PDF of this tutorialDSL technology is a new platform for delivering broadband services to homes and small businesses. DSL can support a wide variety of high-bandwidth applications, such as high-speed Internet access, telecommuting, virtual private networking, and streaming multimedia content. In the past, these services were either not possible to support or were ineffectively supported by conventional, dial-up, data-delivery technologies. DSL can transmit more than 8 Mbps to a subscriber—enough to provide Internet access, video on demand (VOD), and local-area network (LAN) access. This increases the existing access capacity by more than fiftyfold, enabling the transformation of the existing public network. No longer is this network limited to voice, text, and low-resolution graphics. It promises to be nothing less than a ubiquitous system that can provide multimedia (including full-motion video) around the globe.
To enable this technology, service providers must have a DSLAM located in their networks to interact with the customer premises equipment (CPE) at the end-user location.
