What is ADSL?
Asymmetric Digital Subscriber Line technology sends and receives data
at high speeds over copper telephone lines. It is called
"asymmetric" because the speed of receiving data different than the
speed of sending data. Higher performance varies on line conditions and
distance from the switch. ADSL requires a special modem
designed for the higher speeds that connects to a telephone jack
similar to a conventional modem. Most ADSL modem products
connect to a computer with a 10 Base-T network adapter (NIC). How
do cable modems differ from ADSL service?
Cable modems, like ADSL are a faster alternative to conventional
56k connections. Unlike ADSL, cable modems share bandwidth with
all users in a particular area. If a user on the same block is
downloading large files, all users will experience slower
speeds. With ADSL, each user is provided with their own
dedicated connection, thus avoiding a performance hit seen with a
cable modem setup. For more information on the differences
between DSL and Cable, please review our comparison. How far is the service area from
the TELCO switching station?
ADSL service area is approximately 21,000 cable feet. After
that point, quality is too low to benefit from ADSL service.
Customers who are outside the ADSL subscription area may want to look
at alternatives such as ISDN solutions. Is ADSL a
business solution?
ADSL is an ideal solution for small to mid sized businesses
looking for a cost effective way to provide Internet access at their
organization. Customers looking to run mission critical
applications such as web and ftp servers should consider T-1 solutions
for expanded reliability and performance. More information on
Dedicated connections such as T-1 lines can be found in the Dedicated
Access section of our website. |
