What is ADSL?

DSL (Digital Subscriber Line) is a technology used for accessing public or private data networks over a copper circuit. To put it short, the DSL modems turn a regular copper circuit into a high-speed digital flux. The main applications of the DSL technology are broadband Internet (including all related services) and the deployment of corporate networks for companies that operate from a number of locations across the city. Due to their large bandwith, the DSL networks are suitable as a support for integrated services such as data, voice, video.The exponential growth in number of DSL connections around the world has been determined by the fact that DSL connections are easy to install and by the price-to-quality ratio that is significantly superior compared to other technologies.
ADSL (Asymetrical Digital subscriber Line) is a branch of the DSL technology thst takes advantage of a common behaviour among Internet users. In most cases, the volume of data coming towards the client (the download) is much bigger than the volume of data leaving the client (the upload). The ADSL equipments allow 8Mbps/1Mbps links to be established (26Mbps/3Mbps for ADSL2+) using a digital coding technique, and thus not interfering with the conventional voice services that share the same line.
