DSL, or Digital Subscriber Line technology, connects your computer to the internet using the existing home phone line wiring.
Unlike dial up, a DSL connection does not tie up the phone, and leaves you free to make phone calls without interrupting your home phone connection. This is because it utilises a separate frequency to the phone call frequency.
How Does DSL Work?
DSL requires an active home phone connection, unless a ‘naked’ plan is purchased. A DSL connection also requires a modem to connect to the internet. The modem is connected to the computer, and then into the telephone outlet at the wall.
The modem takes the computer’s digital signals and turns them into voltage that is then sent across the telephone line to a central hub (a Digital Subscriber Line Access Multiplier, or DSLAM). The DSLAM serves as a switchboard, routing requests and responses between each client’s IP address and the internet.
