  • Gateways

  • Particularly if you are new to the telecommunications industry, this may seem like a daunting list, but this course is just the introduction to these topics. The following courses go into more depth in each area including VoIP, PSTN, Wireless, Ethernet, IP and MPLS.

    Through 20 plus years of instructor-led training, we have refined and fine tuned this material based on Course 101. We explain, in plain English, all the buzzwords and jargon demystifying IP telecommunications by explaining the key ideas and how they work together.

    This exhaustive course on wireless covers basics of radio, mobile and cell telecom, Wi-Fi and much more. Substantially augmented for our current decade with Wi-Fi 6 (802.11ax), 5G and Starlink.

    We start with the main ideas and terms associated with mobile networks which include transceivers, base stations, handoffs, backhaul and various concepts around cellular radio as well as digital radio.

    You will be able to see how a telephone connections works from a cellular device to a landline, and various strategies that allow other personal communication equipment to connect to the Internet through the mobile connection of a smart phone.

    Without getting lost though a maze of details, we will address these important technologies of spectrum-sharing. We will start with the first generation FDMA, then review GSM/TDMA (2G), then move on to 3G and CDMA, then carry on to 4G to finish at 5G and OFDM. We will take a more detailed look at how modems translate bits and bytes on subcarriers and also how OFDMA is handled in the 4G technologies as well as the 5G environment in order to dynamically link users and subcarriers.

    Next, we will cover WiFi, more specifically 802.11 wireless LANS. The components of these systems, the bitrates, frequency bands, the different versions for coverage up to WiFi 6. This last WiFi version is now using full-duplex with a number of concurrent devices through OFDMA as well as what can be called a theoretical 9.6 Gb/s. Additionally, we will dive into the security of WPA-2 and of WPA-3.

    We will conclude this course with an overview of various satellites in Geosynchronous and Low Earth Orbit (Starlink and Iridium Next).

    This is an introduction course to everything you wanted to know about Voice over IP. We cover the principles and fundamentals of a Voice over IP phone system, explaining VoIP, SIP and the other jargon, and how everything fits together.

    The course objective is to establish a solid, structured understanding of the technology and implementation required to communicate the thoughts in one person's brain to another person through a telephone conversation transmitted in IP packets.

    Going step by step we explain the related and supporting technologies including Ethernet MAC frames, codecs, and include video over IP.

    During the course of the lessons, we will cover:

  • VoIP Phones and Terminals
  • The flow through digitization, RTP, UDP, IP, MAC frames, and the physical medium
  • Softswitches, SIP Servers, Call Managers
  • Media Servers
  • Gateways
  • Connecting through LANs and WANs including Optical Ethernet
  • Key VoIP Standards
  • The Future: IP Dial Tone

  • This course is designed for anyone who wants to get up to speed on Voice over IP. The knowledge you gain about the components, operations, buzzwords and jargon will be career enhancing.

    It serves as an introduction to the topics explained in more detail in subsequent lessons.

    This is an essential course devoted to the PSTN (Public Switched Telephone Network) as well as POTS (the Plain Ordinary Telephone Service).

    An important building block for a good understanding of telecommunication is the operation and structure of the Public Switched Telephone Network, developed in the course of the last century and a half and still working all around the globe. This understanding will be essential for connecting the PSTN to, and continually supplanting the PSTN with IP telecom innovations.

    At the end of this course, you will have an excellent comprehension of the essentials of the phone system: client premise and Central Office, circuits and switches, remotes, trunks, loops, and how a call works from start to finish. We'll cover IXCs and LECs, analog and the voice band, sound, twisted pair, SS7 and DTMF.

    Built on our very popular Teracom's Course 101, improved and augmented in over two decades of seminars led by top instructors, we'll slice through technical terms to explain in plain English, the telephone system and telephony, clarifying the language and jargon, the fundamental principles, and how everything fits together.

    Richly illustrated with photographs of existing equipments inside a Central Office and in the external plant, this mixed media course is your first class ticket to understanding traditional telephony.

    With this course, you will build a frame of reference that will serve you for all the next courses. This reference model, called the OSI-7, will be broken down and divided in its constituent layers. We will describe and explain each function encapsulated within the layers.

    You will understand the purpose of layers and what they consist of. We will describe protocols using examples and a clear analogy to see how they get implemented within the layers and how these layers function together.

    At the end of this lesson you will have a good grasp of these concepts:

  • The protocols, their functions and standards.
  • What is an open system and its benefits
  • What a layer consist of
  • The description and function of the OSI Model
  • The 7 layers inside of the OSI Model
  • The name and purpose of each individual layer
  • How protocol stacks work, their definition and examples of protocols within individual layers
  • Introduction to standards organizations and some examples.

  • This course is about Ethernet: the essentials, hardware and usage including copper twisted pair, fiber and wireless, in-network core, in-building, PONs and MANs.

    We can conceive of Ethernet as a type of plumbing between devices. MPLS as well as IP are what moves inside the pipes. These are reviewed in our other lessons.

    MAC frames used in Ethernet have been a telecom success by allowing everything to be packaged identically regardless of the links: fiber, copper wire as well as wireless in all locations: network core, access network and also at the customer’s premise. Internetworking became simpler with the MAC frames standardizations. It also became more dependable and less expensive to implement.

