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. |

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.
