BT66 Junction box

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?

Re: BT66 Junction box

You don't want to run extensions from the junction box, especially not star-wired. They should be filtered at the master socket first before running off to an extension and be daisy-chained.

And you don't want an external NTE.

Re: BT66 Junction box

So the other half of the houses on the estate have star wired set ups?

Re: BT66 Junction box

Looking at your 1st picture there is only 1 cable entering the house, so I can't be sure. But from your description that is what you are suggesting you want to do. Extensions should be run from the master socket and the master socket should have the external cable connected to it and nowhere else.

Re: BT66 Junction box

So you're saying, I have to start the extension cable from the master socket which is upstairs to my kitchen?

 

Rather than having a BT66 junction box?

Yes. Rather than introduce a bridge-tap.

Do you have Infinity?

Re: BT66 Junction box

Is it FTTC, which is susceptible to bridge taps, or FTTP, which isn't?

Can't believe that external cable cover still has the old BT logo on it. That means it is over 22 years old. Must have been a significant over-order back in 1991 for them to still have stock now.

Re: BT66 Junction box

What type of wiring do I use from the master socket terminals to the kitchen? Then I fit a extension ssocket at the end of the wiring.
