INTRODUCTION
The Motorola CG3500 Communications Gateway cable modem enables you to connect your home or business computer to a
high-speed Data Over Cable Service Interface Specification (DOCSIS) 1.0 or 1.1 compliant data network. The CG3500 provides
high-speed, bi-directional data access with Radio Frequency (RF) downstream transfer rates up to 38 Mbps and RF upstream
rates up to 10 Mbps. It also provides telephony voice communication features using the Internet Protocol (IP) known as Voice
over IP (VoIP).
Unlike a dial-up modem, the CG3500 is always online. Just open your browser and surf.
