Introduction - AT&T SYSTEM 25 User Manual

Introduction

This guide describes the features available to you from AT&T
System 25 through a new series of multifeature single-line voice
terminals. It also provides instructions for using those features.
For your convenience, the features are arranged in alphabetical
order.
Your voice terminal is ready to use as soon as it's connected to
System 25. So as you learn to use the features, you can make
and receive calls with your voice terminal just as you would with
an ordinary telephone. The instructions in the owner's manual
that came in the box with the set explain how to assemble your
voice terminal and connect it to the system. The manual also
includes certain reference information you may want to review at
a future time.
Features
Your AT&T System 25 has two types of features, fixed and
assignable, that transform your telephone into a voice terminal.
Fixed features are available on every single-line voice terminal.
Assignable features are assigned by your System Administrator.
In this guide, fixed features are identified by a check in the box
at the top of the page.
