Course V1: Fundamentals of Telecommunications
The PSTN • Telephony • Telecom Equipment • The Telecom Industry
Produced 2006. Length 142 minutes. DVD-R NTSC format. 55-page 8.5" x 11" softcover bound workbook.

It all starts with the Public Switched Telephone Network (PSTN) and Plain Ordinary Telephone Service (POTS).
We’ll begin with the basics of telephony: loops, trunks, circuits, analog, the voiceband… fundamentals that are key
to understanding of newer technologies and services.
To complete the picture, we take a practical journey through different types of equipment. We'll review switches,
PBXs, Centrex, multiplexers and routers, as well as ancillary equipment like ACDs, voice mail and interactive voice
response (IVR) systems.
With this framework in place, we'll review the telecommunications industry and understand the main players and
competitors, how Local Exchange Carriers connect to Inter-Exchange Carriers and how CLECs fit into the picture.
The topics in this video 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.

Course V2: Fundamentals of Telecommunications 2
Voice Digitization • DS0-DS3 • Transmission • TDM • T1 • T3 • ISDN • SONET • Fiber • DWDM
Produced 2006. Length 124 minutes. DVD-R NTSC format. 63-page 8.5" x 11" softcover bound workbook.


In this video course, we drill into the technology a bit, to understand the concepts, standards and technologies for
actually transmitting voice calls from one place to another. We'll give you a real understanding of what "digital"
actually means, and how it is implemented. We’ll explain what a "DS0" is, and take a practical tour of digital
circuits, including T1, T3, SONET and ISDN. At a high level, we'll see how voice, data and video can be
integrated. Then, we'll take a closer look at how this is all actually done, with Time Division Multiplexing (TDM)
and digital carrier systems that are the technologies at the heart of telecommunications networks. Without getting
bogged down on technical details, we'll provide you with a basic understanding of how transmission systems work,
including T1 over copper wires and SONET over fiber.
Most of the transmission systems we have in place were designed for digital voice communications using these
techniques... but they are also used for data and networking. This video course provides you with the concrete
knowledge of the telecommunication circuits necessary to a full understanding of data circuits and network
services.
