Never had problems until lately with 2 surge damaged phone systems (Lightning), Both with Comcast dial tone feeding 4 lines.
What do you do to protect the system other than the standard C.O. line protectors? Comcast does not provide any protection on the dial tone. There is a dependable UPS on the power to the system, and secondary protection(sneak fuses) on the C.O. lines from before the Comcast install with no problem. Could a bad or no ground at the Comcast primary connection be the fault? It did not look good when I checked it. Loose and corroded.
Thank You for any help
