DSL Forum

It seems everyone is on the "net" these days, and as more homes gain multiple computers and adopt broadband, the interest in networking those computers and other devices has increased. By the end of 2010, the DSLF has established a goal of 500 million subscribers around the world to have a high-speed DSL connection. In its new report, "Worldwide Home Networking 2004-2008 Forecast and Analysis," IDC expects home network households to grow 25% to 111 million by 2008. And according to DLNA (Digital Living Network Alliance), research predicts that 52 % of online households in America will have home networks by 2008.

This guide focuses on explaining the basic components users will need for this home networking explosion, and highlights the various services and applications that users will enjoy with a home network. Home networking shouldn¹t stand-alone though, and only with a fast, quality Internet connection can the online family really get the full benefit of their network. Digital Subscriber Line (DSL) provides the online family with the speed they need to reach the full potential of online life.

Overview: Over the last several years, DSL service has experienced ever-increasing demand from the subscriber community. However, a portion of the world-wide user community continues to be unable to get DSL service because they are either located at too great a distance from the service provider's central office (CO) or they are not served by a copper loop directly from the CO. In addition, the need to support higher-bandwidth solutions such as on-demand video services has driven the need for continuous innovation in DSL technologies.

This paper offers architectural solutions and techniques for both extending DSL coverage to help service providers deploy 'DSL Anywhere', as well as new technologies to support ever-increasing bandwidth requirements.

ADSL2 AND ADSL2plus - THE NEW ADSL STANDARDS (Download)

Overview: ADSL2 (ITU G.992.3 and G.992.4) adds new features and functionality targeted at improving performance and interoperability, and adds support for new applications, services and deployment scenarios. Among the changes are improvements in data rate and reach performance, rate adaptation, diagnostics and stand-by mode, to name a few.

ADSL2plus (ITU G.992.5) doubles the bandwidth used for downstream data transmission, effectively doubling the maximum downstream data rates, and achieving rates of 20 Mbps on phone lines as long at 5,000 feet. ADSL2plus solutions will most commonly be multimodal, interoperating with ADSL and ADSL2, as well as with ADSL2plus chipsets. More detail about ADSL2plus is included later in this paper.
