What
is DSL?
| DSL
is an industry acronym for Digital Subscriber
Line. DSL is a system for transmitting digital
data over ordinary copper lines. This service
is available to individual subscribers with
a special router that transmits the digital
signals to a backbone network. Using your
existing telephone line, DSL allows speeds
up to 8Mbps. That is 50 times faster than
28.8k modems. The service lets you send
data and voice over the same line so you
can talk or fax while you surf. |

What
is G.lite ADSL?
| G.lite
ADSL allows for high-speed "always on"
digital communications over standard copper
lines. The customer simply connects the
G.lite Modem (the same way you would hook-up
an analog modem) after he signs up for the
service. Unlike standard of full-rate ADSL,
G.lite ADSL works with DLC. The tradeoff for
the increased availability of G.lite ADSL is
lower speed. While standard or full-rate
ADSL provides downstream speeds of up to
8mbps and upstream speeds of 1Mbps, G.lite ADSL
is limited to 1.5Mbps download and 512Kbps
upstream. |

What
is Full Rate (G.DMT) ADSL?
| ADSL
is an industry acronym for Asymmetric Digital
Subscriber Line. ADSL is a technology for
transmitting digital information at high
bandwidths on existing telephone lines to
home and businesses. ADSL simultaneously
accommodates both analog (voice) and digital
data on the same line. Unlike regular dial-up
telephone services, ADSL provides a continuously
available connection. ADSL is asymmetric
in that it uses most of the channel to transmit
downstream to the user and only a small
part to receive information from the user.
Full Rate (G.DMT) ADSL is generally offered at downstream
data rates up to 8Mbps. |

How
does DSL work?
| DSL
service providers use the same copper-based
lines that let you make and receive telephone
calls. To send data at high speeds:
- Carriers
use the lines' higher frequencies that
telephone service doesn't need.
- DSL
modems are hooked up at both ends of
a telephone line -- one in the home,
the other in the nearest telephone company
switching station.
- The
modems digitally divide your telephone
line into three channels: One handles
telephone traffic, one handles upstream
data from your computer to the Internet;
and the third handles downstream data
traffic from the Internet to your computer.

What
are DSL's major advantages?
| It's
fast. It's always on. It doesn't tie up
your telephone while you're online as
a so-called "dial-up" service
does. And it won't interfere with caller
ID, call waiting or other telephone features.
