On This Day in Telephone History March 27TH 1884 The First Successful Long Distance Conversation between Boston and New York.
It took place over a telephone circuit of two hard-drawn copper #12 wires. This line was regarded as an experiment, sponsored by the American Bell Company and built by companies along the route – a great part of the work being done by the Southern New England Telephone Company. The line worked for approximately 90 minutes before a cable failed at a river crossing. It took several months to solve as well as other technical difficulties. This was the first large-scale use of hard drawn copper wire. This initial work and the accumulated test records pointed the way to successful long distance service.
