Fast internet access by ADSL technology:
via standard (copper) telephone lines
Since the early 1990s, it has been possible to interconnect a television receiver with the telephone system to provide a user interactive data service. A few years later, it was found that when Asymmetrical Digital Subscriber Line (ADSL) technology is used, a Video On Demand (VOD) service can be implemented. Since then researchers have discovered that ADSL provides an opportunity of significantly increasing the speed of access to the Internet. This article describes the basics of the ADSL technology and how it may be used to access the Internet at high speed.
