Pete in California wrote, regarding the recent article on POTS telephones:
“Remember too, that early telephones used much lower voltages than later equipment; 3VDC, to be exact. Those big, wooden wall phones had a compartment incorporated in them to house two large 1.5VDC batteries to allow users to talk to the central office operator. Ring voltage was provided by that crank on the side, which generated 90VAC at 30Hz. Remember those “Cox” gas planes you played with as a kid? Remember those big cylindrical batteries you started them with? Remember that they said “Telephone Battery” on them? That’s why. They were telephone batteries! To this day, the voltage used to talk between two phones is known as “talk battery.” Also to this day, the power used for POTS lines is actual battery power from the Central Office (CO). That’s why the old copper landline phones still worked sometimes for days after power failed. Modern POTS phones will work fine on 24VDC, which can be powered by two car batteries wired in series.
