I thought the Tellabs and Alcatel/Lucent ONT's provided a true 48 volt loop-start line.

But, I have yet to get my mitts on a technical manual for any of these units...

Does anybody feel like measuring the loop voltage and current on their FiOS ONT provided line? The results would be very interesting [this same subject keeps coming up on other forums as well].
