3D Connexion 555-540-702 manual Introduction, Features

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.)
