OK. Just ruling out an impairment somewhere in the wiring. > With no handset connected, it sitting at 100VAC. I guess the > ring generator isn't working. If you're getting 100VAC, the ring generator *is* working. You should be seeing 100VAC for two seconds, then 0 (or minimal) AC voltage for 4 seconds, then 100 for 2, 0 for 4, etc. A ring cycle is six seconds - 2 on, 4 off. You've tried different sets?
