Introduction

This guide describes the features available to you from AT&T System 25 through a multiline 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 any ordinary phone.

Features

Your AT&T System 25 has two types of features: fixed and assignable. multiline telephones. (In this guide, fixed features are indicated at the beginning of the feature description by a box with a check. )

A fixed feature is one that is provided on all

An assignable feature is not provided automatically on all phones. 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. )

features. On most phones, these buttons are located on the upper left portion of the faceplate, and are labeled with your extension number.

Line Selection

Your telephone should automatically select a line when you lift the handset to place a call, and automatically select a ringing line when you lift the handset to answer a call. These options are set by the System Administrator, and the procedures in this guide assume that you have both of them. (If you do not have these options, you must press the appropriate line button at the beginning of most precedures.)

handset. The tones and their descriptions are listed below. DIAL TONE

Ringing Tones

System 25 signals you with four distinctive rings. The rings and

their descriptions are listed below.

Your call is from a person inside your company.

Your call is from the attendant or someone outside your

company.

This can indicate a call on another line; a busy-to-idle reminder;

a manual signal; or that your telephone is in program mode.

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.

Lights

A steady red light indicates the line you should use when you lift the handset.

A steady green light indicates the line or feature

in use.

A slow blinking green light indicates an incoming call.

A fast blinking green light indicates a call on hold or a queued call. (An intermittent blinking green light indicates a call held temporarily while being transferred or conference.)

Data Dial Code (DDC)

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

Display Unit

If your telephone has an attached display, use the procedures and sample screens under the following sections: “Directory”,

“Display”, and “Display Functions”. If your telephone does not

have a display unit, you can skip these parts of the guide.

Additional Information

See your System Administrator if you have any questions or

would like additional information about your System 25 features.
