announced. The new specification enhanced DOCSIS 1.0 to include support for cable telephony using VoIP technology, streaming video and managed data services. In 2002 DOCSIS 2.0 was approved. DOCSIS 2.0 adds support for higher upstream transmission speeds of up to 30 Mbps and more symmetric IP services, and provides extra capacity for cable telephony. The high speeds of today’s cable can enable an entirely new generation of multimedia-rich content over the Internet and allow cable operators to expand their traditional video product offerings to include data and telephone services. The adoption of cable services and the continued proliferation of homes with multiple PCs have also generated the need for residential networking. operators have recognized the opportunity to include this feature in the equipment they utilize for services through either home telephone line or wireless solutions, and the cable industry has created a specification called CableHomeTM that defines how a home intranet interoperates with a cable operator’s Internet service. We offer integrated semiconductor solutions for cable modems and cable modem termination systems. We currently have a leading market position in both equipment areas, with an extensive product offering for the high-speed, two-way transmission of voice, video and data services to residential customers. We offer a complete system-level solution that not only includes integrated circuits, but also reference design hardware and a full software suite to support our customers’ needs and accelerate their time to market. Cable Modem Solutions. All of our cable modem chips are built around our QAMLink˛ DOCSIS- compliant transceiver and media access controller, or MAC, technologies. These technologies enable downstream data rates up to 56 Mbps and upstream data rates up to 30 Mbps and are compliant with DOCSIS versions 1.0, 1.1 and 2.0. These devices provide a complete DOCSIS system solution in silicon, enabling to support constant bit rate services like VoIP and video streaming. Residential Gateway Solutions. The levels of integration and performance that we continue to achieve in our cable modem chips are reducing the cost and size of cable modems while providing consumers with easy to use features and seamless integration to other transmission media. As a result, cable modem functionality is evolving into a small silicon core that can be incorporated into other consumer devices for broader distribution of IP-based services throughout the home. Broadcom offers residential broadband gateway solutions that bring together a range of capabilities, including those for cable modems, digital set-top boxes, home networking, VoIP and connectivity. These products allow cable operators worldwide to provide residential broadband gateways capable of delivering digital telephone service via the PacketCableTM specification, IP video, and cable modem Internet services, as well as data home networking over in-home Ethernet or wireless networks. CMTS Solutions. We have a complete end-to-end DOCSIS 1.0, 1.1 and 2.0 compliant cable modem semiconductor solution for both head-end and subscriber locations. Our CMTS chipset consists of downstream and upstream , or PHY, devices and a DOCSIS MAC. This cable modem termination system enables the exchange of information to and from the subscriber location, making it a key element in the delivery of broadband access over cable.

DSL

Digital subscriber line technologies, commonly known as DSL, represent a family of broadband technologies that use a greater range of frequencies over existing telephone lines than traditional telephone services. This provides greater bandwidth to send and receive information. DSL speeds range from 128 Kbps to 52 Mbps depending upon the particular DSL standard and the distance between the central office and the subscriber. These data rates allow local exchange carriers to provide, and end users to receive, a wide range of new broadband services. DSL technology has a number of standards or line codes used worldwide. We support all standards-based line codes, such as asymmetric DSL, or ADSL, ADSL2, ADSL2+ and very-high-speed DSL, or VDSL, including the standard Annexes used in North America, Europe, Japan and China. In addition, we provide end-to-end technology, with solutions designed for both customer premises equipment, or CPE, and central office applications. Our DSL technologies enable local exchange carriers and enterprise networking vendors to deliver
