How Does DSL Work?

Understanding How DSL Works

DSL is now a standard favorite among the high-speed, broadband Internet connections.  DSL works with a twisted pair of copper wires, just like the kind that connects to your telephone from the telephone company.

When you are hooked up to a DSL Internet connection, your traditional phone line becomes the medium for all of your voice conversations and your Internet data requests.  Just like in a cable connection, the line is shared by the two connections and the information is kept separate, so that signals do not cross. 

DSL Filters

A filter is sometimes used to separate the information coming from voice conversations and from the Internet.  All signals under 4Khz are voice signals, everything over 4Khz is Internet data either being uploaded or downloaded.  The filter acts as a barrier so that signals never cross. 

DSL Equipment

There are two important pieces of equipment that make a DSL Internet connection possible:

• A transceiver (also known as a modem) – on the subscriber’s side, this hooks up the computer to the phone line and processes all information and data.
• DSLAM – on the service provider’s side, stands for DSL Access Multiplexer and it takes requests from many customers and sends them into a single connection to the Internet.

Pros of DSL High Speed Internet Access

DSL is like all the other Internet connections in that it has its quirks and its benefits.  Here are some things you can look forward to:

• You can use the Internet and the phone at the same time, or leave the Internet on and still make and receive phone calls.
• DSL can support very high speeds, especially if you are on a shorter loop (meaning you are closer to the central office).
• Sometimes your existing phone lines can be used to run your connection, meaning no additional installation.
• Some DSL ISPs will provide a modem with your installation.

Cons of DSL High Speed Internet Access

Let’s face it, DSL has its downsides.  Read on to find out what they are and if you can live with them or not!

• Your connection will be much faster if you live closer to the provider’s central office.
• It is faster to download than upload.
• Not everyone can get DSL because of the proximity issue.