    To get started, we will look at the essential concept of a broadcast domain for which a bus cable was the initial implementation.

    We will examine LAN interfaces to see how every interface is given a hard coded MAC address. In the MAC frame, the address shows the destinator because every broadcast domain receives that frame.

    We will look at an Ethernet switch (also referred to as Layer 2 switch or LAN switch) and the bus that is enclosed inside. We will examine how MAC addresses are learned by the switch and how the MAC frames can be passed to a single or multiple stations by the LAN switch.

    Next, we will cover VLANS which are software defined broadcast domains and how they are utilized to isolate traffic by enterprise level, work area or by device type or, at the carriel lever, by isolating traffic by customer.

    We will also cover how Ethernet 802.3 is implemented in its many standards starting from the 10BASE-5 all the way to 1000BASE-T. We will see Wi-Fi certification, twisted-pair wires and also wireless LANs (802.11).

    We will not forget Optical Ethernet with a detailed look at what constitutes the backbone of our telecom network, Ethernet on fiber.

    We will show you the underground installation of fiber cables and how bulk fibers are connected to equipment with the use of fiber splicing.

    Finally, you will learn the standards for Optical Ethernet ranging from 1 Gb/s all the way to 100 Gb/s.

    At the end of this lesson, you will have an understanding of:

  • Broadcast domains
  • MAC Addresses and how it identifies a LAN interface in a broadcast domain
  • The purpose of MAC frames
  • LAN switches and how how they work
  • VLANs and how they segregate devices in multiple broadcast domains
  • The series of standards known as the IEEE 802
  • The definition of code 1000BASE-T
  • Wi-Fi 2.4 GHz and 5GHz (MAC frames over Ether) and MAC frames bits get transmitted on radio frequencies
  • How Ethernet is wired in a workplace with twisted-pair (Cat 4, 5e and 6) on copper
  • The backbone of our telecom network: Optical Ethernet, what it is and examples such as MPLS networks, PONs (Passive Optical Networks) used in fiber to home, MANs (Metropolitan Area Networks)
  • How light is used in glass to transport MAC frames bits
  • The equipment at the end of fiber cables and how the cables are laid and connected
  • Definition and meaning of 100GBASE-ER4

  • The third layer of the OSI model can be referred to as the network layer. This course is all about Layer 3 with an emphasis on IP packets networks.

    The two main ideas behind packet networks are packet switching and bandwidth on demand. We will start by doing a refresh on the limitations of channelized TMD followed by a dive into bandwidth on demand or statistical TDM.

    We will look at how packet switching is achieved in the network by routers. More specifically, how packets are relayed between circuits and how network security is controlled by routers. You will gain an understanding of a routing table, its content and basic structure and we will discuss "Customer Edge".

    We will go through all that is necessary in IP addressing to fulfill its role in packet switching: Network Address Translation, Dotted decimal notation, the classes of an IPv4 address, DHCP, private vs public addresses, dynamic vs static addresses and we will conclude with a look at IPv6 including address assignment and allocation.

    At the end of this course, you will have a good understanding of:

  • Packets
  • Routers
  • Bandwidth on demand and Overbooking
  • Implementation, how and why
  • Private networks and what a network is
  • How a network is implemented by connecting links
  • How packets are moved by routers between broadcast domains
  • Packet filtering, security and basic network design
  • Routing tables: contents and basic structure
  • The Customer Edge
  • Classes A, B and C of Ipv4 address blocks
  • What dotted-decimal notation is
  • Dynamic and static addresses
  • Why and how DHCP is used for:
  • Assigning private and public addresses
  • Where, how and why these addresses are used
  • Network Address Translation (NAT)
  • IPv6 and how their addresses are allocated to ISPs
  • Many billions of billion IPv6 addresses for each residence?

  • Carrier Networks and MPLS is an updated complete course on networks built and operated by companies such as AT&T. We will see how these networks are achieved, how their customers connect to them and their services.

    Everyone who needs an overview of MPLS and carrier networks will benefit from taking this course. It will also be a great help to those seeking a strong foundation for project building as well as those who need environment-specific knowledge.

    Previously, our model was a private network, this simple framework for point-to-point circuits helped us cover bandwidth on demand, packets, network addresses and routers.

    This course will use this same model and apply it at the level of a carrier network. Bandwidth on demand service will replace dedicated lines as the service between the carrier and the customers.

    Our focus will be virtual circuits, a robust traffic management tool, and how MPLS is used to implement them. We will also see how differentiated services can be provided by MPLS and how it can implement convergence and aggregate traffic.

    We will skip unnecessary details and explain buzzwords to help you demystify:

  • What a carrier packet is, its network and services
  • "PE" Provider Edge and "CE" Customer Edge
  • Virtual circuits
  • Service Level Agreements
  • Traffic profiles
  • Convergence, integration as well as aggregation
  • Differentiated Service, Class of Service and QoS
  • Virtual circuits
  • Network technologies, particularly MPLS
  • What that means for TCP/IP
  • MPLS and integrated access
  • MPLS and business customer VPNs
  • How a single circuit can carry all these services
  • MPLS services and the internet
  • How IP packets are managed by MPLS
