Hello....I have cellular (Verizon) and an old POTS module which is now giving me constant "Phone Line Failure" connection and reconnection errors after switching to FIOS. Prior to my new modem (connects at ONC)...no phone line to modem, I was successfully using my line seizure (RJ 31X) wired to the GC2 panel (POTS and line connection).

Tried disabling Q63 but still getting the errors. Any ideas?

I'm considering dumping the phone line backup, removing the POTS module and just going with GO Bridge Broadband backup (alarm.com). I have a TS1 panel so I must have the 900 MHZ board to power it.

Any help or thoughts would be appreciated.
