Security of Your System Preventing Toll Fraud

As a customer of a new telephone system, you should be aware that there exists an increasing problem of telephone toll fraud. Telephone toll fraud can occur in many forms, despite the numerous efforts of telephone companies and telephone equipment manufacturers to control it. For important information regarding your system and toll fraud, see Appendix A, “Customer Support Information.” It follows Maintenance and Trobleshooting in this binder.

Federal Communications Commission Statement

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his own expense. For further FCC information, see Appendix A, “Customer Support Information.” It follows Maintenance and Troubleshooting in this binder.

Safety

The exclamation point in an equilateral triangle is intended to alert the user to the

presence of important operating and

maintenance (servicing) instructions in the

literature accompanying the product.

IMPORTANT SAFETY INSTRUCTIONS

When installing telephone equipment, always follow basic safety precautions to reduce the risk of fire, electrical shock, and injury to persons, including:

Read and understand all instructions. Follow all warnings and instructions marked on or packed with the

product. Never install telephone wiring during a lightning storm. Never install a telephone jack in a wet location unless the jack is

specifically designed for wet locations. Never touch uninsulated telephone wires or terminals unless the

telephone wiring has been disconnected at the network interface. Use caution when installing or modifying telephone lines. Use only AT&T-manufactured MERLIN LEGEND Communications

System circuit modules, carrier assemblies, and power units in the MERLIN LEGEND Communications System control unit.

Use only AT&T-recommended/approved MERLIN LEGEND

Communications System accessories.

If equipment connected to the analog extension modules (008, 408,

408 GS/LS) or to the MLX telephone modules (008 MLX, 408 GS/LS-

MLX) is to be used for in-range out-of-building (IROB) applications, IROB protectors are required.

Installation xv

Safety

Do not install this product near water, for example, in a wet basement location.

Do not overload wall outlets, as this can result in the risk of fire or electrical shock.

The MERLIN LEGEND Communications System is equipped with a 3-wire grounding-type plug with a third (grounding) pin. This plug will fit only into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact an electrician to replace the obsolete outlet. Do not defeat the safety purpose of the

grounding plug.

The MERLIN LEGEND Communications System requires a

supplementary ground. Do not attach the power supply cord to building surfaces. Do not

allow anything to rest on the power cord. Do not locate this product

where the cord will be abused by persons walking on it.

Slots and openings in the module housings are provided for ventilation. To protect this equipment from overheating, do not block these openings.

Never push objects of any kind into this product through module

openings or expansion slots, as they may touch dangerous voltage

points or short out parts, which could result in a risk of fire or electrical

shock. Never spill liquid of any kind on this product.

Unplug the product from the wall outlet before cleaning. Use a damp

cloth for cleaning. Do not use cleaners or aerosol cleaners. Auxiliary equipment includes answering machines, alerts, modems,

and fax machines. To connect one of these devices, you must first

have a Multi-Function Module (MFM).

Do not operate telephones if chemical gas leakage is suspected in the area. Use telephones located in some other safe area to report the trouble.

xvi

Installation

Safety

WARNING:

For your personal safety, DO NOT install an MFM yourself. ONLY an authorized technician or dealer representative shall install,

set options, or repair an MFM.

To eliminate the risk of personal injury due to electrical shock, DO

NOT attempt to install or remove an MFM from your MLX telephone.

Opening or removing the module cover of your telephone may expose

you to dangerous voltages.

About This Book

The MERLIN LEGEND Communications System is an advanced digital switching system that integrates voice and data communications features. Voice features include traditional telephone features, such as Transfer and

Hold, and advanced features, such as Group Coverage and Park. Data

features allow both voice and data to be transmitted over the same system

wiring.

Intended Audience

This book is intended for qualified field technicians who install and upgrade the system.

How to Use This Book

Qualified technicians can use this book as a guide to installation and upgrading procedures. The technician is given specific steps for installing all units of the control unit, telephones, adjuncts and data equipment.

Terms and Conventions Used

In this document, the terms in the following list are used in preference to

other, equally acceptable terms for describing communications systems.

Lines, Trunks and Facilities

Facility is a general term that designates a communications path between a

telephone system and the telephone company central office. Technically a

trunk connects a switch to a switch, for example the Communications System to the central office. Technically, a line is a loopstart facility or a communications path that does not connect two switches (for example, an intercom line or a Centrex line). However, in actual usage,

the terms line and trunk are often applied interchangeably. In this book, we

use line/trunk and lines/trunks to refer to facilities in general. Specifically, we refer to digital facilities. We also use terms such as personal line, ground-

start trunk, Direct Inward Dialing (DID) trunk, and so on. When you talk to your local telephone company central office, ask them what terms they use for the specific facilities they connect to your system.

■ Installing optional equipment

This chapter provides an overview of the installation process, which varies from customer to customer.

Installation Sequence

The following is a list of the components that the system can include and shows the order in which you should install them. When installing your customer’s system, try to adhere to this order as much as possible:

1. Install the control unit (required).

2. Connect power accessories to the control unit (optional).

3. Install the telephones (required) and adjuncts (optional).

4. Connect the telephones to the control unit (required).

Introduction 1-1

System Forms

Connect the control unit to the network interface (required).

5. Connect the channel service unit (CSU) to the 100D module on the

6. control unit (required only with the 100D module).

Connect the printer and PC to the control unit (optional). Connect data equipment to the control unit (optional).

9. Install the control unit housing (required).

10. Install applications (optional).

11.

A list of required tools and equipment is given before each installation

procedure.

System Forms

Some of the installation procedures in this guide refer to system forms. These

forms indicate information that is specific to your customer’s system. The

forms you need should be included with the system programming disk or

memory card, which contains all of the programming specifically for your

customer’s system.

If you are upgrading an existing system and do not have the required forms

for your customer’s system, you can load System Programming and

Maintenance (SPM) and print out the required forms.

If you find that you do not have a completed set of system forms for your customer’s system, contact your technical support organization or the Customer Service Center (CSC). See the inside front cover for telephone

numbers. The system forms that you need are specific for each system, and include

some or all of those described in the following sections.
