A "howler".

Which is indeed intended to be the most annoying possible noise
that can legally be sent over a telephone line... :-)

Older mechanical things no longer exist! Some of them also had
the nasty habit of locking out the line for a *long* time after
it was back onhook.

They all generate a log message of some kind, but anybody who
doesn't have those sent to the bit bucket deserves the piles
of paper/time wasted looking at them.

I don't think any of them would do that today, though of course
there could be.

They probably don't even remove the loop current, but just
monitor it. The only switch I have access to these days
restores my service in less than 2 seconds.

That's a *really good* idea!
