Your 7406BIS Voice Terminal
The 7406BIS voice terminal is available in two models: one with a display and one
without a display. The display adds some functionality, but both models are designed
so that you can conveniently use the features of the AT&T DEFINITY®
Communications System Generic 2 and System 85.
The 7406BIS voice terminal also offers a high-quality, built-in speakerphone. You can
use the speakerphone for placing and answering calls or for using voice features
without lifting your handset, and for allowing others to participate in your telephone
conversations.
Note: For best sound quality, place your voice terminal flat on your desk or other
working area.
The display-equipped 7406BIS voice terminal is shown and explained on the following
pages. Both models (with display and without display) have the same button layout.

A Quick Look at the Features
Here are brief descriptions of some features, including what each one does and how
you might want to use it. The first features are voice features followed by display
features. You will have the Conference, Drop, Hold, Message, Mute, Select Ring, Self-
Test, Shift, and Transfer voice features, and Message Retrieval and Normal display
features. In addition, you may have many of the other features listed here; your
System Manager can advise you.
Voice Features
Abbreviated Dialing (AD) Allows you to store selected telephone numbers as 3 or
fewer digits for quick and easy dialing. Each number can be a complete or partial
telephone number, an extension number, or a trunk or feature code. There are 3
possible types of lists — personal, group, and system — and you can have a total of 3
lists. Numbers on a personal list are programmable by you; numbers on all other lists
are programmable only by the System Manager. Use this feature as a timesaver for
dialing frequently called, lengthy, or emergency numbers. Note: Check with your
System Manager for the types of lists you have and how many of each.
Automatic Callback Sends you a special 3-burst ring tone indicating that a
previously busy extension is now available. Use to avoid constant redialing when you
want to speak to someone who is frequently busy on the telephone. Note: You can
use this feature only for extensions, not outside numbers.

Bridging Permits you to answer or join calls to someone else’s extension by pressing
a bridged appearance button on your voice terminal. This button can be any call
appearance labeled with another user’s primary extension number, as assigned to you
by your System Manager. Use to assist in handling calls for a designated coworker.
Call Coverage Provides automatic redirection of certain calls to your voice terminal
for answering. (Your System Manager determines which calls will be sent to you.)
Use to answer calls for other extensions for whom you provide coverage. Call
Coverage can also automatically redirect your calls when your voice terminal is busy,
you are out of the office, or you have pressed the Send All Calls button.
Call Forwarding — Busy/Don’t Answer Temporarily forwards all your calls to
another extension or to the attendant if your voice terminal is busy or you do not
answer your calls within a preset number of rings. Use when you want your calls to
be forwarded to a telephone number of your choice.
Call Forwarding — Follow Me Temporarily forwards all your calls to another
extension or to an outside number, depending on your system. Use when you want
your calls to be automatically forwarded to a telephone number of your choice.
Call Park Puts a call on hold at your voice terminal, for retrieval at any extension.
Use when you need to go elsewhere to get information during a call, or whenever you
want to complete a call from a different location. Also, if the call received is for
someone else, use it to hold the call until the called party can answer from the nearest
available voice terminal.

Call Pickup Lets you answer a call at your voice terminal for another extension in
your pickup group. Use when you want to handle a call for a group member who is
absent or otherwise unable to answer. Note: You can use this feature only if you and
the called party have been assigned to the same pickup group by your System
Manager.
Conference Allows you to add a third party to a call, so that you can conduct a 3-
way conversation. (If you want to conference more than 3 parties, call your attendant
for assistance.) Use to set up time-saving conferences, or to spontaneously include a
third party important to a discussion.
Drop Disconnects from a call without requiring you to hang up the handset or press
the switchhook. Can also be used with the Conference feature to disconnect the last
party added. Use whenever you want to continue using the handset for another action
after ending a call.
Hold Puts a call in a holding state until you can return to it. While a call is on hold,
you can place another call, activate another feature, answer a waiting call, or leave
your voice terminal to do another task. Use when you have a call that you don’t want
to drop, but have to interrupt briefly to do something else.
Intercom (Automatic/Dial) Gives you quick access to specified voice terminals. With
Automatic Intercom, you can call predetermined persons, by pressing a single feature
button. With Dial Intercom, you can call any member of a predetermined group by
pressing a feature button and then dialing the group member’s 2- or 3-digit code.

Last Number Dialed Automatically redials the last number you dialed, either an
extension or an outside number. Use to save time in redialing a busy or unanswered
number. Available with DEFINITY Generic 2 and System 85 R2V4 and some R2V3
systems. Check with your System Manager to see if the feature is available in your
system.
Leave Word Calling (LWC) Leaves a message for another extension to call you back.
The called party will be able to dial message center, AUDIX, or a covering user to
retrieve a short, standard message that gives your name and extension, the date and
time you called, and the number of times you called. Use any time you want to have
someone call you back; it will help cut down on repeated call attempts.
Message Retrieval Lets you know that a caller has left a message for you when the
message light goes on. You can then follow your System Manager’s local message
retrieval procedures to get your message. See the Message Retrieval procedures
under the Display Features heading.
Mute
Allows you to turn off the microphone of the speakerphone or the handset so
that the caller cannot hear you.
Priority Calling Allows you to call another extension with a distinctive 3-burst ring
to indicate that your call requires immediate attention. Use when you have important
or timely information for someone.
Select Ring Allows you to select your own personalized ring from among 8
available ringing patterns. Use to distinguish your ring from that of other nearby
voice terminals.

