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.)
1

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.

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.

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 mandatory, you may still 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.
