There was a phone came out here years ago used to 'short' the line every approx 20 minutes or so to charge an internal battery, played havoc with modems, dropping current connection. Wonder if you have something like that regularly sipping a charge off the line voltage?
Got a data recording whatsit you can hang off the line for a while?
Just because I'm paranoid doesn't mean they're not out to get me ;-)
But that's an interesting thought about a phone grabbing some "charge". We have six phones in the house, 4 different brands. I'll check that out. Thanks! ...Jim Thompson

Interesting, this was one of those posts where your first message didn't show on my news server. Censored posts, mysterious clicks on the phone line, maybe the goons are coming ...
Did you peek through the curtains whether that big black sedan with the tinted windows is still parked at the street corner?
Do you have an alarm system? If yes it might regularly check the phone line to see if it can get a dial tone.
This is their test desk. It probably is actually a program on their #5 ESS or whatever switch you are on, and it scans all the lines and connects the test equipment to all on-hook lines to check for anomalies like weak grounds. By analyzing this data with programs, they can detect trends, such as water getting into cables, that need immediate attention. It might not become evident from customer service requests until several weeks later.
Do you have voicemail sending VMWI signals? Googling finds that there are many proprietary signals that may be on a phone line in addition to the modern FSK data, including periodic zero voltage.

It might be those "science-fiction" analog line TDR - one dimensional radar?:
Time Domain Reflectometer (TDR):

If somebody dig/cut/short/water-short the analog phone-line(s) the telephone company can pinpoint how far down the line it happened - and when; with an accuracy of 1/2 hour?
-
Many bigger network switches has TDR-features on TP-cable for trouble- shooting purposes.
The reason - Gbit (and 10 Gbit) requires enormous amount of DSP - why use a little DSP on TDR?
Ok, is there a cable TV setup with optional pay TV? Many bill via a phone data transmission and might do similar line checks.
Other than that, plus in a POTS "phone-phone", zero electronics in there, and disconnect everything else. If it till does the pulsing then it has to be the line, and I'd be looking for that black sedan :-)
I plan on doing that, probably on a holiday weekend when I'm expecting no calls... like the upcoming memorial Day.
I certainly have my enemies. The local Letters-to-the-Editor are laced with "hate Jim" mail. All, of course, from useless slugs on society, aka Leftist Weenies ;-)
In a fit of pique I just registered "liberalsaredummies.com" ;-)
That ought to raise my enemies level :-) ...Jim Thompson

It does sound like a script running back at the CO. Given the migration to wireless, my bet is the POTS infrastructure is dying in-place. Maybe the script is load-testing the batteries, and what Jim's seeing is the "brownout" from batteries that are well past prime.?
