Hi:
Where do landline telephone systems get their electricity from? During power outages, the landlines continue to function. Does the telephone exchange have it's own power generator? If so, what is the fuel?
Thanks,
Stamford

Things that make you wonder. Onan makes huge generators. Ours is a huge natural gas powered unit that makes a ton of noise. The regular power comes from a rectifier that charges 26 storage batteries (approximately, depending on the end cell arrangement). AC is generated by an inverter if needed so a Central Office can float on battery power for some number of hours. https://now.cumminspower.com/content/YellowPages?gclid=CPqYpvOa8LACFWkCQAod5zzDvw Carl

Central Offices & POPs have a generator (natural gas or diesel), transfer switches, rectifiers, inverters and battery strings. All items work together to ensure that all of the telephone equipment will have a constant supply of electricity in the event of a commercial power failure.
