It all starts with the PSTN and POTS. We’ll begin with the basics of telephony: loops, trunks, circuits, analog, the voiceband… fundamentals that are key to understanding newer technologies and services. Then, we'll review switches, PBXs, Centrex and ancillary equipment like ACDs and IVRs. With this framework in place, we'll explore the telecommunications industry, understanding the main players and competitors, how LECs connect to IXCs, the switching hierarchy and how CLECs fit into the picture.
The topics in this course - how the telephone system and industry work, provide the essential foundation on which everything else, including digital communications, data circuits and networking are built. Whole series available on Devilwolfs
