The 7400 Series Voice Terminals
11-3 The 7401D and 7401 Plus Voice Terminals
11
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
titledSpecial 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
vir tualcall appearances
with
virtualin-use andvirtualstatus indicators. That is, to the PBX, the7401D 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.

The Automatic Line Management (ALM) feature of the 7401D or 7401 Plus voice
terminal automatically selects one of the two
vir tualcall appearances when the
user goes off-hook either by the user’s lifting the handset (on the 7401D or the
7401 Plus voice terminal) or turning on the optional speakerphone adjunct (on the
7401 Plus voice terminal). ALM follows a hierarchical algorithm. From the user’s
point of view, the hierarchical order of actions which could take place is:
1. If either of the status lights of the vir tual call appearances is flashing when
the user takes the telephone off-hook, the voice terminal will always pick-up
the “ringing” call. If both vir tual call appearances are in the flashing state,
the voice terminal will select the call that was ringing for the longer period
of time.
2. If neither of the status lights is flashing, but one is winking or fluttering when
the telephone goes off-hook, the voice terminal will automatically “un-hold”
the held call. If both vir tual call appearances are in the held state, the voice
terminal will select the call that was on hold for the longer period of time.
3. If neither of the status lights is flashing, winking, or fluttering, but one is
steady when the voice terminal goes off-hook, the voice terminal will
automatically bridge on to the busy appearance. If both vir tual call
appearances are in the steady state, the voice terminal will choose the first
virtual call appearance. (A call appearance can be in the busy state due to
another party answering the call. This can occur in conjunction with such
features as coverage, bridging or pickup.)
4. Otherwise, no special action is taken; the voice terminal will pick up an idle
virtual call appearance as determined by the PBX.

Button Numbering
The 7401 Plus (7401D02A) voice terminal can be administered in the same
manner as the 7401D (7401D01A) voice terminal. Both types of voice terminals
have 12 possible voice features; however, only seven of these features can be
administered on the voice terminal (F1 through F7 on the Feature Directory). The
remaining five features are fixed (F8, F9, F0, F#, and F* on the Feature Director y):
F8 Conference
F9 Transfer
F0 Drop
F# Hold
F* Select Ring
The following button diagrams of the 7401D and 7401 Plus voice terminals will
help you administer both of these voice terminals connected to a System 75, a
DEFINITY G1 and G3, or a DEFINITY ECS, and to a System 85 or a
DEFINITY G2.
Figures 11-2 and 11-3 show button numbering for both the 7401D and the 7401
Plus voice terminals.
NOTE:
Although these figures show the 7401 Plus set, the administration of the two
types of voice terminals is the same.
