Installing the Cable Modem Back Cover

Congratulations on Your Purchase!

Your new Toshiba DOCSIS Cable Modem will provide you with high-speed access to the Internet

through your cable TV (CATV) network-accesses at a fraction of the time it takes traditional

telephone modems. In addition, your service will be always connected. Those two features give you

the information you want, when you want it …and your telephone line is kept free.

Important Rules for Safe Operation

In addition to the careful attention devoted to quality standards in the manufacture of

your Toshiba DOCSIS Cable Modem, safety is a major factor in the design of every

product. However, safety is your responsibility, too.

This section lists important information that will help assure your enjoyment and proper use of the

Cable Modem and accessory equipment. Please read them carefully before operating and using

your modem.

Installation

Read and Follow Instructions -You should read all the safety and operating

instructions before operating the modem. Follow all operating instructions.

Retain Instructions -You should save all the safety and operating instructions, for

your future reference.

Heed Warnings -Comply with all warnings on the products and in the operating

instructions.

Check Power Sources -Operate this product only from the type of power source

indicated on the product's marking label. If you are not sure of the type of power

supplied to your home, consult your dealer or local power company.

Be Careful of Overloading -Do not overload wall outlets or extension cords, as

this can result in a risk of fire or electric shock. Overloaded AC outlets, extension

cords, frayed power cords, damaged or cracked wire insulation, and broken plugs

are dangerous. They may result in a shock or fire hazard. Periodically examine the

cord, and, if its appearance indicates damage or deteriorated insulation, have it

replaced by your service technician.

Protect Power Cords -Route power supply cords so that they are not likely to be

walked on or pinched by items placed upon or against them.

Pay particular attention to cords where they are attached to plugs and

convenience receptacles, and examine the point where they exit from the product.

Check Ventilation -Slots and openings in the enclosure are provided for

ventilation to ensure reliable operation of the product and to protect it from

overheating. Do not block or cover these openings. Never block these openings by

placing the product on a bed, sofa, rug, or other similar surface. Never place this

product near or over a radiator or heat register, or any other heat source (including

amplifiers). Do not place this product in a built-in installation, such as a bookcase

or equipment rack, unless you provide proper ventilation.

Do Not Use Accessories -Do not use attachments, unless they are

recommended by Toshiba, as they may cause electrical or fire hazards.

Use the Recommended AC Adapter -You must use the Adaptor that comes with

your Toshiba Cable Modem.

Do Not Use Near Water -Do not use this product near water-for example, near a

bath tub, sink or laundry tub, in a wet basement or near a swimming pool, and the

like.

Do Not Place Near High Temperature Source -for example near a steamer,

Kitchen range fire, and the like.

Use Caution in Mounting This Product -Do not place this product on an

unstable surface or support. The product may fall, causing serious injury to a child

or adult, as well as serious damage to the product.

Use Care in Moving Product-and-Cart Combinations -Quick stops, excessive,

force and uneven surfaces may cause the product-and-cart combination to

overturn.

Ground the Cable System -Be sure that the outside cable system is grounded,

so as to provide some protection against voltage surges and built-up static

charges.

Section 810 of the National Electric Code, ANSI/NFPA No. 70-1984 (Section 54 of

the Canadian Electrical Code, Part 1) provides information with respect to proper

grounding of the cable system.

Do not disconnect RF cable from your Cable Modem while the power to your

modem is on.

Use

Unplug Power Before Cleaning -Do not use liquid cleaner or aerosol cleaner.

Use a damp cloth for cleaning.

Keep Objects Out of Openings-Never push objects of any kind into this product

through openings, as they may touch dangerous voltage or "short-out" parts, which

could result in a fire or electric shock. Never spill liquid on the product.

Protect From Lightning-For added protection for this product during a lightning

storm, or when it is left unattended and unused for long periods of time, unplug it

from the wall outlet, and disconnect the cable system. This will prevent damage to

the product due to lightning and power line surges.

Take at least 10 seconds betweenAC plug off and on.

Service

Do Not Remove Covers -Do not attempt to service this product yourself, as

opening or removing covers may expose you to dangerous voltage or other

hazards. Refer all servicing to qualified service personnel.

Unplug this product from the wall outlet carefully, as the AC adapter may be hot.

Refer Servicing to Qualified Service Personnel Under the Conditions Listed Below

♦When the power supply cord or plug is damaged.

♦If liquid has been spilled or objects have fallen into the product.

♦If the product has been exposed to rain or water.

♦If the product does not operate normally by following the operating

instructions.

♦If the product has been dropped or the cabinet has been

damaged.

♦When the product exhibits a distinct change in performance,

such as the inability to perform basic functions -this

indicates a need for service.

Require Safety Check -Upon completion of any service or repairs to this product,

ask the service technician to perform safety checks recommended by service point

to determine that the product is in safe operating condition.

Overview

The modem provides you with high-speed data communications over the television

cable network by following the widely accepted DOCSIS/MCNS standards being

developed by the Multimedia Cable Network System (MCNS) consortium. Those

standards offer a combination of high performance and interoperability among

many of the cable system operators in North America.

How does a cable modem work?

As you know, high and low electrical voltage levels represent digital signals. And

how fast these levels can switch and still be transmitted is determined by the

"bandwidth" of the transmission system. The pair of wires used in a telephone

connection hasgreatly limited bandwidth, because of their electrical characteristics.

So what we do is connect a device called a modem between the computer output

and the phone line. The modem generates an electrical wave whose strength and

phase change in step with the highs and lows of the computer's digital output. It's

because of the "smoothness" of the resultant signal that a higher data rate can be

transmitted.

A cable modem MOdulates and DEModulates electrical signals in the same sense

that the telephone modem does. However, since coaxial cable can carry much

higher wave frequencies, cable modems are far more sophisticated. Their internals

can include a tuner, a bridge, an encryption/decryption device, an SNMP agent, an

Ethernet hub and USB interface. Furthermore, none of the activity caused by

these circuits and codes disturbs your regular cable TV reception.

How does a cable modem connect to a computer?

The 10BASE-T Ethernet connection and USB connection used in this Cable

Modem

are emerging as the most popular means of connecting a cable modem.

The new DOCSIS standard may change this in the future. But for now, a

10BASE-TEthernet or USB must be ready in your computer for the Cable Modem

to work.

What is DOCSIS?

Data Over Cable Service Interface Specifications. DOCSIS defines interface

requirements for cable modems involved in high-speed data distribution over a

cable television network. On November 17, 1997, Cable Television Laboratories,

Inc. (Cable Labs) and its members established a formal path of certification for

cable modem equipment suppliers to obtain an interoperability seal for their

products based on the DOCSIS specification. This certification process provides

cable modem equipment suppliers with a fast, market-oriented method for

attaining cable industry acknowledgment of compliance with DOCSIS.

The seal is meant to provide the purchaser with a way to be confident that the

modem equipment to be purchased is compliant with the specification, and that the

equipment interoperates with DOCSIS products made by other vendors.
