British Telecom have come up with a device you just stick in your home phone jack that claims to decrease line noise and therefore (depending on how bad it was in the first place) increase the performance of your ADSL line.

Wonder if this is something Telecom will bring to market at all?

NZ Telecom dropped the 3 wire setup years ago, so is less relevant here. If you have 2 wire configuration, or a master splitter, then this device is not likely to make any difference.

3 wire configuration is still quite common in the UK, and is causing huge problems with ADSL. Here I think this is much less of a problem.

The old phones; them rotary dials & early touch tone phones needed 3 wires. 2 wires did the signalling (voice, off hook, dialling etc) and the 3rd wire called the bell wire is what made the phone ring. The phone line came in on 2 wire, went to the Master jack that then separated out the ring part onto the 3rd wire.

The modern phones don't need the bell wire, effectively it's like they have a "master jack" built in. So what happens to this third wire? Well, on most new phones you may notice they only have 2 wires in the phone cord, so this Bell wire goes nowhere.

What happens to a long wire going nowhere? It turns into an aerial.

The 3rd wire (the bell wire) which thankfully was abandoned here some years ago, has given the poms all manner of grief with ADSL.

Because its a single wire (that in most modern phones is not even connected or used) the wire ends up connected via the bell capacitor at the master jack and not connected to anything throughout the rest of the house wiring. The end effect is the bell wire acts as a long beverage antenna that couples all manner of LF and MF noise (which due to the large LF and MF transmitters in Europe/UK are a big problem) into the phones circuit via the bell capacitor, and stuffing up DSL performance.

My advise for those of us in NZ, upgrade your house wiring to 2wire or atleast remove the bell wire if you have 3wire sockets, if you have an old phone that wont ring with the bell wire missing then upgrade to 2wire. And finally install a central filter and use a dedicated line to your DSL modem.

Cheers for the informative posts people.
I had no idea there was a 2 wire/3 wire difference!

Cheers Cyril7, knew I could count on someone like you to jump in with a bit more of a technical answer than me!

The wire came about because the brits were too cheap to stuff a few more components into the phones to stop the bell in them dinging when other phones went on or off hook or dialed out, so the other phones shunt the bell wire as you lift them off hook or use an old rotary dial to stop it.

Problem is that it didnt work with push button pulse dialing phones so they had to do it anyway later on, but the cheapness has hung on thru legacy design requirements.

At least with BT its their problem to that master jack, and you can undo the top half of it yourself (legally) to do internal wiring, and in the process you isolate if from the jack on it so doing an isolation test for internal wiring is really easy, unlike here where the demarc is sealed with hard to find tri-wing screws and scotchlock connectors so most people need a tech in anycase.

My understanding is the new device is just a replacement adsl filter in the isolation plug, and another riniging capacitor.

Yes there is nothing new in this filter being fitted in the NTE-5 socket (isolating master socket) on the UK market, guess its just BT now sells them, but you have been able to get them from the likes of here for sometime.

I understand Telepermit here it trying to come up with a home owner installable central filter, but in the end to identify wire segments (ie identify the line from the first socket to the desired DSL socket site), understand whats happening and do the work is beyond probably 90% of most home owners so they still need a vist from a tech, which is the exact experience they found in UK when NTE-5 filter plates became available, they work if you just need to replace the front master faceplate with one with a filter in it, but if you need to couple the DSL line into the house wiring to take it to another site in the house most home owners got confused.
