telephone exchange

A telephone exchange is a system that connects calls between different phones. When you dial a number, your phone sends signals to the exchange, which identifies the recipient's number and finds the best route to connect the call. It uses a variety of switching equipment to establish, maintain, and terminate connections efficiently. Think of it as a central hub that manages all the communication links, ensuring your voice data reaches the right person quickly and reliably. Modern exchanges are mostly electronic, automating these processes for faster and more reliable telephone communication.
