About This Guide
Purpose
The system described in this guide consists of premises equipment and Centrex
services. Although the terms “premises equipment,” “Centrex services,” and
“system” have broader meanings elsewhere, this guide uses those terms to
refer specifically to the following definitions:
Premises equipment refers to the AT&T equipment controller and MLS- ■
and MLC-model telephones that you purchased as part of your Partner®
II Centrex Communications System, plus all other telecommunications
devices connected to your equipment controller. This equipment is
installed at your place of business.
■ Centrex services include the Centrex lines that are connected to the
equipment controller and the features available on those Centrex lines.
These services (which may be offered in your area under a different name
such as ESSX,® CENTRON,® or Plexar®) must be arranged for
separately with your local telephone company.
■
System refers to the combination of premises equipment and Centrex
services described above.
The main purpose of this guide is to provide instructions for installing,
programming, and using your premises equipment. Because the selection of
services available from the local phone companies continually expands and
changes—to keep pace with the needs of businesses and with technological
advances in the world of communications—this guide does not provide detailed
information about Centrex services. For specific information about your Centrex
services, see the Centrex documentation provided by your local telephone
company.

Terminology
The following terms are used throughout this guide, and are important for
understanding how your system works. In addition, each chapter in this guide
begins with a “Terminology” section that defines key terms used in the chapter.
All terms are also defined in the Glossary.

System
Telephone services that your local telephone company
provides from a Central Office (CO) located outside your
business premises, including Centrex lines connected to the
equipment controller and the features available on those
Centrex lines. (Your telephone company may call Centrex by
another name.)
The total block of Centrex lines you subscribe to—all or some
of which may be connected to the equipment controller for
your system—together with the Centrex services associated
with those lines. See also Premises equipment and System.
The AT&T product that you purchased as part of your
system. This product consists of a group of modules that
connect Centrex lines coming into your building to the
extensions in your system. The equipment controller also
provides equipment features.
A feature provided by your equipment controller (as opposed
to a service provided by Centrex).
The AT&T telephones that you purchased as part of your
system. These telephones are specifically designed for use
with the equipment controller. Models include the MLS-34D™
telephone, MLS-12D™ telephone, MLS-12™ telephone,
MLS-6™ telephone, and MLC-6™ telephone.
The AT&T equipment controller and the MLS- and
MLC-model telephones that you purchased as part of your
system, plus all other telecommunication devices that are
connected to your equipment controller. For purposes of this
guide, premises equipment does not include any equipment
that connects directly to Centrex lines without going through
the equipment controller. See also System and Centrex
system.
An industry-standard touch-tone or rotary phone such as you
might have in your home. Some standard phones include
special feature buttons for frequently-used calling functions.
Your premises equipment, in combination with the Centrex
lines that are connected to your equipment controller and the
Centrex services that are available on those lines. See also
Centrex system and Premises equipment.
vi About This Guide

How to Use This Guide
This guide provides instructions and advice on the following topics:
■
■
Installation. If you are installing the system for the first time, read
Chapters 1 and 2 and Appendix D, which provide an overview of the
system, instructions for equipment installation, and equipment
specifications.
If your company already has modular jacks for all outside lines and
extensions, you may be able to use the existing wiring to install the
equipment controller and connect telephones yourself (see Chapter 2).
If you prefer to have an AT&T service technician install and customize
your premises equipment, call 1 800 247-7000 (in the U.S. only) or
your AT&T authorized dealer.
Your system can include a wide variety of auxiliary equipment,
including fax machines, modems, answering machines, credit card
scanners, and call reporting (SMDR) devices. See Chapter 7 for
advice on setting up these industry-standard devices to work
effectively with your system.
Setup Decisions. If you are a new user, read Chapters 1, 3, 4, and 6, to
familiarize yourself with the features provided by your equipment
controller, to learn how to program the equipment controller and
individual phones, and to learn how to handle calls.
Chapter 3 explains how your equipment controller complements
Centrex services, providing a variety of features that support Centrex
capabilities and making it easy for you to access Centrex features.
Chapter 4 helps you make decisions about customizing the premises
equipment, to use additional features and capabilities provided by
your equipment. Chapter 6 provides call-handling instructions for
standard phones and for MLS- or MLC-model phones.
Programming. Chapter 5 gives step-by-step instructions for all of the
programming procedures for your premises equipment. You can use the
information in this chapter as a reference, to help you carry out your
decisions about customizing your premises equipment.
Making Changes. If you need to reprogram the premises equipment or
individual extensions, see Chapter 5, “Programming Reference,” or the
Programming Quick Reference pages at the back of this book.
If you are adding equipment to your system, see Chapter 2, “Installing
the Equipment,” Chapter 5, “Programming Reference,” and Chapter 7,
“Using Auxiliary Equipment.”
Training Co-Workers. Chapter 6 explains how to handle calls and use
equipment features effectively. To help users get the most out of their
phones, give each telephone user a Quick Reference card and filled-in
copies of the “Speed Dial Numbers” form in the System Planner or
Appendix A of this book.

About This Guide vii

Before training co-workers, read Appendix B to decide whether to
make intercom calling features available to telephone users. (These
equipment features require that users know the jack numbers where
lines and extensions are connected to the equipment controller.) In
addition, panels 6 and 7 of the Quick Reference card present intercom
calling features.
Solving Problems. Appendix C provides information on solving
problems and ordering additional accessories and equipment. If your
premises equipment malfunctions, you may be able to solve the problem
by following the steps provided in “Troubleshooting,” starting on page
C-3.
Daily Operation. Depending on how your system is set up, you may
■
■
need to oversee some of the system’s daily operations. For example, if
you use the Night Service feature available with your equipment
controller, you will need to turn on Night Service at the end of each day
before leaving the office. (See “Using Night Service” on page 6-18.)
Once you are experienced with the system, use the Table of Contents or Index
to locate the information you need.
Product Safety Labels
This book contains several product safety statements, identified by a
CAUTION:
Indicates the presence of a hazard that will or can cause minor personal
injury or property damage if the hazard is not avoided.
WARNING:
Indicates the presence of a hazard that can cause severe or fatal
personal injury if the hazard is not avoided.
Carefully read the
WARNING statement on page 2-9. Opening the
equipment modules or backplane will expose you to hazardous voltages, which
can cause severe personal injury or death. Also, read “Important Safety
Instructions” on page 2-ii before performing any installation procedures.
Reference Materials
The following reference materials are available to help you install, program, and
use the premises equipment. To order them, call the AT&T Customer
