Answer Details
The transmission of telephone services from one country to another is facilitated by communication satellites.
Communication satellites are artificial satellites that orbit the Earth and are used to relay various types of telecommunications signals, including telephone calls, television broadcasts, and internet data. They are equipped with transponders, which receive signals from the ground and retransmit them to other locations around the world.
When a telephone call is made from one country to another, the signal is transmitted from the caller's telephone to a local exchange. From there, it may be transmitted to a long-distance carrier, which routes the call to a gateway that connects to the communication satellite. The satellite then relays the signal to another gateway located in the destination country, which connects to a local exchange that routes the call to the intended recipient.
Communication satellites have revolutionized international telecommunications by providing a reliable, cost-effective means of transmitting signals over long distances. They have greatly expanded global connectivity and facilitated the growth of industries such as international trade, tourism, and finance.
Overall, communication satellites play a critical role in the transmission of telephone services from one country to another, and they are an essential component of modern international telecommunications infrastructure.
