							What the Features Do
Here are brief descriptions of the features which you can use with an ISDN 8520T
voice/data 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 three main categories: Fixed (Button)
Features, Display and Softkey Features, and Switch Features. Only
procedures for the last type, Switch Features, are provided in this guide.
lFixed (Button) Features—  These voice/data terminal features, such as
Conference, Drop, Hold, and Transfer, have been assigned to particular buttons
on the voice/data terminal when it is built at the factory. Thus, when you receive
the voice/data 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 DEFINITY Communications System ISDN 8520T Voice/Data
Terminal User’s Manual, 555-021-758.
lDisplay and Softkey Features— The features in this category are accessed
with the 10 softkeys (the unlabeled buttons on either side of the display), the four
display control buttons ( [ Menu ], [ Dir ], [ ¬  ¬ Prev ] , [ Next ® ® ] ), and the 7-line
by 24-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 8520T Voice/Data Terminal User’s Manual (555-021-758).
lSwitch 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/data
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 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.
DropDisconnects 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.
Exit
Exits a display feature and returns you to the Home Screen that you have
selected. The top two lines again show you the time and date and any relevant
system information.
HoldTemporarily 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/data 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.

							Message RetrievalYour 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.
SpeakerphoneYour voice/data 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/data terminal is set.
The Speaker (listen-only) feature allows you to place calls or access other voice/data
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/data features without lifting the handset. (Press 
[ Speaker ] .) You may use the
softkeys on the voice/data 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 hands-free communications, both speaking and listening, or for group
conference situations.
Transfer Transfers a call from your voice/data terminal to another extension. Use
when your caller needs to speak further with someone else.
Display and Softkey Features
The following features can be accessed using the 10 softkeys located on both sides of
the display.
Call LogThe Call Log is initially set to list the 20 most recent incoming
unanswered calls only. An option is provided so you may also choose to access the
most 20 recent answered calls, and the 20 most recent outgoing calls placed from
your voice/data terminal, or you may choose to turn off the Call Log. Use to check on
calls you missed (the unanswered calls) and to remind you of those calls you
answered or placed most recently.
Call Log Indicator
Set your display so you receive an indication at the top of your
display screen when a new unanswered incoming call is placed into your Call Log.
Call Progress
The API dialing Call Progress feature specifies if and when the
speaker becomes active while placing a voice call using API.

darker or lighter against the background of the screen.

know a selection has been accepted. An error beep (one beep) alerts you that you
