I managed to crush my BT master socket over the week (moving a desk around the room) So I brought another master socket with a built in micro filter!!
Now my issue is I have 4 cables they are Orange, Black, White and Green and according to this diagram "bottom left" I connect red to 'A' and Green to 'B' but as you can see I have no Red??
I know I only need to connect 2 cables but can anyone confirm which 2 go to a & b please?
BTW I'm colour blind but I can still understand primary colours
Many thanks in advance!!
