> FCC Part 68, what is the working voltage? Is there an operating range?

Read the "network - customer installation" standards of Committee T1, or
the
terminal standards of TIA.   For that matter, IEC Publication 950 will tell
you what the ringing voltages are.

All this stuff is public knowledge, and in exquisite detail for that
matter.

>>In order not to interfere with telco operations (dc line voltage and ring
voltage), most modems us MOVs rated at 240, 270 or 300 volts<<

Guess the Fine Art of doing your own research has died.
