Public Switched Telephone Network | PSTN
The Public Switched Telephone Network (PSTN) refers to what we have historically known as the telephone network–that is, a circuit-switched network with physical connections (copper lines) connecting the two ends of a call. Before the use of the internet and Voice over Internet Protocols (VoIP), a PTSN (originally AT&T, which owned Bell Telephone) handled all of the calls.
