Cut phone cable; help?

jamie2022021

Hello,
I’ve recently had someone in decorating and they’ve unfortunately cut the phone cable. 

I’ve pulled the cable through from the outside and I’m trying to reconnect. 

Which 2 colours come from the external cable and goes into the 2 x terminals (A and in the phone point (the box on the “internal” picture.  It used to go into a junction box which took the 6 cables and converted them into 2, but as I say, I don’t know which ones as I wasn’t.  

See image attached. It’s a very old 6 core cable and I have no idea which 2 are the active cables. 

Much appreciated if anyone knows the answer.

Is this on "your" side of the master socket or "BT's" side?

If its on your side, then phone cables only need numbers 2 and 5, legacy number 3 (bell ringer, often not needed these days) and number 4 is often connected (makes it look neat) but doesn't actually do anything.  Number 1 and 6 don't do anything either.

You might want to explain how those numbers relate to the colours of the wires that the OP has to deal with.

Orange and white should be the incoming BT pair.  Orange (0v) should go to B/2 and White (-48v) to A/5.  Generally though it should not matter which round they go. Note carefully the use of "should"

Should is right - when I had line problems the BT engineer went up the pole and swapped the lines to use the redundant pairs - and of course swapped them internally as well.

Why are you sorting it - the decorator should be fixing it seems as it was him that broke it

The “decorator” is actually a family friend and would probably manage to somehow make it worse.  

Thanks for everybody’s input. 

Yes, just to clarify the situation, which 2 (colours) of cables from the 6 core (external) go to the BT socket's AB (presently brown and blue as seen in “internal” side of the picture).

So I will remove the brown and blue from terminal A and B and try the orange and white as per molerat’s response.  Hopefully that will work and thanks again!   I will post an update once I’ve tried.
