Digital Subscriber Line (DSL) is a technology that provides a dedicated digital circuit between a residence and a telephone company’s central office, allowing high-speed data transport over existing telephone lines.
Typically, there is a modem on either end; one modem is located at the central office, and the other at the
customer’s site. There are several types of DSL including ADSL, HDSL, IDSL, SDSL, and VDSL, but of these, the most common, at least in the UK and India is ADSL. ADSL (Asymmetric Digital Subscriber Line) is designed to deliver more bandwidth downstream (from the central office to the customer site) than upstream (that’s why the word “asymmetric”).
SDSL, common in Europe, is the Symmetric Digital Subscriber Line, a technology that allows the same data rates for upstream as well as downstream traffic, over existing copper telephone lines. However, it doesn’t allow simultaneously voice connections on the same wires.
