DVD Video Course V1 - Fundamentals of Telecom 1: The PSTN . Telephony . Telecom Equipment . The Telecom Industry - preview
Fundamentals of Telecom 1
The PSTN • Telephony • The Telecom Industry
Telecom Equipment
Length 142 minutes. 55-page student manual.   detailed course outline   brochure  
ISBN 1-894887-26-3
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.
"Loops" is a free sample, from Lesson 1.03 of this DVD.

T1 • T3 • ISDN • SONET • Fiber and DWDM
Length 124 minutes. 63-page student manual.   detailed course outline   brochure  
ISBN 1-894887-29-8
In this course, we understand the concepts, standards and technologies for transmitting voice calls using traditional techniques. We'll give you a real understanding of what "digital" actually means and how it is implemented. You'll understand DS0 and the digital hierarchy 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 via TDM and channelization. Then we'll take a closer look at how this is actually done, with multiplexers, pulses and repeaters, copper, fiber optics, fiber rings and WDM.
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 course provides you with the concrete knowledge of the infrastructure necessary to a full understanding of circuits and services.
"Voice Digitization" is a free sample, Lesson 1.09 of this DVD.

The Network "Cloud"
Length 106 minutes. 65-page student manual.   detailed course outline   brochure  
ISBN 1-894887-32-8

In this course, we'll begin by establishing a model for a data communications circuit, then provide examples and context for each of the components of the model, and review different circuit configurations including LANs and WANs.

In the second part, we'll look at how data is formatted for transmission, beginning with the older concepts of "synchronous" and "asynchronous", then cover the newer ideas of frames and packets, how frames and packets are related, and the addresses on frames and packets, and the structure of IPv4 packets.
We'll complete this course with an understanding of the "Network Cloud", why people use clouds to draw networks, and what is really going on inside that cloud.
This set of topics, particularly the understanding of packets and frames, the addresses on each, and how they are related; and the idea of three kinds of network services - and three kinds of edge equipment - is the foundation for all further study of LANs, WANs, IP and just about any other kind of communications, including Voice over IP.
"Packets, Frames, Addresses, Routing" is a free sample from this DVD.

Understanding Networking 1
OSI Layers • Protocol Stacks • The FedEx Analogy
IP Addressing, DHCP, NAT • Bandwidth on Demand Services
Frame Relay • ATM • MPLS
Length 127 minutes. 58-page student manual.   detailed course outline   brochure  
ISBN 1-894887-35-2

This course builds on the basic packet, frame and IP networking concepts of Course V3, Fundamentals of Datacom and Networking, to put in place a solid understanding of protocol stacks, the OSI model and layers and IP addressing including address classes, static vs. dynamic public vs. private and network address translation.

In Part 3, we move to the next higher level of knowledge, understanding packet networks and bandwidth on demand services from telecommunication service providers. After understanding the core concepts, including virtual circuits, we use the grand-daddy of packet services, X.25 to explain jargon: connection-oriented vs. connectionless and reliable vs. unreliable packet networks. Then we progress through technologies: Frame Relay, ATM and finish with MPLS. We'll trace the flow of TCP and IP packets from server to client across Frame Relay, then see how the same TCP/IP works over MPLS.
IP over MPLS will end up replacing all other services including ISDN, T1s, Frame Relay, native ATM. Understanding the OSI layers, how a protocol stack works and TCP/IP over MPLS is career-enhancing knowledge.
"The FedEx Analogy" explains how the OSI Layers and protocol stacks work.
It is a free sample taken from this DVD.

"I highly recommend the DVD series"
Excellent training series: The instructor intermixes a concise, easy to understand, unique presentation style with a twist of humor to keep it interesting. Eric uses easy to understand analogies to relate high-tech ideas in a way everyone can understand. This is an excellent, one stop, de-facto resource not only for training but also for the reference library.

"This type of quality builds my faith in humanity"
Worth every nanocent. I have watched seven DVDs since I got them three days ago (bought 9)—which basically means that I am doing nothing else. Very impressed with the clarity and structure of the material. I will never take another class where the moron in the front holds everyone back. So, make more videos.
Would you recommend that other people buy these courses? Would you buy them again?
Were the courses useful?

Very useful refresher. Very impressed that they are up to date. This type of quality builds my faith in humanity.

Which did you get?

All of them.

Was the content what you needed?

Everything that I wasn't sure about is clear now—about VOIP and telecom. As a LAN guy, I used to be real quiet during telecom discussions. Now I can contribute with confidence.

How was the production quality?

Excellent. No unnecessary bells and whistles to distract us.

Did you like the multimedia experience, with the instructor, graphics and bullets layered together?


How did you watch them? On a PC? On a television? In a group?

I watched them with my dogs on my PC, and on my 57 inch when I needed to relax.

Well done!! I would love to shake Eric’s hand.

"Got the job!"
I just wanted to say thanks for your VoIP DVD video course set. After taking your course,
I had my interview.
At the interview, I was actually able to dazzle the CEO of this company my SIP/VoIP knowledge!
I got the job and have been doing rather well.
My family appreciates the better opportunity I was able to attain because of your training.
