What is DSL?

DSL, or Digital Subscriber Line, is a powerful technology that expands the capability of your local phone line and can increase your Internet connection up to 40 times faster. DSL allows users to obtain high-speed access to the Internet over existing phone lines, without purchasing an additional line. A DSL modem on your phone line splits your single phone line into two frequencies - one for data and one for voice. This allows you to make and receive phone calls without interrupting your Internet connection.

With DSL connection speeds can reach up to 384 Kbps (kilobits per second) upstream (from your computer to the remote computer location - the internet) and up to 1.5 Mbps (megabits per second) downstream (from the remote location to your computer).

How DSL Works

DSL Electronically expands the capacity of existing copper wire.

Computers will operate at the high frequency portion of the line, with phone and analog equipment operating at the lower frequencies of the line.

One phone line delivers voice and a high-speed Internet connection.

Voice/fax calls only use the frequencies below 4 kHz.

Frequencies above 4 kHz are reserved for data transmission.

Top Speed Comparison of Your Current Internet Telephone Access

- Analog Phone Modem: 28,800 up to 56K bps
- ISDN (Integrated Services Digital Network): 128K bps
- Digital Subscriber Line (DSL): Download up to 1.5-8 Million bps, Upload up to 640,000 bps

Benefits of DSL

- Because the information is transmitted separately from the voice/fax calls, your Internet connection can stay on all the time
- No more logging on and off - you are always connected
- No more busy signals – when you connect or when you get a phone call
- No more waiting…just open your browser and go!

Dedicated Connection

Currently, with cable modems:

- Customers share line with other users in neighborhood
- Connection speed is affected by how much bandwidth others use
- The dedicated connection that DSL uses provides more security than cable
- Cable modem users share bandwidth with their neighbors. Information traveling across the network is easier to intercept than information traveling on a DSL connection.
