We use 12 and 48 port VDSLAM's similar to that at some of our remote
locations, and we do generally line power those.
But before those came on the market we were putting out remote

All the conventional telcos are far more focused on keeping voice

All true telco equipment is powered by batteries. Commerical power or
generators just recharge the batteries. No switch over when commerical
power is lost. Except when the generators(where equiped) switch over to
recharge the batteries.

How distributed is the power on a typical HFC system in practice?
