Introduction

This guide describes the features available to you from AT&T

System 25 through a new series of multifeature single-line voice

terminals. It also provides instructions for using those features.

For your convenience, the features are arranged in alphabetical

order.

Your voice terminal is ready to use as soon as it’s connected to

System 25. So as you learn to use the features, you can make

and receive calls with your voice terminal just as you would with

an ordinary telephone. The instructions in the owner’s manual

that came in the box with the set explain how to assemble your

voice terminal and connect it to the system. The manual also

includes certain reference information you may want to review at

a future time.

Features

Your AT&T System 25 has two types of features, fixed and

assignable, that transform your telephone into a voice terminal.

Fixed features are available on every single-line voice terminal.

Assignable features are assigned by your System Administrator.

In this guide, fixed features are identified by a check in the box

at the top of the page.

Buttons

A multifeature single-line terminal can have two kinds of

buttons: fixed buttons and memory buttons. While all voice

terminals in this series have fixed buttons, some models don’t

have memory buttons. If your voice terminal doesn’t have

memory buttons, you can disregard references to memory

buttons in this guide.

Fixed Buttons

The fixed buttons are the permanently labeled buttons on the

voice terminal. On the 420 Speakerphone, shown in Figure 1,

they are the six buttons directly above the dial pad. If you have

a different voice terminal, they may be located elsewhere. In

this guide, fixed buttons have a blue background with white

letters, as in the following list.

Your voice terminal may not have all six fixed buttons. If, for

example, your voice terminal doesn’t have memory buttons,

then it won’t have the fixed button

Memory Buttons

The 12 buttons appearing directly above the fixed buttons on the

420 Speakerphone are programmable memory buttons. You can

use these buttons (shown hand-labeled in Figure 1) to store

frequently dialed numbers. To learn how to save numbers in

memory buttons, see the heading Programming Memory Buttons in

this guide. When you save numbers in memory buttons, make

sure that you label the buttons appropriately. Figure 2 shows

how to remove the plastic cover from the label card on the

420 Speakerphone using your thumb and forefinger to press up

from the bottom and down from the top.

You should use a pencil to label the buttons so that you can

Note

The three top buttons in the

new ones in the event that you

left column of memory buttons on

the 420 Speakerphone (identified as Emergency Number

Locations in Figure 1) are marked for fire, police, and medical

emergency numbers. The symbols are a reminder that you

should consider emergency numbers when choosing numbers to

program into memory buttons. If you decide not to program

emergency numbers into these buttons, cover the symbols with a

piece of tape so that nobody will be misled by them in the event

of an emergency. AT&T assumes no responsibility for customer

reliance on these markings.

Dial Signals

The 420 Speakerphone has a dial switch on the underside of the

phone, as shown in Figure 3. Use this switch to set the phone

for either tone or pulse (rotary) dialing. Since System 25

programming and feature access codes require tone dialing, it is

strongly recommended that you set the dial switch to TONE (right).

When your System 25 was installed, you were assigned a

Personal Dial Code (PDC). In most cases, your PDC is your

extension number. If a voice terminal is shared, each person

may have been assigned their own “floating” PDC.

For Additional Information

See your System Administrator if you have any questions or

would like additional information about your System 25 features.

Account Codes

For bookkeeping purposes, your System Administrator may

assign account codes to use with certain calls. You will be

disconnected from your call when you dial the feature access

code (* 0), so do not dial it until you have finished your conversation.

Follow these steps to enter an account code.

1 Before you hang up, press

2 Listen for confirmation tone and dial tone.

4 Dial the account code or the speed dialing

code that is associated with the account code.

5 Listen for confirmation tone and then

hang up.

Note

You can program the feature access code (*0) or

an account code into a memory button. You can

also program both the feature access code and an

account code (up to 13 digits) into a memory

button. If you program one or more memory

buttons for this feature, label them appropriately.
