What Is DSL Internet
DSL Internet or Digital Subscriber Line can get you surfing at 128 Kbps and can go up to a max speed of 24000Kbps. Some of the advantages of DSL are that you can talk on your phone even while you are surfing the net, you don't need to provide new wiring, Internet speed is faster, and you can view high flash websites, download songs or movies, and play games.

The disadvantages are that you can't get DSL in all areas because you need a telephone line, your speed decreases the farther you get from the area around a phone company, and the price is higher than dial up which give you cheaper Internet.

Existing copper pair phone line wiring is used by DSL Internet in conjunction with special hardware on the switch and user ends of the line. This special type of hardware allows you to have a continuous digital connection over the phone line so that you don't have to continuously phone in as with dial-up. Since the DSL connection is digital its technology doesn't have a digital-to-analog conversion like the traditional modems. DSL can use frequencies above the voice audio spectrum so that you can use your phone even while you are surfing the web.

The different kinds of frequencies allow DSL to encode more data and also allow Internet connection speeds of up to 50 times faster than standard modems and up to 12 times faster than ISDN connections. DSL offers bandwidth which is more consistent than cable modems where multiple users share very high bandwidth media. The most commonly available DSL technology is ADSL or asymmetric DSL since it is created to accommodate typical consumer Internet use with more data heading toward the user and less away from the user.

The receiving rate or downstream rate varies from 1.5 to 9 Mbps and the sending rate or upstream rate varies from 16 to 640 Kbps. These are dependent on the distance to the phone company's central office. You can find information online about other types of DSL such as CDSL (Consumer DSL), G Lite or DSL Lite, HDSL (High bit-rate Digital Subscriber Line), IDSL, RADSL (Rate-Adaptive DSL), SDSL (Symmetric DSL), UDSL (Unidirectional DSL) and VDSL (Very high data rate DSL) among other kinds depending on your specific needs.

DSL Internet modems follow the data rate multiples which have been established by North American and European standards. Overall the maximum range for DSL without a repeater is 5.5 km (18,000 ft,). DSL is now offered in most parts of the U.S., the U.K. and elsewhere. Its availability depends on whether your local phone company has made the necessary investment in equipment and line reconditioning and on your own location from your central phone company.

There are also guides available online which will provide with all the information about DSL that you need to make your decision about what type of DSL Internet service you need. You can also find out if the type you want is available in your area.
