Verizon Telephone Ringer ISSUE (land line)

Last mile. between your DEMARC and their SLIC where up to 16 lines are multiplexed to a single pair o the C. O. More lines, if it s Fiber Optic to the C.O, They work from the SLIc towards your house, looking for problems.

FINAL UPDATE:

On Wednesday, 2 Verizon service men showed up. They did some testing at the pole first, and concluded the problem is in the house.

Note: The previous owner of this house had two phone lines coming in from the pole, and several lines inside the house.

The service men rewired the main jack, and removed the MOVs surge protectors (I installed years ago). They ran more ringing tests and since then, the telephone ALWAYS rings when someone calls.

I tested the MOV surge protectors and they "clamp" at 250 volts. Even though they seem to be OK, I am going to order new ones.

FYI: Ringing voltage is about 90VAC (20HZ) unloaded (no devices on line). This is RMS voltage with a PEAK voltage around 127VAC.

Thanks again to everyone, John

Is your phone connected to your modem or are you still on ADSL?

I installed MOVs on my phone line years ago, they failed when there was a nearby lightning strike (I suppose they did their work). I had to remove them to get the line working again (which was ISDN at that time, so 90V DC all the time) and ever since then the two defective MOVs have been laying in a corner of my electronics work desk waiting for me to get new ones.... never got around to ordering some, and the local electronics store where I bought them has long been closed down.

It may be that they were the cause, but of course it may just as well have been a bad contact that they fixed by fiddling with it.
