What is DSL internet?
DSL (Digital Subscriber Line) is a proven technology that offers secure, high-speed Internet access over existing copper lines. DSL can provide you with T1-like speeds up to 50 times faster than a 28.8Kbps modem. This is possible because digital communications can squeeze more capacity out of a phone line than analog modems.

Since the telephone company’s signaling is already set up for this analog wave transmission, it’s easier to use that as the way to get information back and forth between your telephone and the telephone company. This is the reason why your computer must have a modem! The modem receives and translates the analog signal, and then converts the analog values into digital information. Analog transmission only uses a small portion of the available amount of information that could be t
