telephone+exchange

In 1888 the telephone exchange was brought to Geelong, Australia. At the time Geelong was still a town but was very up-and-coming technology coming into the picture of the town a lot more making it a nicer place to live. The telephone exchange works by people at the end of the line connecting and disconnecting the cords (like shown in the picture below). Prior to the telephone, electrical switches were used to switch telegraph line. The telephone exchange was invented by Tivadar Puskás in 1877. Significant Event or Major Change
