5 FREQUENTLY ASKED QUESTIONS 
Here are answers to questions our customers frequently ask: 
 
Q
 What is high-speed cable Internet access
A
 Cable Internet access uses cable television wires instead of telephone lines to 
connect to the Internet. It is extremely fast and affordable and does not tie up 
telephone lines for incoming or outgoing calls and faxes. 
 
Q
 How fast is a cable modem connection? 
A
 A DOCSIS 3.0 cable modem offers Internet access at speeds up to four times 
faster than traditional cable modem services and hundreds times faster than a 
traditional telephone modem. Depending on the service offering you have 
subscribed to, you can experience speeds of over 100 Mbps. Network conditions 
such as traffic volume and the speed of the sites you visit can affect download 
speeds. 
 
Q
 Can I still watch cable TV while using my cable modem? 
A
 Yes, your cable TV line can carry the TV signal while you send and receive 
information on the Internet. 
 
Q
 What are CableLabs Certified, DOCSIS and Euro-DOCSIS? 
A
 CableLabs
®
 Certified, DOCSIS, and Euro-DOCSIS are the industry standards for 
high-speed data distribution over cable television system networks. They are 
intended to ensure that all compliant cable modems interface with all compliant 
cable systems. Your Motorola SB6120 cable modem is DOCSIS 3.0 certified and 
Euro-DOCSIS 3.0-based. 
 
Q
 What is DOCSIS 3.0? 
A
 DOCSIS 3.0 (Data Over Cable System Interface Specification) is the new standard 
for communication in Cable Networks. Your Internet access via your Cable Network 
uses channels, much like the TV channels you watch, for data transport. Your DOCSIS 
3.0 SB6120 Cable Modem sends and receives information in both directions on 
these data channels. Using the newest technology, a cable provider can link multiple 
channels together (channel bonding) to greatly increase data transfer rates to and 
from your computer using the SB6120 through the Cable Network. The SB6120 
operates in either a single-channel mode, or the higher speed 'bonded' mode. Cable 
Operators have started offering DOCSIS 3.0 service in a number of Cable Systems. 
Please contact your Internet Service Provider for ultra-broadband (DOCSIS 3.0) 
availability.
