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.

Special Instructions

Before you use the procedures for the first time, read the general directions below for
using the many features of DEFINITY Generic 1 and Generic 3. Your system
manager can supply the information required.

●

●

●

To the right of each feature name is a box. Check with your system manager to
see which features you can use at your voice/data terminal. For each feature
that you have, mark a

[ ✔ ]

in the blank box as a reminder.

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).

●

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 procedural step or have made a dialing error. Hang up, get dial
tone, and begin again at Step 1.

Conventions Used in This Section

The following conventions are used in the procedures in this section:
