2. What is ADSL?
ADSL stands for Asymmetric Digital Subscriber Line. It is technology that allows copper
telephone pairs to be used to provide a broadband connection. It provides an ‘always-on’
Internet connection that is automatically established once the PC and ADSL modem/router are
switched on.

5. Do I need a separate line for ADSL?
No. ADSL can run on your existing landline provided that your line is capable of supporting
ADSL and there are no incompatible products or services already on your line.

6. Can I use both phone and ADSL together?
Yes. ADSL uses a different set of frequencies to transfer data, it does not interfere with voice
telephone calls. You can also use Credit Card machines, fax machines, an answering machine, and
other EMI devices in parallel. If you use the line for both data and voice you will need a microfilter.

7. What is a Microfilter? And do I need one?
If your business uses the same line for voice and data then you need to separate out these
signals by using a filter. The filter has one output for your telephone and one or more for the
ADSL router, which connects to your computer. You can use multiple devices like a fax
machine, credit card machines, and other devices such as Inter-flora services in parallel.

8. What is download/upload?
When the information flows from a web-page or a site to your PC you are “downloading”.
When you send information e.g. request for a web-page, you are “uploading”

9. Why are the download/upload rates different?
ADSL is an asymmetric technology with different rates in “download” and “upload” directions.
This is because we download (browsing, downloading clips, music etc) much more than we
upload.
