The origin of the telephone exchange: Who created this technology that changed the history of communications?
Telephone switches are the core components of telecommunications systems, both in the public switched telephone network (PSTN) and in large enterprises, and this technology has dramatically changed the way we communicate. Telephone exchanges enable telephone conversations between different users to be established smoothly, and therefore play an important role in the history of communications.
The evolution of telephone switches
From a historical perspective, the concept of telephone exchanges appeared in the 19th century, and there were signs of development even before early telephone equipment appeared. Early phones were only capable of communicating with a single device, and the problem was that the growing demands of users could not be met. As demand surged, it became clear that the model of single phone conversations could no longer be sustained.
“A telephone exchange is a new type of system that allows multiple users to communicate through a centralized telephone system.”
The Pioneers Behind Innovation
A notable pioneer was Tivadar Puskás of Hungary, who proposed the idea of telephone switching in 1877, and in the same year the Bell Telephone Company in the United States built the first experimental telephone exchange based on his idea. Germany later opened the world's first state-run telephone exchange that same year, and the United States' first commercial telephone exchange went into operation in New Haven, Connecticut in 1878. These innovative ideas marked the beginning of telephone switching technology.
Mode of operation of early telephone exchanges
Early telephone exchanges were mostly manually operated. When a user picked up the phone, they needed to seek the assistance of an operator to connect to the desired number. This pattern is prevalent in cities and is essential to provide reliable communications. In the case of manual service, a trained operator is required to insert the correct plug every time a call is answered.
"The limitations of manually operated telephone exchanges make the efficiency of calls dependent on human speed and accuracy."
The evolution of signaling and automation
As technology advanced, telephone exchanges began to move toward automation in the early 1900s. Almon Strowger patented the step switch in 1891, a technology that allowed telephone exchanges to automatically connect calls without human intervention. This means that users only need to dial a number and the system will be able to identify and connect to the desired call partner, greatly improving the convenience and efficiency of calls.
Modernization of telephone switching technology
In the 21st century, technology continued to develop, and digital signals and various new switching technologies replaced the older generation systems. Modern telephone switches can support higher call rates and adapt to different communication protocols, demonstrating flexibility and adaptability.
"With the rise of wireless networks and mobile communications, the role of telephone switches is changing. What will the future of communications look like?"
Terminology of telephone exchange
The terminology for telephone exchanges varies in different countries and regions. For example, "manual service" refers to telephone service that is answered by a human operator, while "dial-up service" is a method of completing calls by interpreting the number dialed by the operator. The "switch" in a telephone exchange is a device used to transfer calls, and the "concentrator" is a device used to concentrate traffic. The evolution of these terms demonstrates the adaptability of technology and language.
The future of automationToday, the automation technology of telephone exchanges continues to advance, from basic digital signals to today's multi-frequency signals. The advancement of switching technology has made communications faster and more convenient, greatly improving the user experience. The future of the telecommunications industry will depend on technological innovation and transformation of business models. How will all this affect our daily lives?
