How does this old telephone ringer work?

A ring generator or ringing voltage generator is a device which outputs 20 cycle sinusoidal AC at up to 110 volts peak to power bells or annunciators in one or more telephone extensions. The output stops if a handset is taken off the hook. In terminology devised by phone phreaks, a ringing generator is a magenta box. The device can be used to simulate an incoming call by applying the AC ringing signal voltage to a POTS line to mak… WebNov 17, 2024 · In light of the fact that the phone line still works and when I go off-hook I get solid dial-tone, will increasing the voltage on the analog port affect the dial tone negatively?
