Why do I need an ADSL Splitter? (or POTS filter)

 Apart from a modem/router the most important will be a POTS filter / ADSL Splitter.

This simple device filters certain “noise” from interfering on your ADSL line caused by your phone and vice versa. Without this device you will usually have to forfeit your ability to make normal phone calls and make use of the Internet freely and simultaneously without any interference.

You will need a POTS filter to be connected to each phone jack with a phone or fax machine present on the same physical line your ADSL modem/router connects to. They are usually in the sub R50 price range and are available at Telkom Direct shops and possibly other electronics related stores.
