There are still live copper pairs in cabled areas.If the original poster lives in a 'cabled' area, then the BT NTE will definitely be redundant.
Yes, but VM do not use any BT infrastructure in cabled areas.
Are you really sure about that ?It's in his own house, he can do whatever he wants with it!
So I buy a house and have VM install their cable services (including voice line over their own copper), and there's an old OpenReach box on the wall that the previous occupant had installed.
Are you seriously suggesting that I cannot touch the OpenReach box?
