Applications

The 7406D, 7406BIS, and 7406 Plus voice terminals can be used with the DEFINITY Communi- cation System, System 75, and System 85. These 7406 digital voice terminals are the least expensive digital voice terminals with a display that AT&T offers. Typical applications of the 7406D, the 7406BIS, and the 7406 Plus voice terminal are users who have a need for calling party display capabilities or with data terminals requiring a large number of features.

The 7406D, 7406BIS, and 7406 Plus voice terminals can also provide the user with simultaneous voice and data communications: The 7406D (7406D01A–7406D04A) are equipped with a data stand; the 7406BIS (7406D05A and 7406D06A) and the 7406 Plus (7406D07A and 7406D08A) can be connected to a 7400B Data Module. With the 7406BIS and 7406 Plus voice terminals, PC platform products can be useful in providing voice capabilities since these screen-based pro- ducts can greatly enhance the telephone capabilities of these voice terminals.
