Those are for cell phones, that has nothing to do with landlines, cable TV, or your internet. So if you're worried about your box so much for a landline, you shouldn't have broadband internet or cable since those all are in the same boxes.I don't how the security of landlines boxes are set up where you're at but down here, they seem to value phone towers more than they do with landlines boxes. There's always a security outpost near phone towers but none for landlines.
