Glossary
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.)

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.

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

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.

If you are required to use account codes for outgoing calls, the account code must be entered before you can place an outgoing call.
