The low voltage DC power at 48 volt is made available on copper pair, in case of POTS. The actual current you can draw is few hundred milliamperes before the Central Office or telephone exchange fuse gets blown.

Actually, I've talked about both!
POTS has battery-backup-power at the phone-co office (AIUI).
FiOS has a battery-backup on my wall where the installer hooked the
phone-input (to my apt.) to it.
I haven't actually had to test the FiOS backup system out yet, though,
although I do have experience over the years with POTS being available
during power outages.

She wasn't talking about POTS, but about FiOS.
