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 (

[ 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).

●

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 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.

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.

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/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 The 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.

Contrast Change the contrast level of your display so the letters or numbers are darker or lighter against the background of the screen.

Data Place a data call and set up Data Options.

6

Data Indicator Set your display so you receive confirmation whenever an active data call is in progress.

Directory Used to create, view, edit, or call entries in your personal directory. This directory can include up to 144 extensions or outside numbers and the names of the associated party. Once your Directory is set up, you can delete entries and search for entries already entered. Numbers in your Directory can be arranged in alphabetical order, in user-defined groups, or both. Use [ Dir ] to quickly dial a call.

Use your Directory 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 is dialed.

Exit button Exits a softkey feature and returns the voice/data terminal display to your Home Screen. The top two lines again show you the time and date and any relevant system information.

Home Screen

Select a display screen that will appear each time you press [ Exit ] .

In this way, you can quickly access a screen you use often.

Lock Allows you to lock your Directory changes so no one else can edit or delete them; lock your Call Log so no one else can view your Call Log entries; lock all of the softkeys so no one else can view or change any of the features accessed by the softkeys.

Screen The Screen features include Display Rate and Message Type.

Display Rate Allows you to set the length of time the display message remains on the screen. There are three rates: Slow, Medium, and Fast.

Message Type Allows you to select the type of messages you want to see on the screen: either error messages only or both error and information timed messages.

Number of Names (on a Directory Page) Allows you to view either 10 names or nine names + Quit on an individual Directory page. If you choose to have 10 names on the Directory screen at one time, you can leave the Directory only by pressing

[

Exit

] or [

Menu

] (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/data terminal’s ring from that of other nearby voice terminals.

Self-Test Performs a diagnostic test of your voice/data terminal including the lights, ringer, buttons, and display. Note: When you perform a self-test of the voice/data 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 Clock For setting the date and time on your voice/data terminal display.

Set Speakerphone When you set the built-in speakerphone, it performs a test of the surrounding environment and adjusts itself for optimal performance.

Tones A confirmation tone (sequential low and high tones) is provided to let you know a selection has been accepted. An error beep (one beep) alerts you that you have pressed an invalid softkey. An error tone indicates you have made a mistake in your softkey entry. You may choose to turn the confirmation tone and the error beep 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 telephone number, an extension number, or a trunk or feature code. There are four possible types of lists—personal, group, system, and enhanced—and you can have a total of three out of the four 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: This feature 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/data 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/data 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/data 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.

How to Use the Switch Features

Since your 8520T voice/data terminal is connected to a DEFINITY Communications

System Generic 1 or Generic 3, you may be able to use some of the features listed in this section. Check with your system manager to see which of these features have been assigned to your voice/data terminal.

You can activate or cancel most of the features by dialing unique 2- or 3-digit codes for that feature. Ask your system manager for the feature codes for your system. Then, in the blanks provided within the procedures, write in the assigned feature code numbers.

In most cases, before you begin a procedure, you must have the handset off-hook (removed from the cradle of the voice/data terminal).
