What the Features Do

Here are brief descriptions of the features which you can use with an ISDN 8510T
voice terminal connected to a DEFINITY Communications System Generic 1 or
Generic 3. The following descriptions include what each one does and how you might
want to use it.

The features in this section are divided into 3 main categories: Fixed (Button)
Features, Display and Softkey Features, and Switch Features. Only
procedures for the last type, Switch Features, are provided in this book.

Fixed (Button) Features— These voice terminal features, such as Conference,

●

Drop, Hold, and Transfer, have been assigned to particular buttons on the voice
terminal when it is built at the factory. Thus, when you receive the voice
terminal, you can use these features immediately. Descriptions of these features
appear below and on the next page. For directions on using these features, see
the AT&T DEFINITY Communications System ISDN 8510T Voice Terminal
User’s Manual, 555-021-736.

Display and Softkey Features— The features in this category are accessed

●

with the 4 softkeys (the buttons below the display labeled with arrows, such as

▲ ] ), the 4 display control buttons (Menu, Dir, < Prev, Next >), and the

[
2-line by 40-character display. These features include a personal Directory, a
Call Log of the most recent answered and unanswered calls, and the Self-Test
feature. This section provides descriptions of the Display and Softkey features.
For procedures for using these features, see the AT&T DEFINITY

Communications System ISDN 8510T Voice Terminal User’s Manual,

555-021-736 and the AT&T DEFINITY Communications System ISDN 8510T
Voice Terminal Quick Reference Guide, 555-021-735.

●

Switch Features— You can use these features only with a DEFINITY Generic 1
or Generic 3, and if these features have been assigned to your voice terminal.
Check with your System Manager to see which of these features you can use.

Fixed (Button) Features

Conference Allows you to add an additional party to a call so that you can conduct

a conversation with more than one party. Use to set up time-saving conferences, or
to spontaneously include a party important to a discussion.

Drop Disconnects you 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 are using the handset and want to continue
using it for another action after ending a call.

Hold Temporarily disconnects you from a call, holding it 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 perform another task. Use when you
have a call that you don’t wish to drop, but for which you have to interrupt briefly to
do something else.

5

Message Retrieval Your Message light goes on to let you know that a caller has left
a message. Follow your System’s message retrieval procedures to get your message.

Mute Turns off the microphone associated with the handset or the speakerphone,
whichever is currently active. Use when you want to confer with someone in the
room with you, but you do not want the other party on the call to hear your
conversation. (You are still able to hear the person on the call.)

Redial (Last Number Dialed) Automatically redials the last number you dialed
manually from the dial pad, either an extension or an outside number. Use to save
time in redialing a busy or unanswered number.

Speakerphone Your voice terminal has either the Speaker (listen-only) or the
Speakerphone (listen and talk) function or it may have neither. Check with the
System Manager to see how your voice terminal is set.

The Speaker (listen-only) feature allows you to place calls or access other voice
features without lifting the handset. (Press [

Speaker ] .) However, in order to speak

to the other party, you must use the handset (the speaker must be off). Use with
feature activities that require listening only, such as on-hook dialing or monitoring
calls on hold.

The Speakerphone feature allows you to place and answer calls or access other voice
features without lifting the handset. (Press [

Speaker ] .) You may use the softkeys on

the voice terminal to set or reset the speakerphone. When you set the built-in
speakerphone, it performs a test of the surrounding environment and adjusts itself
for optimal performance. Use the built-in speakerphone any time you prefer hands­free communications, both speaking and listening, or for group conference situations.

Transfer Transfers a call from your voice terminal to another extension. Use when
your caller needs to speak further with someone else.

Display and Softkey Features

Call Log The Call Log is initially set to list the 10 most recent incoming

unanswered calls only. An option is provided so that you may also choose to access
the most 10 recent answered calls, and the 10 most recent outgoing calls placed from
your voice terminal. Use to check on calls that you missed (the unanswered calls)
and to remind you of those calls that you answered or placed most recently.

