7405D Voice Terminal
The 7405D voice terminal is a multi-appearance digital voice terminal which allows features to be
added as the user needs them. The Digital Display can be added to provide access to the Mes-
sage Center. A Digital Terminal Data Module or 7400B can be added to enable the user of a
7405D voice terminal to transmit or receive data with an associated data terminal.
The basic voice terminal provides 10 call appearance/feature buttons with lights that can be
assigned to call appearances or system features. It has 24 programmable feature buttons and
six fixed feature buttons. The 7405D can also have a function key module which adds 24 feature
buttons and a call coverage module (when no display module is used) which adds 20 call
appearance/feature buttons.
The 7405D voice terminal was discontinued in February 1990, but will be supported until Febru-
ary 1996.
