BT66 Junction box

[#1]

Hi all!
After driving around my 'currently' building housing estate, I found that the houses just built a few months ago have a BT66 junction box outside beside the front door.(example)
Mine is just a plastic cover with the main line entering the house and going to the master socket like here
The reason I would like a junction box as above is so then I can easily put in telephone extensions from the junction box to the kitchen, as my sky box needs a telephone line connected.  It would be a pain to drag a cable from upstairs to the kitchen downstairs, whereas where the cable enters is just a few metres away from the kitchen.
Also what are my options? Can easily fit a BT66 or even an external NTE?

Ask your present supplier as it is all down to the company who provide the phone line

Sounds almost like you're trying to create some sort of notoriously troublesome "star" wiring arrangement, with each socket independently wired to the incoming line, which is not good for DSL.
I seem to be stuck with an outside BT66 and star wiring. Each time the phone line has died, an openreach engineer re-does all the connections in the BT66 until they manage to get it working again. Apparently replacing this dreadful setup with a modern master socket is just not going to be done for a voice fault. And the most recent time it was fixed, the fix was disconnecting one of the sockets, so then I had to complain about the £129.99 charge for the ridiculously-named "engineer home improvement service", but I suppose that's the fun you get if you don't have a test socket.
