How It All Began

• An accident gives Alexander Graham Bell his idea for the telephone

• Alexander Graham Bell patents the electric telephone in 1876

• Lawsuits were filed by various individuals, and Bell’s claim to being the inventor of the first telephone had to be defended in court some 600 times

Switchboard Operators

Page 4: The Evolution of the Telephone

Switchboard Operators

• The first telephone operators were under-trained, unsupervised telegraph boys but were soon replaced by young women who proved to be more pleasant and reliable

• The ever increasing number of callers soon transformed the profession. By 1946, nearly a quarter-million switchboard operators were employed by AT&T

• In 1921, Omaha, Nebraska opened the first all-automatic exchange

• Today there are no telephones served by manual exchanges in the United States. All telephone subscribers are served by automatic exchanges run by computers, which perform the functions of the human operator

How They Work

• Sound waves are converted into electrical signals, and electrical signals into sound waves

• The telephone required the simultaneous invention of the microphone, signal amplifiers and speaker

• Parts:– Transmitter (microphone)– Receiver (speaker)– Dial (pulse or tone)– Alerter/Ringer– Antisidetone network
