Using asymmetric digital subscriber line (ADSL) for fast Internet and multimedia services

摘要

In this paper the design of an experimental ADSL network and the applications used are presented. Digital subscriber line (DSL) technologies enable the use of twisted pair copper telephone lines, that reach practically every home and business (public switched telephone network) with very large bandwidth, typically from 1.5-6 Mbps downstream and 640 kbps upstream, by placing a pair of modems at the user (home) and at the C.O. (PTT Central Office) side. After a small introduction on broadband access networks the design of an experimental ADSL network is presented. Furthermore, the design of high bandwidth, rich in content applications taking advantage of the high speed ADSL network is given.
