While this is a safety issue, my cable company Cox Communications, brings up a RG-6 (from tap around 50 ft away) right into my house(that is before I got the Cox Phone NID installed outside my house). So shouldn't cable MSOs be blamed too for not grounding their services, especially because Cable services use the RG-6/59 power? Or do a lot of people have Cable NIDs for one service outside their houses?
