Call Panasonic or Rat Shack and ask.  Better yet, find one (your local
supplier will have one around, or won't get your order) in a working
state and bring your ammmmmmeter along.  Don't forget to plug in a
device to all the ports and take them off-hook -- they're
line-powered!

Now, if you could just use 48 Volts, you could snarf power from TPC
directly and not have any power costs :-)!
