The point is, that if outages are common there and your phone is not real POTS, then a power failure leaves you without any phone service. No mobile -> no alternative service.
In some places, cell towers have to have several days of backup power as does the entire infrastructure from the cell tower to the net backbone.
I know, I have installed them. However, with POTS, you have only a single site to keep powered for an entire city coverage. They are often connected to two main power lines. If both fail, there are huge batteries, and then, you can activate the generator. If this fails, you can still have brought an extra emergency backup generator, by contract with the power company. And the phones in the houses are all powered by the copper line coming from the exchange. That is, till they invented the cordless phone... -- Cheers / Saludos, Carlos E. R.
