Phone Lines...

[BuuBox]

I thought I'd ask here for a bit of help on the ol' phone line. Today I decided to climb under my house to see what the cause of some line noise was, and to my dismay, I encountered possible the worst wiring job in the history of home repairs to phone lines. It was split through a Telecom (!) box into three lines, two of which traveled 10 or so meters until nicely terminating in a pile of dirt, while the remaining one went to the point in my lounge, nicely split into the two other points, taped together with electrical tape. To top it off rather than cutting the line to size, meters was simply coiled over beams.

So, short version, I found the source of my line noise! I rewired the telephone points through the Telecom box with the help of a friend, however have one question to ask...The Telephone line has 4 wires: blue, white, red and black. It only had the blue and white wired up, and I did the same.

My question basically is: Are the red and black cables in a telephone line important? I intend to try and get ADSL (again), which was rejected initially for high line noise.

Thanks! Oh, I have no idea if this is the right forum, but since it's an automotive forum, didn't really seem to suit anywhere... ha.
