Public Switched Telephone Network (PSTN) is the global collection of public circuit-switched telephone networks originally designed to support circuit-switched voice communication. The PSTN provides the traditional Plain Old Telephone Service (POTS) to networks in nations across the world, essentially connecting any two phones in the world together. Originally a series of fixed-line analogue systems, PSTN is now almost solely digital in its structure.
