DSL - Part 1

by Michael E. Callahan aka Dr. File Finder


This question submitted by Andy Watson, Janet Pullman, RobertoSamson, Aliyah Verner, Paula VanDam, and numerous others

I've received so many different kinds of questions about DSL thatI've decided to respond with a two-part article. I hope you'll find itinformative.

In recent years more and more people have gotten "high-speed"Internet connections. At the same time as more people get computers andgo online there are more people who want a high-speed connection. High-speed or "broadband" connections can be obtained through cable,satellite, and "Digital Subscriber Lines or DSL. How doesDSL work? Lets take a brief look.

What DSL actually does is take advantage of all the extra "bandwidth"that is available in your standard phone. The wires in your phone cancarry your voice, but that only uses a tiny fraction of the potentialbandwidth. DSL technology takes advantage of the extra. DSL, which isalso called ADSL (Asymmetric Digital Subscriber Line), takes the datafrom your computer and transfers it to your provider, normally yourphone company. Once there, your data is combined with that of many othercustomers and is shot off to the Internet.

One current drawback to DSL is distance. In order to get DSL youhave to be within 18,000 feet or 3.4 miles of the phone companies DSLequipment. The further the distance the slower the speed and the lowerthe quality. So, for example, a person located 5,000 feet from theequipment would have better service than a customer located at say17,000 feet.

So, that's the basics of DSL. Next week I'll talk about someevolving technologies like VDSL, which is a new type of high-speedconnection that delivers speeds up to 52 megabits! At that speedyou're really moving some data and that the kind of connection you'llneed to multiple services bundled in one line. So, stay tuned and joinme next week for part 2.

I'd like to thank Andy Watson, Janet Pullman, Roberto Samson, AliyahVerner, Paula VanDam and numerous others for asking this question.
