V1 Fundamentals of Telecom 1

The PSTN • Telephony • Telecom Equipment • The Telecom Industry

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.

2 hours 22 minutes of career- and productivity-enhancing training!

Many people tell us this is training they wish they'd had years ago.

V2 Fundamentals of Telecom 2

Voice Digitization • DS0-DS3 • Digital Transmission and TDM • T1 • T3 • ISDN • SONET • Fiber • DWDM

In this 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 and G.711 is, and take a practical tour of digital circuits, including T1, T3, SONET and ISDN.

At a high level, we'll see how voice and data is integrated in channelized systems, including the still widely-deployed ISDN PRI PBX trunk carriers.  Then, we'll take a closer look at how this is actually done, with Time Division Multiplexing (TDM) to implement the idea of channels. Without getting bogged down on technical details, we'll provide you with a basic understanding of how these kind of transmission systems work, including T1, PRI and SONET.  

You will learn the essentials of fiber, fiber optics and fiber cables, how 1s and 0s are communicated over fiber... and how bitrates of 100 Gb/s and more are achieved using Dense Wave Division Multiplexing (DWDM).

TDM transmission systems were designed for digital voice communications, and are used for data and Internet infrastructure in non-channelized mode. This video course provides you with the concrete knowledge of channelized telecommunication circuits necessary to a full understanding of data circuits and network services.

New builds are packet-switched bandwidth-on-demand systems, networks built of Layer 2 Ethernet LAN switches exchanging MAC frames over point-to-point fiber circuits, with routers and IP addresses to direct the traffic from one circuit to another.  That is covered in V3, V4 and V5.

V3 Fundamentals of Datacom and Networking

WANs and LANs • Frames and Packets • Equipment, Services and The Network "Cloud"

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 chapter, 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 that there are 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.

V4 Understanding Networking 1

OSI Layers • Protocol Stacks • The FedEx Analogy IP Addressing, DHCP, NAT • Bandwidth on Demand Services • Frame Relay • ATM • MPLS

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.

Our training has been taught to wide acclaim across North America since 1992 and is designed for the non-engineering professional needing an overview and update, and for those new to the business needing to get up to speed quickly on telecommunications, data communications, IP, MPLS, wireless, networking, Voice over IP (VoIP) phone systems, SIP and security.

Our emphasis is conveying the key concept-level knowledge in plain English - which you can't get reading trade magazines or talking to vendors. We put in place a solid, valuable and long-lasting understanding. It is our goal to bust the buzzwords, demystify the jargon, and cut through the double-talk to present a clear, cohesive picture.

Teracom's proven instructor-led training courses are top-notch, top-quality and right up to date with the topics and knowledge you need.  These courses have been developed and refined over twenty years of providing this training for organizations including AT&T, Verizon, Bell Canada, Intel, Microsoft, Cisco, Qualcomm, the CIA, NSA, IRS, FAA, US Army, Navy, Marines and Air Force and hundreds of others.

Teracom's instructors are professionals with both deep and broad experience working in the business, plus the ability to convey knowledge in a way that you understand, while keeping your attention and having some fun along the way.
