Applications
The 7434D voice terminal can be used with the DEFINITY Communications
System Generic 1, Generic 2, and Generic 3, the DEFINITY ECS, System 75, or
System 85. It is an appropriate terminal for users who handle numerous calls and
who need button access to a wide variety of features. For example, the 7434D
voice terminal, with its large number of administrable buttons, can use the
Abbreviated Dialing feature for reaching many frequently called par ties. The
buttons of the 7434D voice terminal can also be assigned for bridging calls at
other stations. Typical users are secretaries, managers, salespeople, buyers,
answering groups, and call covering positions. The 7434D can provide
simultaneous voice and data communications via the PC/PBX connection or
7400B Data Module.

nSELECT RING button — a special fixed feature button that has two
functions:
— When used with the * dial pad key, it allows the user to select one of
eight personalized ringing patterns for incoming calls.
— When used with the DROP button, it allows the user to test the
lights, ringer, and display module (if installed) of the voice terminal.
The Select Ring test function replaces the Self-Test switch found on
most other terminals.
NOTE:
The associated Select Ring light goes on steadily when the button is
pressed to activate either function. It winks when the user is stepping
through the ringing patterns.
Administrable Buttons
The 7434D voice terminal has 34 call appearance/feature buttons (R2V1 and
R2V2 only), each equipped with a triangular red light and a square green status
light. Usually, at least three of these buttons (the top three in the leftmost column)
are administered as call appearances for the terminal’s primary extension
number, where calls are placed and answered. The rest of the buttons can be
used for more call appearances (including bridged appearances of other stations’
extensions) and features. Buttons administered for features have only their status
lights active.
Message light 
The green light goes on when a message is left for the terminal user. It goes off
when the user retrieves the message.
Other Physical Features
Handset
The 7434D voice terminal is equipped with an R-type handset.
Dial pad

terminal’s primary extension number, where calls are placed and answered. The
rest of the buttons can be used for more call appearances (including bridged
appearances of other stations’ extensions) and features. Buttons administered for
features have only their status lights active.
Seven Display Feature Buttons (with a green status light)
The 7444 has seven administrable display feature buttons, each with a green
status light. These buttons can be used for only display features, such as Inspect.
Speakerphone (Listen and Speak) Feature
The 7444 voice terminal is equipped with a built-in S201A-type speakerphone.
The Speaker phone capability allows a user to engage in a hands-free 2-way
conversation with the far-end par ty. The speakerphone can be turned off or on
with the SPEAKER/RESET SPKR button, can be muted with the MUTE button,
and the volume can be controlled with the VOLUME “arrow” button.
The SPEAKER/RESET SPKR button also allows the user to adjust the
speakerphone for optimal performance. By pressing the SELECT button and then
the SPEAKER/RESET SPKR button (if the voice terminal is set for the
Speakerphone feature), the user hears a set of tones as the speakerphone
performs an acoustic test of the environment. When the tones stop, the
speakerphone has finished adjusting itself and is ready for use. The user should
reset the speakerphone whenever the voice terminal is moved to another place
(even in the same room), whenever the green light next to the SPEAKER/RESET
SPKR button is fluttering, and in the unlikely event that the speakerphone is
making a squealing sound (in this last case, tones will not be heard during a call).
Speaker (Listen-only) Feature
The 7444 voice terminal can be optioned for the Speakerphone (listen and speak)
orthe Speaker (listen-only) feature. Use the SPEAKER/RESET SPKR button on
the front of the voice terminal for turning on and off the speaker or speakerphone.
The voice terminal is shipped with the Speakerphone setting in place, but, the
necessary DIP switch setting can be changed so that the voice terminal operates
with the Speaker feature instead. In this case, the S2 switch should be set to the
ON position, so that the voice terminal will operate with the Speaker (listen-only)
feature.
The Speaker (listen-only) capability allows a user to engage in a one-way
conversation with the far-end. Specifically, the user can only listen to the far-end;
the user is not able to transmit his voice over the speaker. To speak with the
far-end, the user must use the handset which turns off the speaker.
MUTE button
The MUTE button disables the transmitter of the speakerphone or the handset
depending on which is activated at that time. A red light next to the MUTE button
goes on when the Mute feature is activated.

VOLUME control button
The 7444 voice terminal has a VOLUME “arrow” button. This button has a double
function. When the user is on a call, the VOLUME button controls the volume of
the speaker or speakerphone, whichever is being used; when the user is not using
the speaker or speakerphone, the VOLUME control button adjusts the tone ringer.
When the user sets the volume for the speaker or speakerphone or for the tone
ringer, the display on the voice terminal shows a “bar array” that indicates the
volume setting.
Self-Test
By pressing the SELECT button and then the DROP/TEST button, the user can
initiate a test of the lights, ringer, and display on the voice terminal.
Display
The 7444 voice terminal is equipped with a built-in, 2-line, 40-character per line
vacuum fluorescent display.
