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.
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?
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.
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?
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.
