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.
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.

RINGBACK TONE IIIIIIIIIIIIIII IIIIIIIIIIIIIII (repeating on/off tone) The number you dialed is ringing.
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).
Single-Line 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.

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 queueing tone automatically when you place certain calls.
Conference Calls You can set up a three-party conference that includes other System 25 people as well as outside callers. When you are on a conference call, if you drop the first person you placed in the conference, you will loose the entire call.

Although Following and Forwarding send your calls to another telephone, the two features differ slightly.
Forwarding You can have your personal calls sent to another extension or to an outside number. Unlike the Following feature, you do not need to be at the other telephone. Instead, simply forward your calls to another location while you are still at your own telephone. Read the information and procedures for both the Forwarding and Following features.
