Wireless Cable Gateway Overview
Cable Internet Service Requirements
• Cable company that offers EURO-DOCSIS-compliant Internet services
What the Wireless Cable Gateway Does
The Digital Wireless Cable Gatewa y serves as a two-way high-speed bridge between your
personal computer and a cable Internet Service Provider (ISP). It converts information that
originates from the Internet or your computer into electronic messages that can be transported
over the same wires your cable company uses to transport video signals.
What the Wireless Cable Gateway Needs to Do Its Job
• The Right Cable Company: Make sure your cable company provides da ta services that use
cable TV industry-standard EURO-DOCSIS technology.
• The Internet Service P rovi de r ( ISP) : Your cable company provides you access to an Internet
Service Prov ider (ISP). The ISP is you r ga tew ay to the Internet. It provides you with a pipeline
to access Internet content on the World Wide Web ( WWW).
Check with your cable company to make sure you have everything you need to begin; they’ll
know if you need to install special software or re-configure your computer to make your cable
Internet service work for you.

Chapter 1: Connections and Setup
System Overview
The Wireless Cable Gateway is connected between your cab le c om p any and the PCs w ithin y our
home, as pictured previously in the Wireless Cable Gateway Overview. The connection to the
cable company is made by a coaxial cable, and is referred to as the WAN (Wide Area Network)
side of your Wireless Cable Gateway. The connections to your PCs are made by your choice of
several standard home networking methods: Ethernet, USB, or 802.11b Wireless, and are
referred to as the LAN (Local Area Network) side of your Wireless Cable Gateway. Multiple PCs
can use any or all of the LAN side connections simultaneously to share your single cable
company connection, up to a maximum of 254 PCs total.
Unlike a simple hub or switch, the gateway’s setup consists of more than simply plugging
hardware together. You’ll need to configu re your netw orked P Cs to ac cep t the IP a dd ress es the
gateway assigns them (if applicable), and you will also need to configure the gateway with
settings provided by your cable company.

The Cable Modem section of the gateway proceeds with EURO-DOCSIS initialization. In this
process, the CM performs the following sequence of steps. For a newly-installed gateway, this
can take as much as 2 0 m inutes to comp lete.
• Tuning - searching for a downstream EURO-DOCSIS CM signal
• Ranging - establishing 2-way communication with the cable company
• Connecting - obtaining the CM IP Address (for IP Stack 1)
Illu strations contained in this document are for representation only.
