Where can I get a diagram/instructions on how to wire another telphone socket into an openreach master socket?

Question

I believe this type of connection can be carried out by the customer. The master socket enters in the living room and phone/internet connections are required in an office 20+ metres away.

Thanks

Yes, you are allowed to connect your extension wiring to the master jack.  In a modern installation the latter is an NTE5, which has a removable lower panel which plugs into the network interface.  When you pull out that panel, you'll see numbered connections on the back of it for your extension wiring.

For a basic line, you should connect the terminals at the master jack to the corresponding terminals of your extension jack using the following standard code:

2 - Blue/white

3 - Orange/white

4 - White/orange

5 - White/blue
