    Could really do with some help please the telephone cable that comes into my house was put into the front door frame back in the day when i have had new door fitted they have disconnected the cable. I didnt think much about it as it wasnt urgent as the its a full renovation job however when i have come to reconnect it its not the same as modern cables. I was expecting to see 6 cables instead on have 7, solid green, solid black, solid orange, and 4 white cables with not colour banding so have no idea how to reconnect does anyone have a clue please?

    Black and green are a pair and orange and white ….there can be 3 extra yellow wires which are the support wires ….I would try black and green …

    Hi,

    Theoretically, where the cable comes into the house and up to the master socket is the property of BT / Openreach etc.
    And should not be touched! ;)

    Anyway, quick guide to telephone wiring here:

    If this is the master socket, you only need the orange and white connected :)
