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.

●

Fixed (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.

●

Display 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 ( 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).

and the 7-line

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/data terminal. Check with your system manager to see which of these features you can use.

Fixed (Button) Features

Conference

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.

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.

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/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.

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

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/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 Log

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.
