What is possible with xDSL?
xDSL enables two general types of applications — interactive video and high speed data communications. Interactive video includes movies on demand, other video on demand such as delayed TV segments, video games, video catalogs, and video information retrieval. Data communications covers Internet access, telecommuting (remote LAN access), and specialized network access. The strength of xDSL compared to other high speed transmission alternatives [such as cable modems or Fiber To The Neighborhood (FTTN)] lies in the number of existing telephone lines — now approaching 750 million — compared to new cabling which has reached comparatively few homes and almost no small businesses.
