Understanding the structure and operations of the PSTN, the Public Switched Telephone Network, is one cornerstone of a well-rounded knowledge of telecommunications. The Public Switched Telephone Network was built over the past 135 years and is still operating in every country around the world. This knowledge is necessary to understand how to connect the PSTN to IP telecom technologies, which are steadily replacing the PSTN.

In this course, you’ll gain a solid understanding of telephone system fundamentals: Central Office, customer premise, trunks, loops, remotes, circuit switching, and connecting a telephone call end-to-end.  We cover LECs, CLECs and IXCs, twisted pair, sound, analog and the voiceband, DTMF and SS7.
