a lot of talk these days about high-speed access and the Internet. Who´s
got the fastest service? What equipment do you need? Is it available in
your area? The choices are many and, quite often, confusing. One thing
you can be sure of, DSL is the most practical technology for the future.
Subscriber Line) technology works on the existing copper telephone line
already in your house, also known as a "twisted pair". It uses
sophisticated digital coding to utilize more of the existing space on
the wire, without interfering with your normal phone conversations. And,
it´s fast... Really fast. With ADSL download speed at up to 8Mb/s
it´s 200 times faster than traditional analog modems.
comes in different flavors, with
ADSL and SHDSL as the
most renowned of all of them.
That brings us
to point number two. It´s always "on". There´s no
dial-up as is required with conventional analog modems, and no need for
a second line for phone calls while you work, or surf. Unlike cable modems,
DSL is not shared among users and so its speed and capacity are not affected
by how many subscribers are using the service at the same time. The line
is there for you and you alone.
And third, the
infrastructure to support DSL is already in place. Today, there are nearly
750 million existing copper lines worldwide available to support DSL services.
By comparison, no more than 12 million homes are served today by cable
systems that can support two-way cable modem transmission.
When you add
it up, DSL is the clear choice for affordable high-speed remote access
to the Internet, telecommuting and other advanced on-line services.
