What is ADSL?
ADSL stands for Asymmetric Digital Subscriber Line. It is always-on,
high-speed data communications technology that is delivered
using existing telephone lines. DSL refers
to the technology used between a customer's premises and
company, enabling more bandwidth over telephone lines than dial-up
modems or ISDN. It allows you be connected to the Internet
and make and receive calls on the same line at the same time.
How does DSL work? DSL runs over regular phone lines. DSL utilizes more of
the bandwidth capacity on copper phone lines than is currently
used for regular telephone service. By utilizing higher data
DSL can dramatically achieve faster data rates. In order to transform
a telephone line into a high-speed data line, DSL equipment must
be installed on both ends of the line - at the customer premises
(an ADSL capable modem)
and the local telephone central office.
ADSL - Asymmetrical Digital Subscriber
ADSL supports a range of asymmetric (different download and than
upload speeds) data speeds that can reach up to 1.5 mega-bits per
second (mbps) downstream and 256 kilo-bits per second (kbps) upstream.
ADSL can deliver simultaneous high-speed data and telephone services
over the same line
What's the difference between
ADSL and Cable Modem services?
There is not much difference between the two technologies from
the viewpoint of the end-user. Cable modems use Hybrid-Fibre-Coaxial
cables (the same cables that FOXTEL services use) to reach your
home or business whilst ADSL modems use your ordinary telephone
line. Both offer high speed Internet Services.
Benefits of ADSL
ADSL technology has the
make and receive telephone calls whilst on-line
Have it on 24 hours 7 days a week without any time based charges
No need to dial up, plus no local call charges
Speed - is 20 to 50 times faster than a conventional 56Kbits/sec
Example - download time for a 9MB
25 minutes at 56Kbps (PSTN)
10 minutes at 128Kbps (ISDN)
48 seconds at 1.5Mbps (ADSL)
Will all my PSTN telephone features work
Your telephone features will work as normal. However, we will
not be able to offer you an ADSL service if you currently use
some specific incompatible products. We are working to overcome
these limitations. Also there may be minor interruption to your
standard service during ADSL activation.
Do telephone lines need to be updated to
To continually improve service levels, Telecommunication carriers
have has an ongoing program to upgrade telephone lines. The vast
majority of telephone lines will not require any upgrade work
specifically to support an ADSL service. ADSL technology uses
a proven robust transmission technique specifically suited to
ordinary telephone lines.
What is involved in an ADSL service qualification
There are many requirements to be met before an ADSL service can
be provided. Not all telephone services belonging to an ADSL covered
exchange can necessarily have an ADSL service. A service qualification
check will test whether your telephone line will meet the following
Your telephone line belongs to an ADSL enabled exchange
Your home or business is within a certain distance from an
Your telephone line is a straight PSTN service without any
ADSL incompatible equipment such as PABXs, Commanders, OnRamp
services, pair gain systems etc
There are no incompatible products associated with your telephone
line such as EasyCall® Multiple Number or FaxStream Duet™
Why do I need a network adapter in my computer?
You will need a network adapter if you plan to use a DSL Ethernet
modem. An Ethernet modem is recommended if you are planning on
sharing the your ADSL connection with two or more computers.
DSL modems and routers use Ethernet because it provides the interface
capacity to support high-speed Internet connections and allows
multiple computers connected to a LAN. Ethernet is the most popular
form of local area networking. Setting up an Ethernet based LAN
for Microsoft Windows is inexpensive and relatively easy. You
can also get Ethernet adapters for notebooks in the form of PCMIA
(PC card) card. They're a little more expensive than desktop
How secure is my computer or LAN using an
always-on Internet Connection?
Any connection to the Internet carries some risks. At the very
least you should have an up to date Anti-Virus program install
and make sure it is updated regularly (at least once a week).
DSL provides a dedicated Internet connection over private
lines. This reduces the risk of your data being accessed by hackers
over a shared network. A DSL router can offer additional security.
For maximum security you should explore the use of a firewall
as well as other hardware and software solutions.
Does anyone have to visit my home or office
to install DSL?
In most cases no. ADSL is typically set up on an already existing
phone line. Work is done at the telephone exchange to enable
the phone line for ADSL. Once the line is enable and working
we send out an ADSL modem, if you have requested one. We can
organise for someone to come out to install the modem, however
our standard installation fees apply.
