Figure 12-2. Another Version of the 8403 Voice Terminal
The 8403 voice terminal is a multi-appearance digital telephone with three call
appearance buttons, Conference, Transfer, Drop, and Hold buttons, a TEST
button, a blue FEATURE button which allows you to access 12 system features
assigned by the System Manager and to choose from among eight different
ringing patterns, a MUTE button, a SPEAKER button which accesses a 1-way,
listen-only speaker, a red Message light, and a Volume control button.
The 8403 can be used in either a 4-wire or 2-wire environment. For more
information, see the section on “Wiring Information.”
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.

Call Appearance Buttons
The 8403 voice terminal has three call appearance buttons. Each of the buttons
has a red light and a green status light.
Message Light
The red Message light goes on when a message is left for the user. It goes off
when the user retrieves the message or when the message is erased. This light is
labeled either
Messageor .
SPEAKER Button
The 8403 voice terminal is set for the 1-way, listen-only Speaker feature. The user
can only listen to the far-end. To speak with the other party, the user must use the
handset which turns off the speaker.
MUTE button
The MUTE button is a fixed feature button with a red status light. The MUTE
button turns off the microphone of the handset so that a person can converse with
another person in the room without the other par ty listening in.
VOLUME Control button
The 8403 voice terminal has a VOLUME “arrow” button on the front of the set.
This button has several functions. When the user is using the 1-way speaker, the
VOLUME button controls the volume of the speaker. When the user is on a call
using the handset, the VOLUME button controls the volume of the handset. When
the voice terminal is idle, the button controls the volume of the tone ringer.
TEST Button
When the voice terminal is initially powered up, the green light next to the TEST
button flashes if the link with the PBX is not (or not yet) operational. The light
changes to steady green when the voice terminal is able to communicate with the
PBX. After the voice terminal is powered up, you can press the TEST button to
test the lights on your voice terminal.
Other Physical Features
Handset
The 8403 voice terminal is equipped with a K-type handset.
Dial pad
The 8403 voice terminal is equipped with a 12-button touch-tone dial pad. The
letters “Q” and “Z” have been added to the appropriate dial pad keys for directory
access, and the “5” button on the dial pad has raised bars for visually-impaired
users.

Jacks
The 8403 voice terminal’s housing has a Line jack and a Handset cord jack
located on the back of the housing. There is also a Speakerphone/headset
adapter jack on the back of the set to which the user can connect adjunct
equipment.
Cords
Two cords are supplied with the 8403: a coiled 9-foot handset cord and a 7-foot
line cord.
Optional longer cords are available: a 12-foot handset cord and 14-foot and
25-foot line cords.
Ringing
The 8403 voice terminal has electronic tone ringing. With the Select Ring feature,
the user can choose any one of eight different ringing patterns. The set has a
Volume control button which controls the loudness of the ringer, the speaker, and
the handset.
Mounting Options
The 8403 voice terminal comes equipped with a nonadjustable desk stand.
However, the user may choose to remove the stand and then mount the voice
terminal on the wall.
Color Options
The 8403 voice terminal is available in black and in white.
Wiring Information
The 8403 voice terminal works in both 4-wire and 2-wire DCP configurations. The
table below describes the pins on an 8400-Series voice terminal LINE jack.

NOTE:
Regardless of which configuration is in use, ALL wiring between the PBX
and the terminal MUST consist of twisted-pairs, including the modular line
cord. The line cord must be a D8W, which consists of 4 twisted-pairs, or a
Lucent Technologies-approved equivalent.
Twisted-pair wiring is used to make lines less sensitive to crosstalk.
Therefore, failure to use twisted pair wiring may result in less-than-optimum
performance of the terminal and may also contribute to problems with the
line.
An 8-wire modular cord MUST be used for all 4-wire and any 2-wire
installations requiring auxiliary power.
NOTE:
You do NOT need to change any settings on the voice terminal for 2-wire or
4-wire installations. The voice terminal is able to detect whether it is in a
2-wire or a 4-wire configuration.
For 2-wire operation, if you need to plug the voice terminal into a 4-pin or
6-pin wall jack, instead of a standard 8-pin modular jack, refer to the “Line
Interface” table to insure that the wires from the 4-pin or 6-pin wall jack are
connected to the correct pins on the terminal “LINE” jack.
In order for the terminal to function properly in either 2-wire or 4-wire
installations, there must be NO INTERCONNECTIONS between the wire
pairs used for 2-wire and 4-wire operations. Bridging or paralleling of these
pairs can result in damage to the terminal or can cause the PBX circuit pack
to remove power to the terminal.
REMOVE ALL CONNECTIONS BETWEEN PAIRS BEFORE
CONNECTING THE TERMINAL.
4-WIRE installations MUST ONLY have PBX connections on pair 2 and pair
3 and, if necessary, auxiliary power must be connected to pair 4.
2-WIRE installations MUST ONLY have PBX connections on pair 1 and, if
necessary, auxiliary power must be connected to pair 4. 6 3 ID2 4-Wire Input

Distance Limitations
The following circuit packs can be used with all of the 8400-Series sets.
In 4-wire operation, the voice terminal must be within 5,000 feet of the PBX using
22-gauge or 24-gauge wire, and within 4,000 feet of the PBX using 26-gauge wire.
In 2-wire operation, the voice terminal must be within 5,500 feet of the PBX using
22-gauge wire, within 3,500 feet of the PBX using 24-gauge wire, and within 2,200
feet of the PBX using 26-gauge wire.
Power Requirements
The 8403 voice terminal receives power from the system and does not require any
external power supply. Additional external power IS required when the 8403 voice
terminal is equipped with any adjuncts, such as an external speakerphone. In this
instance, an 1151A1 local power supply or an 1151A2 power supply with Battery
Holdover is recommended. Refer to theAdjunct Powersection earlier in this
manual for more information about these power supplies.
