1. Before You Begin
Your new cable modem provides high-speed access to the Internet by an active Internet Connection
through your cable service provider. This user guide describes how to set up and use the cable modem.
Before installing the cable modem, you should read this user guide to ensure proper cable modem
operation.
Understand the Cable Modem’s Features
Your cable modem has the following features to help you access and use the Internet:
• Two-way design allows the cable modem to send and receive data over the cable television
network.
• Cable bandwidth allows data rates of up to 38 megabits per second (Mbps)*, which is faster
than analog modems, integrated services digital network (ISDN), or asymmetric digital
subscriber line (ADSL).
• Using your cable line means that the cable modem is always on, always connected, and does
not tie up your phone line.
• Plug-and-play operation through universal serial bus (USB) ensures easy setup and installation.
• Data Over Cable Service Interface Specification (DOCSIS) compliance ensures
interoperability with DOCSIS compliant cable operators.
*NOTE: Speeds may vary based on the following factors:
• Computer equipment including available RAM and processor speed
• Software applications utilizing your computer’s resources
• Network traffic depending on the time of day
• Limitations set by your Cable Service Provider

NAT
Network Address Translation/Port Address Translation (NAT/PAT) gateway is designed for IP address
simplification and conservation, as it enables private IP network that uses no registered IP addresses to
connect to the Internet. NAT/PAT operates on a cable modem router, connecting to Internet, and translates
the private (not globally unique) addresses in the internal network into legal addresses before packets are
forwarded onto the Internet. As part of this functionality, NAT can be configured to advertise only one
address for the entire network to the outside world. This provides additional security, effectively hiding the
entire internal network from the world behind that address. NAT has the dual functionality of security and
address conservation, and is typically implemented in remote access environments.

Router IP address. The standard MAC access list performs frame filtering based on source MAC address
from the CPE host(s). Basically, the access list works as a source address packet filter, if the access list is
empty, the cable router will forward any packet, if access list is not empty, packet filtering will be enforced
according to the access list(s).
