The Future of Digital Subscriber Line Technology: Business Drivers, Strategies, and Markets


As the Internet market continues to explode, consumer and business demand for greater bandwidth and faster connection speeds has led to several technological approaches. Prominent among them are digital subscriber line (DSL) technologies, which are being installed at an unprecedented rate. Projections as high as 6 million lines installed—generating $5.5 billion—by 2002 exist for the U.S. DSL market alone. To meet such projections, it is imperative that service providers stay abreast of recent developments.

Addressing one of the most important topics to the telecom and information industries today, The Future of DSL provides an overview of DSL deployment and explores the forces driving the rapid growth of broadband and high-speed access in homes and businesses.

The report provides an examination of regulatory constraints, technology hurdles, market drivers, current trials and installations, and competing technologies, as it offers in-depth discussion about the future of DSL. This comprehensive report also provides key definitions and background information for a well-rounded view of the technology.
