You are likely already at the mercy of some local hut for your dialtone. Very few things home run to the co these days. It's unlikely any hut has more than 24 hours of battery.
I know this is true where FTTN overlays have been built. However, in the majority of California, at least, that is still more the exception than the rule and there is usually a Cat-3 Copper home-run for local dialtone.
[Frank Bulk] Here in the midwest each and every of the telcos that I've talked to or worked with feeds dialtone for their DSL customers from the same equipment that serves the DSL. To do otherwise would require a splitter shelf in each node.
I have talked to local techs that make the same trip each shift to fuel the generator during regular or minor power outages. Anything major, expect the service to die.
If nothing else, I expect various other components in the system (trunk overload, switch dialtone exhaustion, etc.) in anything major anyway.
However, 24 hours of dialtone after something happens still exceeds the average cablemodem duration after the power flickers.
[Frank Bulk] Some MSOs (including ourselves) have power systems (e.g. Alpha) in place throughout the plant to provide backup power for at least some time.
