What
is ADSL?
ADSL
("Asymmetric Digital Subscriber Line")
is a technology used to deliver high-rate
digital data over existing ordinary phone-lines.
This is often referred to as "Broadband".
It works by splitting your existing telephone
line signal into two, one for voice and the
other for data. ADSL enables the simultaneous
use of normal telephone services and high-speed
internet access. So, no more waiting to use
the phone while the computer is on-line.
The
ADSL technology at Norfolk Telecom can work
at up to 20Mbps download but since Norfolk
doesn't have access to the unparallelled speeds
provided by fibre we limit customer rates
so that everyone gets a fair share. The services
on Norfolk Island at the moment are running
at speeds from 256Kbps up to 512Kbps for download
(approx. 16 times faster than a dial up modem)
with upload speeds between 64Kbps and 256Kbps.
This is why it is "asymmetric",
because the download speed is different to
the upload speed.
What
do I need to get online?
A
Norfolk Telecom Telephone Line
Also,
it has to be within 3.5 to 4.5 kilometres
of the telephone exchange or one of our Remote
DSLAM sites (now located at Saties Corner,
Rocky Point Rd & Anson Bay). Your phone
line must pass a line qualification test before
installation can go ahead.
An
ADSL Modem or Router
An
ADSL modem is a device which maintains the
connection to the Internet for you. Most routers
have an Ethernet connection to your local
area network and act as a gateway, DNS, DHCP
and firewall service. Computer enthusiasts
or businesses can use a router to connect
multiple computers to the Internet without
the need for connection sharing software such
as Microsoft Internet Connection Sharing.
Norfolk
Telecom can supply you with a selection of
leased modem/routers to suit your needs as
part of your ADSL service agreement. One of
our fully qualified technicians will come
and install it for you.
A
PC
Well
that's pretty obvious, but what you will need
in your PC is a working Ethernet or USB interface
to connect to the ADSL modem/router. If you
have a laptop that has inbuilt wireless then
you'll probably want one of our wireless modems,
no more annoying cables for you!
What
are the advantages and disadvantages of ADSL?
Advantages
-
High speed “always
on” connection
- 16
times the speed of a dial-up modem
- Requires
only one phone line (able to be on-line
and use the telephone at the same time)
- Multiple
PCs able to connect to modem/router
- Simple
setup for business networks, no extra hardware
needed
- Modem
operates as a firewall, protecting your
network
- Charged
by data traffic not by time on-line
Disadvantages
- Possible
teething problems for inexperienced computer
users
- Possible
addiction to the Internet

What
does it cost?
ADSL
services are provided with a number of rate
plans starting from just $30 per month for
250 Megabytes of data and extending up to
$150 per month for 2 Gigabytes of data. Email
through our services is free as well as browsing
on our local websites and the hidden stuff
like "DNS" (the internet phone book
service).
We
do put a limit on data in each rate plan but
we charge for extra traffic rather than limiting
your service. We mail out a weekly summary
and a monthly total of your usage so you can
keep track of your usage and you can change
your plan for the next month onwards free
of charge if you find you are using more (or
less) than you thought you would. So there's
no problems starting out small and adjusting
your plan to suit as you go and there are
benefits for the bigger users as the more
you use the less we charge overall.

plans with relevant charges. The full ISP
