We keep an older phone (Trimline Princess I think it was called). It plugs into the wall with an RJ-11 jack. Why keep it? when the power fails, and the cell towers are jammed to capacity, the plug in phones will still work at their power comes through the wires from the phone company.
Note that the phone system even with the wired phones only had capacity for ⅓ of the people to talk. It has never been possible for ½ of the company to pick up the phone and talk to the other half. Note sure what the status is for Cellular phones.
Other fact, in the not too distant past, the 404 area code for Atlanta Georgia was the world’s largest toll free calling area. They split in into 404 and 770. It is still the world’s largest toll free calling area.
Also: Why was the govt so concerned about the breakup of AT&T and forcing them to let other companies use their lines? Scattered across the country are hardened communication switching sites that were designed to provide communications in the event of war. When AT&T broke up the question was who would be responsible for those sites?
Further side note – Go research the “secret” of The Greenbrier in W Virginia. Highly guarded secret until the 90s when a newspaper broke the story.
