Digital Subscriber Line
Imagine a world where connecting to the Internet was as simple as turning
on
your television. Where web pages pop up on the screen like we would all
like for
them to. We are all aware that WWW is an a acronym that stands for
World Wide
Web, however, it turns out to be World Wide Wait. But now, in
most places, the
World Wide Wait is over. There is a new technology DSL.
Digital Subscriber Line,
or DSL is a new technology for bringing high –
bandwidth connection to
Internet service for both business and homes over
ordinary copper telephone
lines. DSL is a reference to family of digital
subscribers to line technologies.
The connection of speed for DSL ranges
forms 1.544 MBPS to 512 KBPS. DSL lines
allow for one line to carry both
voice and data signals, and the data part is
continuously connected. It has a
higher transfer rate, and it has more available
spectrum. Our ordinary
telephone service only makes use of the 0-3400 Hz
frequency ranges, which
means 56 KBPS speed limits on a standard modem. DSL is
relatively new. Not
many people are familiar with this new technology yet.
It’s a service
that everyone should have if they are using a standard dial-up
connection,
and prefer to have a faster Internet connection. DSL is the use of
existing
twisted pair of wires that make it cheaper to install, and which does
not
require additional cables to be laid. And, unlike other modems DSL is not
a
bus technology. DSL requires no additional phone lines. It gives the user
24hour
access, and it does not tie up the phone line. So the user never has a
busy
signal while they are on line. Most ISPs offer a range of speed so the
user can
choose the speed they prefer to use. ADSL is the type of DSL that is
preferred
for small business and homes. It will allow the user to download
data faster
than they can send data. Despite all these positive attributes,
DSL is not
without a flaw. For example, for a user to be eligible for DSL,
the user must be
geographically located within a certain distance from the
telephone office. DSL
service and availability is still in early stages.
Prices in most areas are
considered to be very high. Prices can change over
night just like the way they
would for everything else. Price range varies;
it all depends on the service
provider and it’s surrounding area. Local
taxes, and government regulations
may also determine users cost. In most
cases, the user must pay for the cost of
hooking up DSL lines, and the
monthly charges from the phone company. If the
user chooses to use a provider
other than the phone company it’s estimated
cost is about $100 a month extra.
It all begins with a phone call to your
telephone company. From there the
ordering process starts. The telephone company
first determines if you are
calling form an area where DSL is available. Then,
if the user is close
enough the telephone company runs a test through to see if
the wires will be
able to handle the bandwidth needed for DSL. For DSL to be
installed the
phone company will place a splitter in the box of your location.
This
allows the user to use voice service while using DSL. Then it’s all plug
and
plays from there unless you are connecting a network. DSL is not available
in
many areas yet. Mainly because of distance problems, or because the
local
telephone companies have not yet acquaint this product. But with DSL,
technology
is developing rapidly, it will soon be introduce by many
companies. Efforts will
be made to improve the transmission over greater
distance. This technology is
still in the early stages of roll out with
standards, and products just getting
under way.
