Telecoms are generally required to continue non-voip land line service.
Nah, I can personally confirm that that’s no longer correct. My house didn’t have analog telephone service but still had a phone line running to it, until one day a few years ago I went outside and noticed that AT&T had taken the wire clear off the pole and left it laying in my yard. They clearly have no intention of ever providing such service in my area again, even if somebody wanted it.
