Single-Line Telephone User Guide  
Prepared by the  
Technical Publications Group  
 
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  
A fixed feature is one that is provided on every  
assignable.  
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.)

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.

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

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.

any, for which you must enter an account code.

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 (a  
“queue” ) for the extension or line to become available. The  
system will then ring you back and complete the call.  
For inside calls, use Callback when you hear a busy or special  
ringback tone. For outside calls, use Callback only when you  
hear a fast busy tone. (You may hear the callback request

Programming Speed Dialing Codes  
You can program telephone numbers, account codes, and  
System Speed Dialing codes into your Personal Speed Dialing  
codes. System 25 allows you to program strings of numbers and  
special characters (maximum of 25 characters) into the dialing  
codes.  
The first part of this entry describes, with examples, how to use  
special characters when programming. The remaining part of  
this entry describes how to actually program or remove Personal  
Speed Dialing codes.  
Special Characters  
You may need to use the “*”  
and the “ #” when you program

to-end signaling, at the beginning of a Speed Dialing code, or as  
an actual character.  
Using * as a Pause  
A "*" by itself will produce a 1.5 second pause. For example,  
you may want to program a pause between the outside line  
access code and the telephone number.  
You program: 9*5557023

Speed Dialing  
Speed dialing allows you to dial telephone numbers (or account  
“ #” and a 2- or 3-digit code. There are  
codes) by simply dialing  
two kinds of speed dialing: Personal and System.  
Personal Speed Dialing codes are 2-digit numbers that allow you  
to program up to twenty personal numbers. These Personal  
Speed Dialing codes use the numbers #20 through #39.  
System Speed Dialing codes are programmed by your System  
Administrator, and are used for numbers that are frequently  
called by people in your company. System Speed Dialing codes  
use the numbers # 100 through # 189.
