Information on a DSL Connection Link

A digital subscriber line (DSL) is a connection between an Internet user and their Internet service provider (ISP). DSL Internet services are usually provided by telephone providers, because they use existing phone lines.

Equipment

A DSL connection requires the use of specialized hardware at each end of the connection to maintain continuous Internet access. A subscriber to the service requires a modem to receive and transmit information.

Frequency

DSL connections allow simultaneous use of the Internet and a telephone using the same copper telephone line. The movement of data is transmitted at a higher frequency than voice data is passed along the connection allowing both to be used simultaneously.

Asymmetric

The most common form of DSL connection used in residential Internet usage is asymmetric DSL. This allows a larger amount of information to be sent to a user, including video and audio files with less transmitted from the user to the ISP, usually keystrokes and mouse movements.
