One cornerstone of a full, rounded base of knowledge of telecommunications is the structure and operation of the Public Switched Telephone Network, built over the past 135 years, still in operation in every country on earth - knowledge necessary for connecting the PSTN to, and steadily replacing the PSTN with IP telecom technologies.
In this course, you’ll build a solid understanding of the fundamentals of the telephone system: customer premise and Central Office, loops, trunks, remotes, circuit switching and how a telephone call is connected end-to-end. We’ll cover LECs and IXCs, sound, analog and the voiceband, twisted pair, DTMF and SS7. Updated for the 2020s.

Based on Teracom’s famous Course 101, tuned and refined over the course of 20 years of instructor-led training, we’ll cut through the jargon to demystify telephony and the telephone system, explaining the jargon and buzzwords, the underlying ideas, and how it all works together… in plain English.
Featuring many photos of actual equipment both inside a Central Office and in the outside plant, this multimedia course is an excellent way to get up to speed on traditional telephony.
