Microfilters are phone adapters which must be plugged into all active telephone sockets on your ADSL line which are used for plugging in telephony equipment (such as telephones, fax machines, PCs & Sky Digiboxes). You'll need one microfilter per socket you wish to connect your telephony devices to. This easy-to-install device ensures clean separation of data signals from voice signals. Without microfilters, you may experience noise on the line when you make or receive a telephone call, or may experience connection problems with your BT Broadband service, including low speeds & disconnections. Each microfilter has a socket for a standard telephone plug (like those on the end of equipment such as telephones, fax machines & analogue modems) & a socket for a broadband (ADSL) modem. A maximum of four microfilters can be used on an ADSL line. This is the recommended maximum number of items of telephony equipment you can plug into a standard voice line, (known as the maximum Ringing Equivalent Number
