1. What is ADSL?
    Short for Asymmetric Digital Subscriber Line, ADSL technology, utilises unused frequency on existing telephone lines to send Data at high speeds. Conveniently ADSL signal doesn't interfere traditional voice, allowing the two to run concurrently on the same telephone line. To support ADSL the local telephone exchange must be "ADSL enabled", with special equipment called a DSLAM, which communicates with an ADSL modem installed on the local premises. To find out if your line connects to an ADSL enabled exchange, go to the Call Australia website homepage and click on 'Broadband' then 'How To Apply'

  3. What do I need to get ADSL?
    You'll need a copper phone line, which is within 3.5km of an ADSL enabled Telephone exchange. The line must not be fibre-optic cable (as sometimes provided by Optus) To find out if your line connects to an ADSL enabled exchange, go to the Call Australia website homepage and click on 'Broadband' then 'How To Apply'

  9. Can I use a 56k (analogue) modem on the same line as DSL?
    A DSL modem is required to access broadband speeds. A 56k Analogue modem can run on the voice channel, however the maximum speed for the analogue modem will remain the same as before. Note: A filter or splitter is required so the DSL signal doesn't interfere with the analogue modem.

  11. Do I need an active phone line to get ADSL?
    Yes. You need an active phone number so we determine if your line is within reach of a DSL-enabled exchange. (Also see 7)

  13. Can I have my ADSL Installed on a new line?
    Yes, once it is confirmed you are within reach of the DSL enabled exchange a new line can be installed. However, Call Australia cannot guarantee the new phone line will work for DSL as we can only check for DSL compatibility once the line installation is complete.

  15. Can I make a phone call or use the fax whilst using the Internet?
    Yes. A filter or splitter is required to ensure the phone or DSL quality is the best.

  17. I've got a back-to-base alarm. Can I still use it?
    This varies between alarm systems. Contact you're Alarm provider to check if your system is compatible with DSL.

  25. What is "Dial up PPP"?
    • Software, which captures and communicates your username & password for Authentication.
    • PPPoA & PPPoE versions of this software.

  27. What is a Filter?
    Also know as a Microfilter or inline filter. A Filter is a matchbox sized adapter placed just in front of phones & faxes. The filter blocks the ADSL signal, allowing only the voice signal to pass through. Without a filter a buzzing sound may be heard on the phone line.

  29. What is a Microfilter?
    See 14 "What is a Filter"

  31. What is an Inline filter?
    See 14 "What is a Filter"

  33. What is a Central filter?
    A central filter splits the ADSL and Voice signals to apart, presenting ADSL on one port & voice on another. Central filters are commonly used in a study environment, where an ADSL modem and telephone will share the same phone extension. 18. What is a Splitter? Similar to a Central filter, a splitter is hardwired at the access point Requiring professional installation a splitter, splits It physically splits the incoming line in two and places a filter on the phone part. No more filtering equipment is required. Strongly recommended if you are running more than 4 non-DSL devices (eg one fax, one dialup modem, one kitchen phone and one next to the computer).

  35. What's an NIC and do I need one?
    Network Interface Card, It is installed in your computer and has an Ethernet port in it. You do not need one if you plan to run a USB modem. If you do not already have a NIC installed and are planning to purchase one, ensure it's a 10/100 version.

  39. What's an IP and do I have one?
    Internet Protocol. IP generally refers to an address assigned to your computer, called an "IP Address". When logging onto the Internet your computer or modem (depending on your set-up) is assigned an IP address. An IP address is the virtual equivalent of a street address, uniquely identifying your computer on a network, or the Internet. "Static IP addressing" occurs when you are assigned an IP address and it remains, regardless of whether you restart your computer or not. Call Australia does not supply static IP addresses.

  41. What is a "Dynamic IP address"?
    When logging onto the Internet your computer or modem (depending on your set-up) is assigned an IP address from a range of addresses known as a pool. When you log off or disconnect this IP address returns to the pool, ready to be assigned to another user. The next time you logon a different IP address is assigned. This is known as "Dynamic IP Addressing".

  43. What is a "Static IP address"?
    When a users computer or modem, is assigned the same IP Address each time it logs onto the internet, this is known as a static IP address.

  45. What's a "port" and why do they have different numbers?
    While an IP address is used to identify a computer on a network or the Internet. A port is used to identify an application on that computer. Example: Outgoing mail is sent to port 25. Incoming mail is sent to port 110 & www requests to port 80 A listing of common ports is available here.
