ADSL2 Line Filtering and Why You Need It

In a typical home or business the phone line on which you have your ADSL installed is also used for one or more devices like phones and faxes. The problem with sharing the phone line is that phones and faxes interfere with your internet connection and cause it to disconnect regularly or not work at all! If you are having drop-out problems this is the cause 95% of the time.

Fortunately there is a solution to this, putting line filters on the phone line in front of phone devices will filter out the interference caused by them. This must be done carefully, as putting a filter in front of your modem will stop it working altogether. See the diagrams below. It is also important to note, that an ADSL2 filter is required for ADSL2 connections.
