings on the Enhanced 7407D voice terminal must be activated according to the vintage of the sup- porting PBX.

The 7407D voice terminal option switch is shipped in the OFF position; the Enhanced 7407D voice terminal is shipped with Switch 1 in the R2 position. These positions are the correct setting for most PBX’s.
