Is that way popular in the UK? I think it is quite an expensive way, no?
As ADSL has only just arrived in my area, I wouldn't like to guess how many people will go this route. I don't doubt that individual plug-in filters will probably be more popular (at least to begin with) among the less technically minded.

In the case I mentioned above, the line enters the front of the house and the computer is at the back. At the moment the guy is using rather tatty extension cords run around the edges of carpets etc. to get the phone line back there, so it needs replacing anyway. He decided he'd rather have it done with a single splitter/filter at the demarc. I can certainly see this as a better way for anyone with multiple telephones all around the house.

As Jim mentioned for the U.S., the premises wiring is the homeowener's responsibility here these days as well. Our standard modern network interface is the NTE5:

The removable panel at the bottom is where the subscriber terminates his own extension wiring.

We can get an ADSL filter which takes the place of that lower connection panel and provides a standard BT phone jack (filtered) and an RJ45-type for ADSL.

Click here for an example.

Curiously, the genuine BT replacement only provides an unfiltered feed on the front jack itself, with just filtered terminals for voice available for connection to extension wiring. Revised versions are available which also provide unfiltered terminals for running ADSL extensions. (Of course, with the genuine BT replacement you could still tap the incoming line terminals inside the demarc to run unfiltered extensions, although officially this is verboten!)

I'll just be running CAT5 cable from the demarc to the rear of the house, where a 2-gang voice/ADSL jack will be installed. White/blue pair will be filtered voice line, orange/white will have one line in use for the bell feed (as is standard on regular phone wiring here), then I'll put the unfiltered line on the white/green pair to the RJ45.

I'm actually going out later today to do the install, although his ADSL service isn't due to be turned on until the end of the week.

It's supposed to be a 1Mbit/sec connection, but at 5 miles as the wire runs from the C.O. via some rather dodgy cabinet splices we'll just have to wait and see...... [Linked Image]
