There was a time when the phone equipment was tightly controlled. There=20 was only one phone in the house and we were fortunate to have a line all=20 to ourselves. It was called a private line. I had a pair of wires in my basement workshop that led over to my=20 workbench from the telephone entry point. Taking no chances, a dpdt=20 knife switch made and broke the connection to an ancient handset. I=20 could now answer the phone from downstairs. Later I learned to dial=20 numbers with a wire in each hand. It helped that numbers were only 6=20 digits then. The last time I tried it pulse dialing from home it worked.=20 It ought to be easy with my Morse Code Paddle.
