Introduction

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

System 25 through a single-line 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 an ordinary phone.

System 25 supports both touch-tone and rotary sets. However,

if you have a rotary set, you will not be able to use the features

that require you to enter a “*” or “ #” character.

Features

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

assignable.

A fixed feature is one that is provided on every

single-line telephone. (In this guide, fixed features are indicated

at the beginning of a feature description by a box with a check.)

An assignable feature is not provided automatically. 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 Switchhook

The switchhook is the button held down by the handset when it

rests in the cradle on your telephone. Some System 25 features

require that you use the switchhook to signal the system.

When you are instructed to press the switchhook, press the

button down as far as it will go for approximately 1/2 second and

then release it. If the switchhook is released too soon, the signal

will not work. If you hold the switchhook down for too long

your call will be disconnected.

If you want to hang up and place another call right away, be

sure to hold down the switchhook for more than two seconds.

NOTE: If you have a RECALL or FLASH button on your

telephone, you can press it instead of the switchhook.

The RECALL or FLASH buttons cannot be used to disconnect a

call.

Ringing Tones

System 25 signals you with three distinctive rings. The rings

and their descriptions are listed below.

INSIDE CALL IIIIIIIIIIIIIIIIIIII (one long ring)

Your call is from a person inside your company.

OUTSIDE CALL IIIII IIIII (two short rings)

Your call is from the attendant or someone outside your

company.

PRIORITY RING IIIII IIIII IIIIIIIIII (two short rings and one long ring)

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.

Handset Tones

System 25 signals you with tones that are heard through the

handset. The tones and their descriptions are listed below.

DEQUEUEING TONE II II II (three short tones)

Data Dial Code (DDC)

When your System 25 was installed, Data Dial Codes (DDCSs)

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).

Additional Information

See your System Administrator if you have any questions or

would like additional information about your System 25 features.

Code Entry feature.

any, for which you must enter an account code.