Clock For setting the date and time on your voice terminal display.

Contrast Change the contrast level of your display so that the letters or numbers

are darker or lighter against the background of the screen.
Directory Used to create and edit a personal directory of up to 30 extensions or

outside numbers and the names of the associated party. Use [
call. Use as a handy place to store numbers you frequently call.

Dir Button When you press [

Dir ] followed by a softkey button associated with that

Directory entry, a call is immediately placed to a telephone number. The phone
number appears on the display screen as it dials.

Exit button Exits a display feature and returns the voice terminal display to
normal call-handling mode.

Dir ] to quickly dial a

6

Lock Allows you to lock your Directory so that no one can make unauthorized
changes in it; lock your Call Log so that no one else can view your Call Log entries;
lock all of the softkeys so that no one can view or change any of the features accessed
by the softkeys.

Number of Names (on a Directory Page) Allows you to view either 4 names or
3 names + Quit on the second line of an individual Directory page. If you choose to
have 4 names on the Directory screen at one time, you can leave the Directory or
cancel calling a name in your Directory only by pressing [

Exit ] (rather than using

Quit).

Personalized Ring Allows you to select your own personalized ringing pattern from
among 8 available patterns. Use to distinguish your voice terminal’s ring from that
of other nearby voice terminals.

Screen Timing (Rate at which the Display Message is Shown) Allows you to set
the length of time the display message remains on the screen. There are 3 rates:
Slow, Medium, and Fast.

Self-Test Performs a diagnostic test of your voice terminal including the lights,
ringer, dial pad keys, and display.

Note: When you perform a self-test of the voice terminal, it clears the contents of
the Call Log and the last number dialed from Redial, and returns the volume control
to the default setting.

Set Speakerphone When you set the built-in speakerphone, it performs a test of
the surrounding environment and adjusts itself for optimal performance.
[For a description of the listen-only Speaker and Speakerphone features, see
“Fixed (Button) Features” in this section.]

Tones A confirmation tone (sequential low and high tones) is provided to let you

know a selection has been accepted; an error tone (one beep) alerts you that you
made a mistake in your softkey entries. You may choose to turn these softkey
information tones on or off.

7

Switch Features

Abbreviated Dialing Allows you to store selected telephone numbers for quick and

easy dialing. Each number can be a complete or partial voice terminal number, an
extension number, or a trunk or feature code. There are 4 possible types of lists—
personal, group, system, and enhanced—and you can have a total of 3 out of the 4
possible lists (see your System Manager for details). Numbers on a personal list are
programmable by you; numbers on all other lists are programmable only by the
System Manager. Use as a timesaver for dialing frequently called, lengthy, or
emergency numbers.

Automatic Callback Sends you a special 3-burst ringing tone indicating that a

previously busy or unanswered extension is now available. Use to avoid constant
redialing when you wish to speak to someone who is frequently busy on the voice
terminal or in and out of the office. Note: Can be used only for extensions, not
outside numbers.

Call Forwarding All Calls Temporarily forwards all your calls to another extension
or to an outside number, depending on your system. Use when you will be away
from your voice terminal and you want your calls to be forwarded to a voice terminal
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
wish 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 it 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 wish to handle a call for a group member who is
absent or otherwise unable to answer. Note: You can only use this feature if you
and the called party have been assigned to the same pickup group by your System
Manager.

Leave Word Calling Leaves a message for another extension to call you back. The
called party will be able to dial message service (for example, attendant, AUDIX,
covering user, etc.) to retrieve a short, standard message which gives your name and
extension, the date and time you called, and the number of times you called. Use
any time you wish to have someone call you back; it will help cut down on repeated
call attempts.

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.

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 wish to be
interrupted by voice terminal calls.

Voice Message Retrieval Gives you messages (via computerized voice) left for you
through Leave Word Calling or as typed by a covering user. If authorized by your
System Manager, you may also retrieve messages for one or more of your coworkers.
Use to hear all messages received while you were away.