Self-Test Allows you to test the operation of the lights and ringer of your voice
terminal.
Send All Calls Temporarily sends all your calls to the extension of a person
designated to answer them when you cannot (perhaps a secretary or receptionist). Use
when you will be away from your desk for awhile, or when you do not want to be
interrupted by telephone calls.
Shift Allows you to access the top-labeled features on split-labeled, shiftable buttons,
including Select Ring. Use whenever you need to access one of these features.
Speaker Allows you to place calls or access other voice features without lifting the
handset. However, in order to speak to the other party, you must lift the handset.
Use with features that require listening only, such as on-hook dialing, monitoring calls,
on hold, and group listening situations. Note: Your voice terminal has either the
Speaker (listen-only) or the Speakerphone function. Check with the System Manager.
Speakerphone Allows you to place calls or access other voice features without lifting
the handset. Use any time you prefer hands-free communication, both speaking and
listening or for group listening. Note: Your voice terminal may be set for the Speaker
(listen-only) feature. Check with the System Manager.
Terminal Busy Indication Provides a visual indication of the busy (off-hook) or idle
(on-hook) status of a specified voice terminal. Use this information when servicing
calls for another person. For example, if you are a secretary servicing your
supervisor’s calls, use this feature to see whether your supervisor’s extension is busy
or idle.

Transfer Transfers a call from your voice terminal to another extension or outside
number. Use when your caller needs to speak further with someone else. Note: Calls
from an outside number to your voice terminal can be transferred only to an extension,
not to another outside number.
Display Features
Note: These features can be used only with a 7406D05A voice terminal, the 7406BIS
voice terminal with a display.
Inspect Shows you call-related information for an incoming call when you are
already active on a call. Use to identify and screen new calls.
Message Retrieval Allows you to retrieve messages left for you that have lit your
message light. Will also let you retrieve messages for other voice terminals not
equipped with a display (if you are authorized as a systemwide message retriever by
your System Manager). Use to quickly and conveniently check messages, even when
you are already on a call.
Normal Identifies current call appearance, calling/called party, and calling/called
number. Use to see who is calling you and, when placing a call, to verify the number
you have dialed.
Time Shows you the date and time, and with the Elapsed Timer button, allows you
to measure elapsed time. Use as a handy calendar and clock, and to keep track of time
spent on a call or task.

How to Use the Features
Many features are available for use with your 7406BIS voice terminal. Because no
organization can use all of the available features, each organization must choose those
that best suit its needs. After the choices have been made, the person within your
organization who manages your telecommunication system must do any necessary
administration and label the feature buttons on individual voice terminals. This
System Manager can tell you how to use the features that have been administer for
your particular voice terminal. The procedures that follow give instructions for using
some of the more frequently used features. Features are listed alphabetically.
Special Instructions
The first time you use these procedures, you will need to customize them for yourself.
Your System Manager can supply the information required.
●To the right of each feature name is a box. For each feature that you have, mark a
[ ✓] in the box if the box is blank. Voice features (Conference, Drop, Hold, Message,
Mute, Select Ring, Speakerphone, and Transfer) and display features (Message
Retrieval and Normal) are already marked for you.
●To use a voice feature you must have the handset off-hook (that is, you must pick up the
handset or turn on the speakerphone, if you have one) unless you are instructed to remain
on-hook in the procedures. You can activate and cancel most of the voice features by
dialing 2- or 3-digit codes (if they are not already assigned to a button). Write the
feature code numbers in the blanks provided within the procedures. These codes
are unique to your system; see your System Manager for the codes or to obtain more
information.

●
System 85 exists in several versions. In some cases, a feature operates differently
with one version than it does with another; where this occurs, the procedures
include a release (R) and version (V) notation. Be sure to follow the directions
corresponding to the release and version you are using. Ask your System Manager
if you do not know the release and version you have.
Note: You must press [ Shift ] before you use any of the top-labeled features on
shiftable buttons. Also, if you receive an intercept tone (high-pitched, alternating high
and low tone) while attempting to operate any feature, you have taken too much time
to complete a step, have made a dialing error, or do not have the feature available to
you. If appropriate, hang up or press [ Drop ], get dial tone, and begin at the first step.
Conventions
The following conventions are used in the procedures:
Italic procedure steps Procedural steps in italic type are steps that you should
follow if you do not have a button assigned for the
feature.
[ xxxxx ] A box representing a call appearance that is used
exclusively for placing, receiving, or holding calls.

DISPLAY INFORMATION ]
[feedback tone]
Boxes representing buttons that have features assigned
to them. The buttons are labeled with the feature name,
sometimes followed by an extension number or a
person’s name.
A box containing fully capitalized words represents
information shown on the display.
The tone appearing in brackets after a step indicates
what you hear after successfully performing that step.
For more information, see Tones and Their Meanings and Key Words to Know at the
end of this guide.
Quick-Reference Lists
At the end of this guide is a set of quick-reference lists. Use the lists to record your
feature and trunk codes, Abbreviated Dialing personal list items, and frequently called
miscellaneous extensions. Once you have completed the lists, flip to that page as
needed, or make a photocopy and keep it handy.

Voice Features
Note: When placing and answering calls or using the voice features, you have the
option of doing so by lifting the handset or by pressing the Speaker button. If your
voice terminal is set for the Speakerphone feature, pressing the Speaker button
simultaneously activates the built-in microphone so that you can place and answer calls
without lifting the handset.
Abbreviated Dialing (AD)
Note: If you hear the intercept tone while programming,. start over from the
beginning. Abbreviated Dialing buttons must first be assigned by your System
Manager.
