When I redid the various extensions at home  Skruntie I used 0.5 2 pair -  although I only connected 1 pair into the system, leaving the other pair redundant :y

For a single line you need 1 pair plus a single ringing line, which you can often get away without.

Technically, you are supposed to use a pair for speech, and the orange wire for ringing, optionally white orange for Earth recall. Green pair for data on older pbx (BT Norstar and similar use orange pair for data and speech).

So most domestic houses, blue pair and the Orange wire in use.

Since the advent of ADSL, there are some performance gains to be had under some circumstances by not using the ringing circuit. This is pretty much what the i-plate does. This may stop some phones, particularly older ones, from ringing though.

Whatever wires you need/use, its wired as follows

1 - Green/White
2 - Blue/White
3 - Orange/White
4 - White/Orange
5 - White/Blue
6 - White/Green

As said, in domestic house, you will definately need 2 and 5 connected, possibly 3.

Wish the breakwit who wired our house had observed that. Current wired with 3 wires - one from EACH pair. >:(

Needless to say the ADSL is filtered at the master socket or it'd be radiating everywhere.

I did get half way round the house correcting it once, before I had a sense of humour failure and put it all back how it was. >:(

Even if filtered at master, its likely you'll still be suffering.  Might be worth fixing it, then seeing if your sync rate improves.

Many thanks eveyone.

Am having a new line from the pole outside fitted tomorrow as I was told I wasnt on a line at the exchange.

Might just leave  the master socket to do all the work as I have twin DECT phones, So tha main base/phone and Modem/rputer can plug into the master.  I was because I was considering a new pair of phones that I consodered the 2nd socket and I could add the new phones as I realised they were all Gap xompatible.
