Broadband Questions

Answers

What is ADSL?
ADSL stands for Asymmetric Digital Subscriber Line. ADSL is a broadband technology designed for regular phone lines. Today, ADSL's primary use is for high-speed Internet connections. But ADSL has the potential to deliver video conferencing, television, video-on-demand, and other "cutting-edge" services.

What are the benefits of ADSL?
As well as the speed factor, ADSL is much more convenient than a dialup modem. ADSL modems are always connected to the network, meaning there is no "dial-up" involved, and you no longer pay a telephone call every time you use the Internet. Additionally, ADSL modems share a normal telephone line - you don't need a separate line for the modem. When you evaluate the cost of ADSL, remember to consider the savings on line rental and telephone calls compared to an older-style modem. And consider the convenience of having the Internet always at your fingertips - with no waiting 60 seconds for the old 33K or 56K modem to make connection.

What does Broadband mean?
Broadband is simply high-speed transmission. Its greatest benefit is that you can down-load (bring information off the Internet into your computer) at a much faster rate - up to 1.5 Mbps. Documents, free software, games, and more can all be down-loaded in one-twentieth the time of conventional modems - 56 Kbps. What makes it possible is an ATU Modem, which exploits the physical transmission capabilities of standard telephone lines, to achieve higher data transfer speeds.

How fast is ADSL compared to an ordinary modem?
Much faster: ADSL connections vary from 256K to 6000K, around 200 times faster than an ordinary 33K modem.

Do I need a special phone line to use an ADSL modem?
No, the vast majority of phone lines are suitable for ADSL modems. ADSL splits the phone line into two frequency ranges. Generally, the frequencies below 4 kHz are used for voice, whilst the range above 4 kHz is used for data. This allows the telephone to be used at the same time as the ADSL modem. More bandwidth is reserved for "receiving" data from the ADSL network as opposed to transmitting - hence the "Asymmetric" in ADSL.

Is ADSL available everywhere in Australia?
The wide-scale rollout of ADSL in Australia commenced in 1999. ADSL will be installed in hundreds of telephone exchanges across Australia; the entire process will take a few years to complete. Many areas are already ASDL equipped. By checking the ADSL Coverage Tool you can check if your number is available for ADSL. Simply enter your telephone number and it will identify whether ADSL is available in your area.

How is ADSL different to…….
The term "cable modem" is typically associated with Internet services delivered over Hybrid-Fibre-Coaxial networks, typically the same as used for Pay TV. ADSL is very different - we think it's vastly superior to cable modem technology. Here are some reasons:

  • The cable network is a "shared" network. This has implications for the speed and security of an Internet service. For example, only a limited amount of bandwidth is available per cable neighborhood. In general, the more people using cable Internet, the slower it becomes. Some users of cable networks overseas have reported transfer speeds worse than a 33K modem during busy times. In contrast, ADSL is a dedicated connection between the customer and the ADSL exchange ("DSLAM")
  • Competition amongst cable networks is extremely limited - they are controlled by a small number of powerful companies. The ADSL network is open to competition, and as such, consumers are likely to reap the benefit of lower prices and better choice.
  • ADSL is much better suited to business and corporate users. ADSL supports static IP addresses and network routing, unlike most cable Internet services. ADSL makes Virtual Private Networks affordable to many organisations for the first time. Branch offices can be linked at minimal cost. Using VPN software, staff with ADSL at home can login to the office network - at incredibly fast speeds.

What type of computer do I need?
Almost all computers (less than 3-4 years old) are suitable for ADSL. Please see our Support page for assistance on configuration and hardware requirements.

What is the different between ISDN and ADSL?
ISDN is a digital service supporting speeds of 64K and 128K in its basic configuration. ADSL is many times faster than ISDN, and for most Internet-related applications, ADSL is a better choice. ADSL is also significantly cheaper than ISDN when you do not have to pay for ISDN call rates.

That sounds great, how long does it take to get installed?
It usually takes between 10-20 working days from the time you order until the time installation is complete.
