The 7401D (7401D01A) and the 7401 Plus (7401D02A, the newest 7401 set) are
both single appearance digital voice terminals which have no call appearance
buttons or lights, but have two virtual call appearances (refer to the section below
titled Special Operational Characteristics). The user answers a call by going
off-hook. The second appearance is primarily used with the Conference and
Transfer features. However, it can be used to originate an outgoing call or receive
a second incoming call. Depending on how the 7401D or the 7401 Plus voice
terminal is administered, the second call appearance may be restricted to
incoming priority calls and outgoing calls only.
NOTE:
The 7401D01A is no longer being manufactured. The 7401D02A (7401
Plus) was discontinued January, 1995.
Applications
The 7401D (7401D01A) and the 7401 Plus (7401D02A) voice terminals can be
used with the DEFINITY Communications System Generic 1, Generic 2, and
Generic 3, the DEFINITY ECS, System 75, and System 85. These voice terminals
are especially suitable for general office workers with low call volumes,
manufacturing, warehousing, guard and/or reception areas, or office desks.
The 7401D and 7401 Plus voice terminals can also provide simultaneous voice
and data communications with the 7400B 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.
Special Operational Characteristics
The 7401D (7401D01A) and 7401 Plus (7401D02A) do not have traditional call
appearance buttons with indicators. To the user, these voice terminals appear to
be single call appearance sets. However, there are two
virtual
call appearances
with
virtual
in-use and
virtual
status indicators. That is, to the PBX, the 7401D and
7401 Plus voice terminals appear to be a two call appearance set. These call
appearances are necessary to provide the Conference, Transfer, and Hold
features.
