What
is ADSL?
ADSL
stands for Asymmetric Digital Subscriber Line. It is the broadband
technology used to transmit digital information at high speeds over
existing phone lines. Unlike dialup Internet, ADSL can provide an
almost continuous connection to the Internet. The connections are
asymmetric in terms of download speeds being greater than upload
speeds.
What
are the benefits of having ADSL?
ADSL
provides an almost continuous connection to the Internet which means
you do not have to pay the cost of a phone call each time you connect.
In addition, you can use a phone or fax machine on the same line
when you are connected to the Internet. ADSL download speed is typically
5 to 50 times faster than an ordinary dialup connection. A dialup
modem is typically capable of 40-52 kbps connection speeds (depending
on factors such as telephone line quality), whereas basic ADSL plans
start at a download speed of 256 kbps and maximum upload speed of
64 kbps.
Speeds
of 256/64k, 512/128k and 1500/256k are commonly available, but in
mid-2007 Telstra lifted the 1,500 kbps cap they had at their exchanges,
so the maximum download speed of ADSL1 is 8,000 kbps, but this speed
drops off with distance from the exchange.
What
is ADSL2 and ADSL2+?
The
next generation, ADSL2, has a theoretical throughput of 18,000 kbps
was soon followed by ADSL2+ which has a maximum download speed of
24,000 kbps, but the actual speed is very much dependent upon line
quality and distance from the exchange. For more background, and
information ADSL2+ plans, please see: http://futureweb.com.au/adsl/adsl2.asp
ADSL2+
also extends the availability range from the original ADSL limit
of about 4.3 Km from the exchange, to about 7.5 Km, allowing accessibility
to some customers that previously were unable to have ADSL.
Speed
Comparisons
An
average MP3 file of 4MB would take about 10 minutes at the theoretical
maximum rate of DialUp 56kbps. The same file would take about 2.1
minutes on a 256kbps ADSL plan, just over a minute at 512kbps, around
22 seconds at 1500kbps, only 4 seconds on one of FutureWeb's 8,000kbps
plans, or a blazing one and a half seconds at the theoretical maximum
24,000kbps of ADSL2+ (but note that very few users will be able
to achieve this speed, which depends not only on line quality, but
on distance from the exchange and other factors *see below). And
even if you are lucky enough to get very high speed, remember that
Internet congestion and the specifications of the webserver and
link size at the source location are likely to limit actual download
speeds.

Can
I get ADSL / ADSL2+?
Click
here to check availability
of the service in your area. ADSL line provisioning takes between
5 and 20 working days (average is 3 to 5 days). However, it can
take longer if there are complications.
What
do I need to do to get ADSL?
Firstly,
you need to check that ADSL is available in your area and choose
a plan that will best suit your needs. If you do not currently have
an ADSL modem/router, you can purchase one from FutureWeb or most
computer retail outlets. Once the modem/router is installed and
configured to connect to FutureWeb, you should be ready to use ADSL.
Customers
may optionally select FutureWeb as their Long Distance Telephone
Call provider with ADSL Plans to receive a discount for bundling,
but a contractural requirement of the reseller of ADSL2+ is that
the customer uses FutureWeb as their provider of Local Calls.
What
is a splitter/filter and do I need one?
A
splitter or line filter separates the standard phone line signals
from the DSL signals. This is required in order to use the phone
line for standard phone handsets, modems, fax machines or other
devices that require the phone line. Each and every telephone device
on that phone line, that plugs into wall requires a line filter.
Most
ADSL modem/routers come with a splitter or filter. The specification
sheet for the modem/router will usually tell you if this device
is included.
Where
do I get help to install an ADSL modem?
Futureweb
can supply a competitively priced ADSL modem that is preconfigured
with username, password, protocols and other settings. If a ADSL
modems/router is self-supplied, it should have simple instructions
detailing their setup and configuration. Due to the large number
of modems on the markekt, FutureWeb is unable to give phone support
for a user-supplied device, nor support the configuration of any
additional advanced features, such as port-forwarding or wireless
settings, as this is the responsibility of the end user.
Will
I receive a static IP address?
If
required, a static IP (Internet Protocol) address can be included
with all ADSL plans. This permanent IP address is used to uniquely
identify your Internet connection and is essential for running various
services such as Virtual Private Networking and onsite mail servers.
However, a static IP may increase the risk of your network being
targeted by hackers and should only be requested if you are running
such services.
Where
do I get technical assistance?
FutureWeb
offers telephone technical support on 1300 361 355 or via email
at support@futureweb.com.au
On site assistance is also available in selected locations at additional
cost.
