It all begins with Plain Ordinary Telephone Service and the Public Switched Telephone Network. 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.

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.
