How did a line finder actually work?
« on: June 26, 2016, 04:27:29 AM »
Hello Everyone,

In the step by step exchange, how did the line finder switch know to ratchet up and over to your line when one lifted the receiver to make a call? What if more than one subscriber picked up their calling receiver at the same time but both were connected to that line finder? What would happen then?
