Fundamentals of Telecommunications is the first module of Teracom's acclaimed telecom training Course 101
Telecom, Datacom and Networking for Non-Engineers
, covering on Day 1 the Public Switched Telephone Network (PSTN) and Plain Ordinary Telephone Service (POTS), the voiceband, PBX, Centrex, ACDs, IVRs and call centers; LECs, LATAs, CLECs, IXCs and POPs; analog-digital conversion, DS0s, DS1s and DS3s; T1, T3, ISDN BRI and PRI, SONET and DWDM; multiplexing, channels and TDM, and finishing with an overview of wireless: cellular and mobility; AMPS, TDMA, GSM and CDMA, 3G and wireless LANs.
The content, its order, our analogies and explanations have been refined over the course of eleven years.
We start at the beginning of the story, progress through it in a logical order, and finish at the end.
We bust the buzzwords, explain the jargon, and the ideas and concepts behind the jargon.
Covering the topics in a systematic way, we build structured knowledge that lasts a lifetime.
You'll gain key concept-level knowledge that you can't get on the job, from magazines or vendors.
Many attendees tell us that this is training they wish they'd had years ago!
Following is the outline for Module 1, Fundamentals of Telecommunications, presented on Day 1 of Course 101, Telecom, Datacom and Networking for Non-Engineers. Click the links above for full information on this telecom training seminar.

1-1. Fundamentals of Telephony
Whether you're interested in telecom, datacom, wireless or Wide Area Networking, everything begins with the Public Switched Telephone Network and Plain Ordinary Telephone Service. We'll begin with a model for the PSTN, explaining analog circuits and circuit switching, as well as common telephony buzzwords and jargon, and an overview of SS7.
A. History of Telecommunications
B. The Public Switched Telephone Network (PSTN)
C. Analog Circuits
D. The Voiceband
E. Plain Ordinary Telephone Service (POTS)
F. Signaling System 7 (SS7)
1-2. Telecom Equipment
We'll round out our discussion of telephony with a practical overview of different types of equipment that can be connected to the telephone network. Without bogging down on details, we'll sort out switches, PBXs, ACDs, IVRs, Call Centers and modems, including a discussion of DSL and how it is provided.
A. Telephone Switches
B. PBXs vs. Centrex
C. Voice VPNs
D. IVRs, ACDs and Call Centers
E. Modems: Representing Data on Analog Circuits
F. DSL: Beyond the Voiceband
1-3. The Telecommunications Industry
With a basic framework in place, we'll review the telecommunications business, including companies, alliances, services and competition, and understand how each organization fits into the picture.
A. US Domestic Telcos / Local Exchange Carriers (LECs)
B. PSTN Switching Centers Before Competition
C. Accessing the Interexchange Carriers (IXCs)
D. Competitive Local Exchange Carriers (CLECs)
1-4. Digital Communications Concepts
We'll discuss what is really meant by "digital" and explain fundamentals like DS0 channels, the 64 kb/s rate and the digital hierarchy. We'll provide a practical overview of digital circuits, including T1, T3, SONET and ISDN. At a high level, we'll explore the different types of traffic that can be carried over these circuits, and how voice, data and video can be integrated.
A. Why Digital?
B. Analog and Digital: What Do We Really Mean?
C. Voice Digitization (Analog-Digital Conversion)
D. The Digital Hierarchy: DS0-DS3
E. Carrier Systems Overview: T1, T3, SONET, ISDN
F. Digital Circuit Applications
  G. Integration: Voice, Video, Data
1-5. Transmission Systems
Time Division Multiplexing (TDM) and digital carrier systems 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 what a multiplexer does and how these transmission systems work over copper wires and fiber, and carriers' "backbones" constructed of SONET rings on Dense Wave-Division Multiplexed fiber.
A. Establishing the Hierarchy: Time Division Multiplexing
B. The T1 Carrier System
C. How T1 Circuits Are Actually Provided
D. Fiber Optics
E. SONET, DWDM and Optical Networking: "Backbone" Transmission Networks
F. International Digital Hierarchies
1-6. Wireless Communications
We'll round out your knowledge of telecom fundamentals with wireless. We'll sort out different cellular technologies, including analog, PCS and 3G, and the pros and cons of different approaches like CDMA, TDMA and GSM. We'll also cover 802.11 wireless LANs and review satellite communications.
A. Wireless and Mobile Networks
B. First Generation Cellular: AMPS
C. Second Generation: PCS
D. Digital Cellular: Voice Communications
E. Spectrum-Sharing Technologies: AMPS, TDMA, CDMA, OFDM
F. Third-Generation (3G) Cellular, 4G, UMTS, HSPA, LTE
  G. Wireless LANs: 802.11 standards and WiFi
  H. Satellite Communications
