Broadband DSL FAQ
ADSL, also known as Asymmetric Digital Subscriber Line is a broadband service that utilises existing copper telephones lines to send and receive data at speeds that far exceed traditional dial-up modems.
- Great Speed – It is up to 35 times faster than traditional dial-up internet. This means you surf the web, download email, music, videos and other files very quickly.
- Always On Internet – ADSL gives you a permanent internet connection, meaning when you need to use the internet it will be immediately available. No more waiting for your model to dial up.
- Make Calls Anytime – ADSL allows you to use your phone to make calls whilst using the internet. You no longer have to disconnect your modem to make a phone call.
Data is transmitted on a digital frequency, which sets it apart from the analogue signals telephones and fax machines use. Due to the ADSL signal is operating on a different frequency, the telephone can be used normally, even when surfing the Web with ADSL service. You will require a DSL filters on each phone or fax line, to “filter out” remove any noise on the line that might be generated by the ADSL service.
ZettaNet cannot guarantee that you will receive a certain speed. That is why we specify “Up to”. Speed is typically affected by:
- Distance from the telephone exchange.
- The number and type of other services on the line.
- Your phone line quality of the copper pair between the exchange and the your premises .
- Your hardware (specifically modem).
- The capacity and current load of the server or website you are accessing.
A majority of customers will sync in excess of 6Mpbs with some reaching up to 15Mbps and a small minority close to 20Mbps.
There are some technical differences between both technologies. From a customer perspective ADSL provides downloads speed up to 8Mbps. ADSL2+ provides speeds up to 24Mbps.
Our Broadband DSL services are delivered over copper telephony line via the Telstra, Optus or AAPT Wholesale Broadband Network.
