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" or "Internet". It works by splitting your existing telephone line signal into two, Low frequency for voice and high frequency for data. ADSL enables the simultaneous use of normal telephone services and high-speed Internet access.
The ADSL technology at Norfolk Telecom can theoretically work at up to 20Mbps download but since Norfolk doesn't have access to the unparalleled speeds provided by fibre we limit customer rates so that everyone gets a fair share. The standard services on Norfolk Island at the moment are running at speeds from 3072Kbps up to 20Mbps for download with upload speeds 1024Kbps. 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
Or alternatively a bundled leased circuit, inquire at Telecom if you don't have a phone service. Our network has been configured to provide service wherever we have copper cable so it's available for everyone.
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.
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.
Well that's pretty obvious, but what you will need in your computer is a working Ethernet or Wireless interface to connect to the ADSL modem/router. If you have a Laptop/Tablet 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?
- High speed, high availability,“always on” connection
- 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
- Possible teething problems for inexperienced computer users
- Possible addiction to the Internet :-(
