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

The issue is getting them out of their present locations. The used-equipment guys do not want to take on the liability of swinging a 30,000 + pound piece of equipment out of a third-floor via a hole-in-the-wall.
 
The displays are all high-res 1040p screens with some additional software-based enhancements. These units were in daily use until about mid-November.
 
At this point, we are speaking to several non-profits, and even a couple of embassies for smaller (and poorer) countries.

Good luck finding a new home for them. At one time I had to do certified destruction on a tractor trailer load of medical equipment. It arrived with a 1/4" hole drilled through the main circuit board of every unit. The amount of waste was disgusting. All we recovered were motors, displays and small parts. The circuit boards were required to be shipped to a gold processor to be burnt for recovery. I could see this, if the equipment had been recalled as defective, but 95% of it was less than two years old.

That would be great if it could be repurposed in that way.

*Is there software for testing an intermittent Arris SB6141 cable modem?*
(Costco item #774054)
 
As per suggestions by Jeff Liebermann, long ago I bought these college kids
in circa 2015 the $75 Costco Item Number #774054 Arris SB6141 modem, which
they've used in a series of college apartment situations until now.
 
Lately, their Comcast service has been flaky which the Comcast service
personnel determined today is not due to the Comcast service, but, that the
"signal is not getting out of the modem", intermittently.

The question for purposefully helpful adults on s.e.r is whether you know
of a good software test of a cable modem that appears to be intermittent.

Yes. Point your web browser to 192.168.100.1. The "Signal" page
displays the signal levels, error rate, etc.

Comcast no longer supports the SB6141 (16x4). The fashionable modem
for DOCSIS 3.0 is the SB6190 (32x8). For DOCSIS 3.0, the SB8200
(32x8). Both provide far more channels and bandwidth in both
directions. I've been replacing the SB6141 modems with these later
modems because the increase in the number of downstream channels or
the upgrade to DOCSIS 3.1 seem to cause some older modems to act
weird. I haven't bothered to investigate and just replace the modem
when someone complains. I also have to replace some wireless routers,
such as my former favorite Linksys EA2700, which will not work
reliably at speeds over about 100Mbits/sec.

If you want to waste your time with the SB6141, I have a few in my
palatial office that you can have for a nominal charge.
 
Also, I had some difficulties long ago with an SB6141 that turned to
the be a defective (probably overheated) power supply. You might try
a different 12V PS and see if that helps.

For DOCSIS 3.0, SB6190 (refurbished):

$60 plus tax and shipping.

I was thinking my Tripplet/B&K might have a relay function. It's a bench
multimeter. Would have to investigate.
