Overview:
ADSL (Asymmetric Digital Subscriber Line) technology is made resurgence in 1996 as telcos look for alternatives to costly network infrastructure upgrades such as HFC and fiber to the curb. ADSL takes the existing copper telephone line and turns it into a digital pathway capable of carrying up to 8 Mbps downstream and 1 Mbps upstream, making it ideal for high-speed Internet access services, telecommuting, remote LAN access and other emerging residential broadband applications. ADSL technology can also be used in business environments as a high-speed link between corporate intranets, or a low-cost alternative to T-1 and Fractional T-1 lines. This report provides an in-depth look at ADSL, as well as other DSL technologies (HDSL, SDSL, VDSL), and their potential for success in the highly competitive local loop.
