Glossary

Introduction

This guide describes the features available to you from AT&T
System 25 through a multiline telephone and provides
instructions for using the features. For your convenience, the
features are arranged in alphabetical order.

Your telephone is ready to use as soon as it is connected to the
System 25. Therefore, as you learn to use the features, you can
make and receive calls with your telephone just as you would
with any ordinary phone.

Features

Your AT&T System 25 has two types of features: fixed and
assignable.

A fixed feature is one that is provided on all
multiline telephones. (In this guide, fixed features are indicated
at the beginning of the feature description by a box with a
check. )

An assignable feature is not provided automatically on all
phones. It must be “assigned” by your System Administrator.
(In this guide, assigned features are indicated at the beginning of
a feature description by an empty box. )

fixed feature

assignable feature

Check with your System Administrator as to which features have

been assigned to you. (As a reminder, you can place a check in

the box of each assignable feature as you receive it.)

The telephones shown below and on the following page are
some of the phones that are used with System 25. You can use
this guide with any of these telephones.

NOTE: A fourth type of button can be found on the display unit,

and is represented in this way:

Each multiline telephone has System Access buttons that are
used to place and receive calls and to access special system
features. On most phones, these buttons are located on the
upper left portion of the faceplate, and are labeled with your
extension number.

Line Selection

Your telephone should automatically select a line when you lift
the handset to place a call, and automatically select a ringing
line when you lift the handset to answer a call. These options
are set by the System Administrator, and the procedures in this
guide assume that you have both of them. (If you do not have
these options, you must press the appropriate line button at the
beginning of most precedures.)

Handset Tones

System 25 signals you with tones that are heard through the
handset. The tones and their descriptions are listed below.

DIAL TONE

(a continuous steady tone)

You can dial.
CONFIRMATION TONE

(three short tones)

Your action has been accepted.

FAST BUSY TONE

The number you dialed was busy, misdialed, or restricted.

CALL WAITING TONE (short tone(s) heard during a call)

(the waiting call is an inside call)

(the waiting call is an outside call)

You have a call waiting to be answered.
QUEUEING TONE

(five short tones)

Your request for a callback has been confirmed.
DEQUEUEING TONE

(three short tones)

The extension or outside line that you requested for callback is
now available.

5

Ringing Tones

System 25 signals you with four distinctive rings. The rings and
their descriptions are listed below.

Your call is from a person inside your company.

Your call is from the attendant or someone outside your
company.

This can indicate a call on another line; a busy-to-idle reminder;
a manual signal; or that your telephone is in program mode.

You are being alerted that your request for Callback can now be
completed; or a call is being set up remotely for your phone via
a data feature known as Third-Party Call Setup.

Lights

A steady red light indicates the line you should
use when you lift the handset.

A steady green light indicates the line or feature
in use.

A slow blinking green light indicates an
incoming call.

A fast blinking green light indicates a call on
hold or a queued call. (An intermittent blinking
green light indicates a call held temporarily while
being transferred or conference.)

6

Data Dial Code (DDC)

When your System 25 was installed, Data Dial Codes (DDCs)
were assigned to data terminals. If you have a data terminal
associated with your System 25, you will receive separate
information regarding its use.

Personal Dial Code (PDC)

Personal Dial Codes (PDCs) were assigned to telephones. In
most cases, your PDC is your extension number. If a telephone
is shared by two or more people, each person may have been
assigned their own

“floating” extension number (FPDC).

Display Unit

If your telephone has an attached display, use the procedures
and sample screens under the following sections: “Directory”,

“Display”, and “Display Functions”. If your telephone does not

have a display unit, you can skip these parts of the guide.

Additional Information

See your System Administrator if you have any questions or
would like additional information about your System 25 features.

Multiline Features

Account Code Entry

For bookkeeping purposes, your System Administrator may

assign account codes to use with certain calls. If you are
required to use account codes for outgoing calls, the account
code must be entered before you can place an outgoing call. If
this feature is not mandantory, you may still optionally use the
Account Code Entry feature.

See your System Administrator to verify the types of calls, if

any, for which you must enter an account code.

Bridged Access

This feature allows for a common connection between a specific
button, on your telephone and a specific line
button,

on someone else's telephone. You can

join in a call or cover the other line by using your bridged access
button. Up to 15 people can use their bridged access buttons for
the same system access button.

Your System Administrator can set your
to ring in any of the following ways:

button

■ Ring immediately when a call rings

line.

■ Ring after a predetermined number

at the other person’s

of rings (delayed ring).

Not ring at all.

If you are on a call and another call comes in on a previously
idle

button, you will hear abbreviated ringing.

When someone picks up the call, the light next to your

button becomes steadily lit.

Bridging Onto a Call in Progress

1 Press the

button next to the steadily lit

green light.

You are connected to the call in progress.

2 To drop out, simply hang up at any time.

NOTE: You cannot bridge onto a call if any one of the

extensions on that call has their Exclusion feature turned on
or if the conference limit has already been reached for that
call.

12

Call Accountability

You can use your own extension number at any other extension

to place toll calls that should be billed to you.

Billing Calls to Your Extension

1 Listen for dial tone, then press

2 Dial your extension number.

3 Listen for dial tone, then dial the telephone number.

NOTE: If you make a mistake, hang up and restart the

sequence.

13

Call Waiting

If all of your System Access buttons are busy, you may be
notified (through your handset) that a call is waiting. If you
hear one short tone, it is an inside call waiting; two short tones
indicate you have an outside call waiting.

If you have a System Access-Outgoing

button on

your telephone, you can put your calls on hold and answer the
call waiting.

If you do not have this button, you must end one

of the existing calls in order to answer the call waiting.

Callback

If a System 25 extension or outside line is busy when you place a
call, you can request a callback. Your call will wait in a line
(called a queue) for the extension or line to become available.
The system will then alert you with a priority ring and complete
the call.

For inside calls, use Callback when you hear a busy tone or a
special ringback tone.

For outside calls, use Callback only when

you hear fast busy tone.

NOTE: You may hear the callback request queueing tone

automatically when you place certain calls.

lines.

who added you to the conference, you will also drop anyone
added to the conference by that person.

2 Press the button of the person you want to drop.

The light associated with the dropped call goes off.

Coverage

If your System Administrator has administered this feature, calls
to you can be answered (covered) at specified telephones when
you do not answer the call yourself. Calls unanswered at your
telephone will start ringing at the covering telephone after a
preset number of rings.

However, if you are busy on another

line, calls will go to coverage after a preset number of rings

(usually one).

Buttons used for Coverage answering are:

Coverage calls for one specific person are sent

to an Individual Coverage button assigned to the extension.

Coverage calls for a group of two or more

extensions come in on a Group Coverage button associated
with the group the extensions are assigned to.
