Configuration of digital program-controlled telephone exchange (various schematic diagrams) (Word format)
The invention of the telegraph sent the information that people wanted to transmit to the distance at a speed of 300000 kilometers per second. This is an epoch-making initiative in the history of human information. But over time, people were a little dissatisfied. Because to send a telegram, you need to draft the telegram first, then translate it into code and send it to the telegraph operator; After receiving the message, the operator of the other side must first translate the code into text, and then deliver it to the receiver. This is not only a lot of procedures, but also a lack of timely two-way information exchange; It will take a long time to get a call back from the other party. People's dissatisfaction with the telegraph prompted scientists to start a new exploration. Hughes was the first person who proposed the idea of transmitting information by microphone relay over a long distance. Although this method is not practical, the name Hughes chose for this way of communication, "telephone", has been used up to now. After the 1830s, people began to explore the method of transmitting music and voice with electromagnetic phenomena, among which Bell and Gray were the most successful.
