Odd BT master socket install

[browners]

Manny moons ago when ADSL first became availabe I signed up immediatly. I had a BT Engineer install as at the time they insisted on it.

My line enters the front of my house into a junction box. This is then routed about 15-20 meters upstairs into the bedroom where a BT NTE adsl faceplat is installed.
I have now moved this into the attic as the office got turned into a nursery
Now from the main socket in the attic 2 wires return back down (the same cable, different pairs) to the junction box and are fed into the living room to 1 extention socket.

Basicaly I am asking would 15-20 meters up to the attic add much noise to my line. I assume it is good quality as BT installed it.

I was thinking of cutting this wire before the junction box and installing a brand new faceplate right where the line enters the house and plugging the router into that.

Current stats:

wether the extra cable makes any differance is hard to say, it depends on how much electrical noise there may be in your home, but if you can put the master socket directly on the incomming cable and put your router there (you can use your exsisting master and SSFP (the filter faceplate installed by BT) then it will do no harm.
I must point out that you are not supposed to alter this wiring before the master socket but lots of people do.

As Brian says it really depends on noise in the home, only way to find out is to try it!
