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

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

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

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

8. What is download/upload?<br />
When the information flows from a web‐page or a site to your PC you are “downloading”.<br />
When you send information e.g. request for a web‐page, you are “uploading”<br />
[Back To Top]<br />
9. Why are the download/upload rates different?<br />
ADSL is an asymmetric technology with different rates in “download” and “upload” directions.<br />
This is because we download (browsing, downloading clips, music etc) much more than we<br />
upload.<br />
