Telefonikeskusjaam

Telefonikeskusjaam, often translated as telephone exchange or central office, is a facility that serves as a hub for telephone communications within a specific geographic area. Its primary function is to connect telephone lines of subscribers to each other and to the wider public switched telephone network (PSTN). Historically, these were manual operations where operators physically connected calls using switchboards. However, modern telefonikeskusjaamat employ automatic electromechanical or electronic switching systems to route calls efficiently.

The core components of a telefonikeskusjaam include switching equipment, which manages the connections, and transmission equipment, which handles the signals traveling to and from subscribers and other exchanges. It also houses power supply systems to ensure continuous operation. The capacity of a telefonikeskusjaam determines the number of telephone lines it can serve and the volume of calls it can handle. As technology has advanced, telefonikeskusjaamat have evolved to support a range of services beyond basic voice calls, including broadband internet access and digital communication technologies. In essence, the telefonikeskusjaam remains a critical infrastructure element for telecommunication networks.
