<p>For my ISP, they maintain backup power for both DSL and POTS. I
suspect that for a lot of DSL that would hold true because it's
relatively easy for them to power since they already have the
battery backup requirements for POTS. The setup they have here is
a DSLAM and SIP->POTS termination in a pedestal with fiber
backhaul. They use the old copper that used to go back to the CO
to power the pedestal. </p>
