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,  
USB port 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 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-T  
Ethernet 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.
