Applications
The 8403 voice terminal can be used with the DEFINITY Communications System
Generic 1, Generic 2, and Generic 3, the DEFINITY ECS, System 75, and
System 85. This voice terminal is especially suitable for general office workers
with low call volumes, manufacturing, warehousing, guard and/or reception areas,
or office desks.
The 8403 voice terminal can also provide simultaneous voice and data
communications with the 7400B Plus Data Module. PC platform products can also
be useful in providing voice capabilities since these screen-based products can
greatly enhance the telephone capabilities of these basic voice terminals.
