So, call me a n00bl3t, but I'm having difficulty with beige boxing. I built my box to spec, and I went out to practice on my own TNI. Apparently, when I had the phones rewired some years ago, they put a newer TNI on the house where the terminals aren't accessible by taking off the nut. They replaced the standard 3/8" nut with a keyed Torx screw that requires a special bit to open. They're called Tamper-Proof Torx, and the last time I had to take one off, I used a fucking Dremel to cut it off. Should I expect most TNI's to be bolted this way, or should some older homes still have the 3/8" bolt hiding the terminals?
