Fundamentals of Telecommunications

Module 1 of our famous core telecommunications training. Starting with the big-picture view of today's telecom network: convergence, broadband, network core and edge, Ethernet, IP and MPLS, network access, telecommunication service implementation, carrier interconnect, services: residential, business and wholesale. Continuing with fundamentals, then Internet, ISPs, data centers and the Cloud, finishing with how voice, text, images, video and data are represented as 1s and 0s to be carried in IP packets over networks.

Fundamentals of Telecommunications is the first module of Teracom's acclaimed telecom training Course 101 - Broadband, Telecom, Datacom & Networking for Non-Engineering Professionals.
Day 1 covers:

The content and its order were totally updated for the 2020s, yet, the explanations and analogies have been fine tuned over more than 20 years.

The key concept-level knowledge which you gain through this module, you cannot get from magazines, vendors or on the job.

Many attendees tell us they wish they'd had this training years ago!

Following is the outline for Module 1, Fundamentals of Telecommunications, presented on Day 1 of Course 101 - Broadband, Telecom, Datacom & Networking for Non-Engineering Professionals. Click the links above for full information on this telecom training seminar.

Module 1  Fundamentals of Telecommunications

We begin Course 101 with six chapters covering the fundamentals of telecom, explaining concepts, filling gaps and creating a solid knowledge base. First is a big-picture view and high-level pass of all the course topics. Then we progress logically: telecom fundamentals and provisioning of telecom circuits by carriers, followed by network fundamentals and IP packet networks. Next you learn about the business side of the Internet: Internet Service Providers, cloud computing, web services like AWS, and data centers. Then we review the services available today by category: residential, business and wholesale. Rounding out the fundamentals is digital media: voice digitization, digital text, digital images, digital video and digital quantities.

Module Objectives
  • Establish an up-to-date base in the fundamentals of telecom, datacom and networking.
  • Understand jargon and buzzwords. Fill in the gaps.
  • Understand the main technologies and solutions.
  • Establish a structure that project-specific knowledge can be added onto in the future.
  • Understand how everything fits together.
  • Obtain career-enhancing knowledge.
Module Content
  • Today's IP telecom network - converged, broadband.
  • Fundamentals of Telecom: pulses, modems, multiplexing, circuits.
  • Fundamentals of Networks: IP packets, MAC frames.
  • The Internet, ISPs, DNS and Net neutrality.
  • Data Centers, Web Services, and Cloud Computing.
  • Services: Wholesale, Business and Residential. SD-WAN and MPLS.
  • Digital Media: voice, text, images, video and data.

1. Introduction to Telecommunications

We begin with a high-level introduction to all aspects of broadband telecom. You learn about convergence and broadband concepts, today's telecom network, and the network components. We cover Ethernet, IP and MPLS and what each of these three key technologies does. Next, you learn how circuits are implemented end-to-end, and finally today’s standard services for residential, business and wholesale.

  1. Telecommunications History
  2. Convergence
  3. Broadband
  4. Today's IP Telecom Network
  5. The Network Core
  6. Ethernet, MPLS, IP
  7. Network Access
  8. Telecommunication Service Implementation
  9. Inside the Network Cloud
  10. Equipment for the Network Edge
  11. Interconnecting to Other Carriers
  12. Services: Residential, Business and Wholesale

2. Telecom Fundamentals

In Telecom Fundamentals, you develop a solid foundation in the ideas: the circuit elements; servers, clients, terminals and peers; representing bits on fiber with pulses; and representing bits on cable TV, DSL and wireless with modems. Next you learn how many users' traffic is carried on common facilities by overbooking and sharing capacity: Time Division Multiplexing, Frequency Division Multiplexing and Bandwidth on Demand.

  1. Circuits
  2. Servers, Clients, Terminals and Peers
  3. Pulses: Bits on Digital Circuits
  4. Modems: Bits in Frequency Channels
  5. Serial and Parallel
  6. Sharing: CATV, FDM on Radio and Fiber
  7. Sharing: Channelized TDM
  8. Efficient Sharing: Bandwidth on Demand and Statistical TDM

3. Network Fundamentals

Next, we ensure you develop a solid foundation in network fundamentals and the jargon. Packets in frames, or what used to be called "data communications", is the basis for today's converged telecom network. From a conceptual level, we explain basic circuit configurations, how routers relay packets between circuits, and how packets are transmitted between devices in frames. You come up to speed on and understand how MAC frames, IP packets and MPLS labels work together.

  1. Unbalanced Configurations: WiFi, CATV, PON, CAN-BUS
  2. Balanced: LANs and Ethernet
  3. Frames and MAC Addresses
  4. Networks
  5. Routers, Packets and IP Addresses
  6. MAC Frames versus IP Packets
  7. IP Packets
  8. MPLS Labels

4. The Internet, Cloud Computing, Web Services and Data Centers

The Internet was started to send email messages containing text. It is now used for worldwide converged broadband communications. Here you learn what an Internet Service Provider (ISP) does to get packets delivered world-wide. We review web clients, web servers, browsers and apps, then understand the enormous business of cloud computing, web services and data centers.

  1. Was the Internet Designed to Survive Nuclear War?
  2. The Inter-Net Protocol
  3. Internet Service Providers
  4. Domain Name System

  7. Web Services
  8. AWS and Cloud Computing
  9. Data Centers
  10. The Net Neutrality Controversy

5. Telecom Services

Understanding where the real money is made, that is services with recurring billing, is important to any foundation in telecom. We review Residential, Business and Wholesale services, and identify the offerings and today's standard choices in each area. For residences, we cover Broadband Internet, Internet VoIP with a PSTN phone number, plus streaming video. In the business category, we review VPNs, Centrex, SIP trunking and PRI. Finally in wholesale services, we explain Carrier Ethernet, IP transit, wavelengths and dark fiber.

6. Digital Media: Voice, Text, Images, Video, Quantities

All media types are carried by the converged network: voice, text, images and video in packets. Digitizing the media, using 1s and 0s, is an essential first step for it to be carried in packets. We learn how voice is first digitized and then reconstructed, and the current G.711 64 kb/s standard. We see that the same principles apply to image formats like jpg and video formats like mp4. We explain binary and hexadecimal, and finally unicode for text and even emojis.

  1. What We Really Mean by Analog and Digital
  2. Continuous and Discrete Signals
  3. Voice Digitization using Analog to Digital Conversion
  4. Voice Reconstruction using Digital to Analog Conversion
  5. Digital Voice: G.711 64kb/s Standard
  6. Digital Video: MP4 / H.264, 4K, HD
  7. Digital Images: JPG, PNG, GIF
  8. Digital Emails Images: MIME
  9. Digital Quantity Formats: Binary, Hex
  10. Digital Text Formats: ASCII, Unicode
