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, digital signals are represented by high and low electrical voltage levels. 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 have greatly 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, a router, an encryption/decryption
device, an SNMP agent and an Ethernet hub. 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 10BaseT Ethernet connection used by TurboComm is emerging as the most popular. This
connection has been used for years to allow business computers to talk to each other in a LAN (Local
Area Network).
The new DOCSIS standard may change this in the future. But for now, an Ethernet card must be
installed in your computer for the TurboComm 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.

Consumer Cable Modem FAQ's
What is a MCNS compliant cable modem?
- A cable modem is a device that hooks up to your computer and instead of getting an internet
connection through your telephone wire (or another system), you get a connection through your cable
network (same place your cable TV connection comes from). The bandwidth is much bigger in your
cable network and allows you to get information from the internet at much faster speeds. And do not
worry, installation is done by your cable operator or computer store.
How can I as a consumer get an DAZ8801F / ECM100 Cable Modem and sign up for the high-
speed cable modem service?
-TurboComm currently sells their DAZ8801F / ECM100 Cable Modems directly to cable operators.
They in turn supply them to you. They either lease the cable modem in their monthly high-speed
data service fee or give you the option to purchase the modem. Please contact your local cable
operator to see if they offer the service in your area and reference our list of commercially
deployed areas.
What equipment do I need to use an DAZ8801F / ECM100 Cable Modem?
- A cable operator that provides the high-speed data service
- A Computer (our DAZ8801F / ECM100 Cable Modem is platform independent so it does not matter
what kind)
- A standard 10BaseT Ethernet connection (installed by your cable operator)
Can I still watch cable TV while using my DAZ8801F / ECM100 Cable Modem?
-Yes, you cable wire is split at your home so both may be used at the same time.
Can I have cable modem service but not subscribe to cable TV?
- Yes, you may have one, or both.
How much faster is an DAZ8801F / ECM100 Cable Modem connection than other internet
connections.
- Please refer to How Fast?
How long does it take to log on?
- Your DAZ8801F / ECM100 Cable Modem is always on, a connection is always open, so you never

If I call my cable operator and they say they do not offer high-speed cable modem service, what
can I do?
- Tell them that your are interested in receiving the service and fill out our lead generator found on our
web site to make them aware of the demand.
If my cable operator offers the service, but not with the TurboComm DAZ8801F / ECM100
Cable Modem, can I purchase the modem from you and use it with their service?
- Unfortunately, the cable operator decides who their cable modem vendor is going to be and you have
to go along with their decision. However, we do make up 75% of the market today so you have a good
chance of being able to use a DAZ8801F / ECM100 Cable Modem!
Can I get an internal Cable Modem?
- Yes, we are providing also PCI bus interface internal cable modem.
