Filtering - This is a brief note about filters and filtering.

The Broadband service is carried as a high-frequency signal on your ordinary phone line. This high-frequency signal is incompatible with your ordinary telephone and so a filter is required to keep the phone and Broadband signal apart.
It is possible to fit just one filter at the point where the phone line comes into your building, to do this you will need to have a NTE2000 Face Plate Splitter fitted. This may not be the best option for you if your computer is not near to the main phone point as all of your extensions will be filtered from this Broadband signal. However it is possible to rearrange your telephone sockets so that the BT master socket is located at your computer.

An alternative strategy is to use a filter at each point where a phone is connected. (Don't forget your satellite TV box or Alarm!). This is the most common setup.

If you live more than 3km from your local telephone exchange, the signal may be weak. Although the situation is rare, it is possible that the layout of the extension wiring within your house can degrade the signal even further. If you suspect that you may have this problem then you will need to optimise your wiring. The basic principle is to ensure that there is only one path for the Broadband signal, from your master socket to your modem. There should be no T or Y junctions on the way.

The best solution is to put your modem next to the master socket using the NTE2000 'Faceplate-Splitter'. This is an extra-high-performance Broadband filter designed to replace the lower half of the BT Master socket called an NTE5. As mentioned above if your BT master socket is not where your computer is we can rearrange your sockets to overcome this problem.
