Manufacturer's Description
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 and 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 and disconnections.

Each microfilter has a socket for a standard telephone plug (like those on the end of equipment such as telephones, fax machines and analogue modems) and 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 - REN).

BT ADSL Boroadband Microfilter
I ordered this via Addonsworld and it arrived within 3-4 days. It is a Microfilter with a tail and sockets for both a telephone cable and modem; the one I recieved was branded as made by BT which I have used to plug my phone into. As a broadband virgin I have little experience of what to expect from this product but three weeks in it seems to work fine and there is no extra noise on my telephone line. I purchased it to use with a Netgear DG834G 54Mbps Wireless ADSL2+ Modem Firewall Router with 4-port 10/100 switch; this came with its own microfilter in the box and so far I have had no connection or service problems (broadband via Plusnet).

Approach with caution
We got 3 of these filters free with our AOL broadband connection. if they weren't free i would of sent them back, they seperate the 2 different lines fine there is no problem using the internet. The problem arises when u try to use the phone line, there is absolutly no filtering of the white noise so all the time that u are on the phone there is a fuzzy hissing sound in the background.

Watch the illustration
The above illustration is NOT the actual one you get. Other than that it is great.
