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.
4
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.
5
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.
