In my house the phone wires come into the basement (from the externally-mounted demarcation box) to a junction block that looks like this one:
But the block is of some composite material and there is no obvious connection from either wire terminal to that centre screw. So what the heck's the point of grounding it?
I'd like to remove, or at least relocate, this block and modernize the phone cabling.Are devices like this still current? If not, what's the "current" correct replacement device?
Thanks,
Chip C Toronto
