• It used to be that plugging in the coax connector of an old Telus modem (not the new ones) to the outside lines (say using a coax wall outlet that's still “live”) would take out the Coast Cable equipment of an entire block. I don't know exactly how this person's TV was connected, but it seems to me that it might have been connected to the system using its coax connector where it shouldn't have. Just because two things can be connected, doesn't mean it should :S – Patrick, VA7FI 2020/09/23 08:08
