History Of Telecommunications
As it all began back in the prehistoric times, there has been methods of communications over large distances.

And for good reason the allowable words per minute increased. At the end of the telegraph, it was possible to have 72 transitions per minute.

It was established so that two people may talk over telephone wires, built from town to town. As the cables went through the town people who bought one of the machines was to connect theirs to the box outside of their houses (to the wires running through town.)