Will the self-installation of my new modem be easy?
Yes. Easy to follow instructions are supplied with each modem
that is sent out. However if you are having problems we are more
than happy to help you with the set up over the phone. If you
think you will need help we can organise for someone to come
out to install the modem, however our standard installation fees
What is CPE and what does it do?
CPE stands for 'Customer Premises Equipment' (or more commonly
known as your ADSL modem), which is the DSL equipment that connects
your home or business to the telephone line delivering DSL service.
DSL CPE provides two essential functions for your DSL Internet
connection. The first is converting the digital data from the
computer to a form of digital signaling used for the DSL communications
link. The second function of your DSL CPE is handing the IP (Internet
Protocol) networking to enable your computer or LAN to connect
to the Internet via your ISP. DSL CPE comes in two flavors: bridges
(a DSL modem) and routers.
How does DSL CPE connect
to my computer?
DSL CPE connects to the DSL service at one end and to your computer
or LAN at the other. DSL CPE can connect to your computer using
one of three following interfaces:
forms the basis of the most popular form of computer (PCs and
Macs) networking. You can connect Ethernet DSL CPE to a single
computer or a network. Ethernet is the most commonly used interface
for DSL CPE because it can easily support the speeds of DSL (up
to 100Mbps) and enables the DSL connection to be shared across
a network. Ethernet DSL CPE can be used with PCs and Mac's.
USB (Universal Serial
Bus). USB supports data speeds of up to 12Mbps between your computer
and peripherals. USB also allows you to easily connect comp0uter
peripherals, including a DSL modem, to a computer without cracking
the case to insert an adapter card. USB ports have been standard
on most PCs for the last few years and Microsoft Windows 98, Windows
2000, and the latest Macs support USB. A USB DSL modem is an external
device that connects to a USB port on your PC and is typically
used for consumer (single computer) DSL offerings.
PCI (Peripheral Component
Interconnect). PCI is a standard adapter card that inserts into
a slot inside your PC. Installing a PCI DSL modem isn't as easy
as installing an external USB modem. As is the case with USB modems,
PCI DSL modems are typically bundled with consumer (single computer)
I live in a block of units and the Body Corporate
cannot agree on cable access. Will there be a similar problem
No. ADSL uses your existing telephone line so there will be no
need to get permission from the Body Corporate to install high
speed access to the Internet via ADSL.
Can I take my ADSL service with me if I move
This depends on whether the premises that you are moving into
belongs to an ADSL enabled exchange. Relocating your ADSL service
can take up to 10 days and a service fee applies. A relocation
request needs to be made even if you are transferring your current
ADSL number to new premises. Please contact Hotkey before you
move to confirm whether you will be able to continue using the
What's static IP addressing?
A static IP address is a number that is assigned to a computer
when it is on the Internet. Computers use IP addresses to locate
and talk to each other on the Internet, much the same way. Static
IP addresses are assigned to a specific computer or other network
device on a permanent basis until manually changed, that is the
IP address is always the same. Typically a static IP address
is needed if you are running a web, mail or file severs.
What's dynamic IP addressing?
Dynamic IP addresses are kept in a pool of available IP addresses
and parceled out when users log on to the network. When a user
logs off the network, the IP address is returned to the pool of
available IP addresses to be used by another user. Because these
IP addresses are assigned on an as needed basis, the IP address
assigned to a computer or device changes. Many ISP's use dynamic
IP addressing for consumer DSL offerings.
I'm a residential DSL customer, what firewall
solution can I use that isn't expensive or complicated?
The easiest and least expensive firewall solutions are personal
firewall's, which are programs that install on your computer. The
two most popular are Norton Internet Security 2003 (www.symantec.com)
and ZoneAlarm (www.zonelabs.com).
I'm a small business with multiple computers
connected to my Ethernet DSL modem and I want serious protection
for the network. What are my firewall options?
You can choose from two firewall solutions: set up a proxy server
on a computer connected to the DSL modem or use a firewall appliance.
You can choose from a variety of proxy server programs.
A firewall appliance is an external box that uses stateful packet
inspection. It sits between you DSL modem and your LAN. A firewall
appliance costs around $500. The two leading firewall appliance
products are the SonicWALL SOHO (www.sonicwall.com) and the
