Blue to two, orange to five, green to three, and brown...... don't bother.

Thanks.

Cheers!

Just as a follow-up to this, I got my IDC tool and made the connections as suggested above and unfortunately it hasn't worked. I don't seem to have done any damage, the DSL and phone is fine when used from the master socket or test socket, but there's no dialtone on any extensions still.

The only thing I wasn't able to do is to get into the other 2 extensions to check that the wiring colour scheme matches the one I was able to get in to, I can only assume that it doesn't since I'm pretty sure I've done the wiring correctly at the master faceplate.

The 2 extensions I refer to are part of big multi-plates with 2x satellite TV, aerial and radio on them so I'm really not comfortable taking them off the walls.

I think I'll do better to get a professional in at this stage. But still, thanks to everyone who replied to this thread.

Running the phone so close to all this and the mains probably too, is not great, i.e. the chance for this introducing noise is much greater.

I'd suggest if looking for someone to do this, make sure they know about things like the I-Plate and ring wire, if so then a good chance they may know some of the better practices. Too many people claim to do phone wiring, but do things like use sub standard cable, or use the wrong wires

Hi
I am in the very same situation - just moved into a new build where the master socket is also in the utility cupboard, and I also have other extension sockets around the apartment. The developer told me the very same thing, so I asked the BT engineer to connect the extensions when he came to connect my master socket, but he refused to do the extensions, saying i would have to pay another 125 for a different engineer to come out.

anyway, just wanted to know if you managed to get this working on your own, or if you resorted to calling BT. I am hesitant to even try because I can't follow any of the diagrams online and am really far from handy...

If anyone else can help, it'd be really appreciated. Also, can I hire any electrician to do this, or do i HAVE to use BT??

Thanks in advance -

BT are only responsible for the wiring up to the master socket from the exchange. You can do what you like with the extensions.

Anyone can connect extensions from the master socket. Dosnt need to be an electrician, though someone with an understanding of telephone wiring maybe helpfull

hi could please help me - i had a new BT Openreach master socket face plated fitted by bt engineer (replaced from old )bt engineer disconnected extension cable which was originally connected to master socket. extension cable have blue & blue white, orange and orange white and on the face place nothing connected to pin 5 pin 3 pin2 could pls advise me what colour cable should i connect to what pin

thanks
tony

You should only need to have the blue/white striped wire connected to IDC2 and the while/blue striped wire connected to IDC5.

That assumes the extension socket(s) was (were) wired correctly, in the first place. To be absolutely sure, check the colours of the wires at the extension socket(s).

There may well have been a valid reason why the engineer left the existing extension dis. Fault on the extension wiring going away, etc, etc.
