Ok just so im clear on the back of the master socket there are 3 idc connectors numbers 2,3,5 (blue/white for 2, orange/white for 3 and white/blue for 5) the main adsl cable runs off the adsl port on the master socket. the connectors on the back are my starting point that go to the junction box ( i asume this cable will match the points on the master box 2,3,5) but on the junction box there numbered 1-4 each side with 8 slots again each side. So on one side of the junction there would be 3 wires and 6 on the other side as to were and how im un-clear about. the 2 cables that come out of the juntion will go to phone points were if need be i'll use filters if needed. thanks in advance for your input it's making things alittle clearer in my head!
