digital converter box -- surprising performance

[Roger Kirk]

Regardless of what power supply outage protection might exist on the 
customer's premises; with Fios, does a comparable power 
uninterrupability exist from the CO all the way through the "last 1/4 
mile?"  Including cable repeaters, multiplexers, de-multiplexers, etc.

 From the CO's batteries to my phone, unbroken copper is still my best 
low-tech bet.
