Switchboards, Old and New
Switchboards, Old and New
Assistir switchboards, old and new filme dublado TopFlix. Traces the development of voice switching methods from the first system that utilized the wires of a burglar alarm unit in Boston in 1877, to the "latest type" of switching in central offices, circa 1932. Along the way, we get the evolution of the Operator as well. Originally teenage boys were hired as operators, but it was quickly noted that they were not ideal due to being rambunctious and prone to pranks. Emma and her sister Stella Nutt were the first female operators, hired in 1878. They started a tradition that continued to the 1970s, when equal hiring practices made it possible for men to become operators as well, again.
