PSTN (Public Switched Telephone Network)

PSTN (Public Switched Telephone Network) -Definition

The public switched telephone network (PSTN) is the network of the global public circuit-switched telephone networks, in much the same way that the Internet is the network of the world's public IP-based packet-switched networks. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital and includes mobile as well as fixed telephones. It is sometimes referred to as the Plain Old Telephone System (POTS).
