Which of course also goes out if the power fails, perhaps not as quickly as a poorly constructed POTS system but it will. Various emergency sitatuations (hurricanes etc.) have demonstrated this repeatedly.
That surprises me. In Missouri, analog (a.k.a. B1) phone lines are considered "life saving devices" and have (had?) mandates to be available for service even when the power is out.
This is one of the reasons that TelCo equipment had such massive battery backups.
I expect that a true analog (B1) phone line should stay in service even without power.
I've also seen a number of VoIP offerings that include a battery backup both in the ATA and various equipment along the aggregation path for this very reason.
