      Confusing wire colours on RJ45 extension to VDSL faceplate?

      I plan to add a VDSL faceplate to my NTE5 master socket then hardwire an RJ45 extension socket for my Sky hub. I am just a little confused about wire colours and hoping some kind person can clarify for me so I can wire correctly.

      BT convention dictates that the incoming line white wire connects to the A terminal which connects with internal white/blue wire to extension pin 5. The orange wire connects to terminal B which connects with internal blue/white wire to extension pin 2.

      Instructions for the RJ45 extension say the blue wire goes from unfiltered terminal A to RJ45 terminal 4, and the white/blue wire goes from terminal B to RJ45 terminal 5. In other words the blue and white wires are transposed on A & B when compared with the telephone wiring.

      Can anyone confirm whether this is right or have I misunderstood something somewhere?

      What extension kit are you using? Polarity doesn't matter in any case.

      I haven't bought it yet but the instructions are for this one. I thought that with 50v across the terminals that the polarity would need to be right.

      You must be right as these instructions for the same kit are exactly opposite from what it's manual says. I will meter through from A & B to pins 4 & 5 on the faceplate RJ45 socket and wire the extension the same so it should be right!
