data traffic on specific channels in broadcast to the whole network. When the cable modem powers up, it scans all channels using a hardware tuner, and traffic gradually starts streaming using a state machine. A handshake procedure between the cable modem and the CMTS is initiated through a software code running on the cable modem. Gradually, the cable modem locks on all channels, becomes operational, and can pass the traffic. When the handshake process fails, there is a time out during which the cable modem tries the failed step of the process again. If the cable modem is unsuccessful, it starts the process from the beginning. Intel and the DOCSIS Device Market Intel is a leading provider of DOCSIS network solutions for cable modems and gateways and much of the product development happens in Israel. Intel has also been investing in and leading cable broadband innovations for many years to speed innovation, including playing a leading role in the development of DOCSIS specifications. The Intel ® Puma™ 7 SoC 10 is a leading DOCSIS 3.1 solution that enables support for increased bandwidth, is architected for a wide

range of use cases on the WAN and LAN side, and is being implemented in a range of devices worldwide. Intel also offers a portfolio of Wi-Fi and Ethernet solutions that are optimized for use with Intel Puma SoCs for integrated home gateway platforms that can deliver high-performance connectivity. Summary The DOCSIS specification is the leading specification for internet services and is widely deployed worldwide. It meets consumer demand for high-speed connections and sophisticated applications by improving broadband speed, quality of experience, energy efficiency and capacity and has paved the way for high-bandwidth broadband with one gigabit speeds available to more than 80 percent of U.S. cable households today. Full Duplex DOCSIS, with symmetrical speeds, will expand upon that groundwork and will make it possible to deliver multi-gigabit upload and download speeds over the connections already present in hundreds of millions of homes. It is a significant piece of the 10 Gigabit platform, supported by Intel, Internet service providers and others. Cable specification continues to innovate and evolve to keep up with increasing demand for bandwidth, and more connected devices in the home.
