There really shouldn't be a difference between the tower and the exchange, both need power to run and both are going to rely on modern data communication for anything not directly connected to the exchange. Cell phone power side at least makes sense, if you don't have any form of backup or off grid wattage yourself than getting power through the line is reasonably differentiating.
At least in my country, cell towers are numerous and get an equipment cabinet about the size of a fridge; telephone exchanges are one-per-city and the size of a small office building.
Much easier to provide a generator for the latter.
Yep, this was why as a kid we kept our landline even after we all got cellphones: Old-fashioned landlines were more likely to still work during a power outage.
