Like the phones that have a special plug and everything, the cord one still work when the electricity is out and they don’t seem to have batteries in there, so how and why do they still work

I worked for AT&T and can vouch that the Central Office has giant batteries that supply power (and usually a generator as well).
The batteries sit in giant barrels…they’re huge! I mostly did residential installs so didn’t get a chance to go into a CO often, but all the servers and battery vats and everything were very cool.
