Course 101 Part 1: The Fundamentals

The first part is six chapters covering the fundamentals of telecom, explaining concepts, filling gaps and establishing a solid base of knowledge. First is a big picture view with a high-level pass introducing all the course topics. We then progress logically: how carriers provision telecom circuits, telecom fundamentals, and IP packet network fundamentals. Then we explain the Internet as a business: web services like AWS, ISPs, cloud computing and data centers. We review the services available today by category - residential, business and wholesale. The fundamentals are rounded out with digital media concepts: how voice is digitized, digital images, digital video, digital quantities and digital text.

Content Part 1: Fundamentals of Telecommunications

	Broadband converged IP telecom network
	Telecom fundamentals: pulses, multiplexing, modems
	Network fundamentals: MAC frames and IP packets
	ISPs, The Internet and Net neutrality
	Cloud Computing, Web Services, Data Centers
	Residential, Business and Wholesale Services
	Digital Media: digital voice, images, video, data, text

Course Descriptions

1. Introduction to Telecommunications
We begin with a big-picture, comprehensive introduction to broadband telecom: the ideas of broadband and convergence, today's telecom network, the various parts of the network, and three key technologies: IP, Ethernet and MPLS, explaining what they are and what they do. We cover end-to-end how a circuit is implemented, and identify typical residential, business and wholesale services.

2. Telecom Fundamentals
You'll receive a firm foundation in the fundamental concepts of telecom: elements of a circuit; clients, servers, peers and terminals; how pulses are used to represented bits on fiber; and how modems are used to represented them in wireless, cable TV and DSL. Next you'll learn how shared capacity is used to carry traffic from many users on common facilities through Frequency Division Multiplexing (FDM), Time Division Multiplexing (TDM), overbooking and Bandwidth on Demand.

3. Network Fundamentals
Next, you'll receive a firm foundation in network fundamentals and jargon. Today's converged telecom network developed from what we use to call "data communications", that is packets in frames. Staying out of the details, we cover basic circuit configurations, learn how routers relay packets between circuits, and how packets are transmitted between devices in frames. We fill gaps and bring you up to speed on MAC frames, IP packets and MPLS labels, including the purpose of each and how they work together.

4. The Internet, Cloud Computing and Data Centers
The Internet began in order to send text email messages and is now converged broadband communications worldwide. Here, we explain what exactly an Internet Service Provider (ISP) does, and how they can get packets delivered worldwide. We review browsers and apps, web clients and web servers, and then explain the huge business of cloud computing, web services and data centers.

5. Telecom Services
A complete foundation in telecom must include understanding where the money is, which is in services with recurring billing. We organize services into the categories of Residential, Business and Wholesale, and identify the current choices and offerings in each category. We include Broadband Internet, Internet VoIP with a PSTN phone number, and video streaming for residences; in the business category VPNs, PRI, Centrex, and SIP trunking; and wholesale services wavelengths, dark fiber, Carrier Ethernet and IP transit.

6. Digital Media: Voice, Video, Images, Quantities, Text
The converged network carries all types of media: voice, text, video, and images in packets. Digitizing the media is the essential first step, which means representing media using 1s and 0s, so it can be carried in packets. You'll learn how voice is digitized and then reconstructed applying the G.711 64 kb/s standard. You'll see that the same principles are applied to images in formats like jpg, and to mp4 videos. We review binary and hexadecimal, and then finish with unicode for emojis and text.

Course 101 Part 2: Telecom Technologies

In the part two of the course, we focus on the three main technologies used to transmit information from one location to another which we group into wireless, fiber and copper. You'll learn about mobile network components and operations, the wireless spectrum, 4G LTE, 5G, Wi-Fi, fixed wireless broadband home internet and satellites. We cover optical basics, networks configured with point-to-point fibers using Optical Ethernet, fiber to the premise, in the core and metro, and wave-division multiplexing. We round out the discussion with copper-wire technologies: POTS and DSL on twisted pair, T1, Hybrid Fiber-Coax cable TV systems and the categories of LAN cables.

Content Part 2: Telecom Technologies

	Wireless: Cellular, Mobile Internet, 4G, 5G
	3.5 GHz Broadband Home Internet, Wi-Fi, Satellite

Course Descriptions

7. Wireless
In this segment, we focus on wireless transmission. We identify basic principles of operation and the components of a mobile network. We explain the requirements for mobility, coverage and capacity, and the reason cellular radio systems are used. You’ll understand how mobile to land-line (PSTN) phone calls are connected, and about roaming, mobile Internet and virtual operators. We cover mobile 4G LTE and 5G, plus fixed wireless broadband home internet. You'll learn about WiFi and the 802.11ax standard, and finally satellite communications.

8. Fiber Optics
The network core is created by connecting routers to other routers point-to-point with fiber. Telephone companies used to run copper wires to access every home in a suburb. They are now investing to run fiber to access every home. In this segment, you'll learn the basics of fiber, wavelengths, WDM and the makeup of fiber cables. You'll learn how Optical Ethernet implements the fiber connections, plus how Optical Ethernet is used in fiber to the premise via PONs (Passive Optical Networks) in the core and in metro areas.

9. Copper
The physical access circuit in suburbs and cities, before wireless and fiber, was two copper wires for telephone and cable TV service. These wires are used today to deliver broadband. In this segment, you'll learn how the twisted pairs, put in place originally for analog POTS telephone service, are used to deliver DSL broadband service; how broadband on coaxial cable is moved by cable modems; and how both are delivered to the neighborhood on fiber then on copper to the premise. To finish, we explain digital on copper wires: T1s and LAN cables.

Course 101 Part 3: Equipment, Carriers and Interconnect

In the third part, we cover the equipment, connected by the wireless, fiber and copper explained in Part 2, to form networks, and the purpose and place of each. You'll learn where and how physical connections are made for PSTN phone calls, CLEC services and for Internet traffic.

Content Part 3: Equipment, Carriers and Interconnect

	Layer 2 Switches and Core Routers
	PBXs and CO Switches vs. Softswitches, Gateways
	Switched Access, Internet Exchanges, POPs, CLECs

Course Descriptions

10. Telecom Equipment
In this segment, we review the various types of telecom equipment, starting with the essentials for the broadband telecom network: IP/MPLS routers and Ethernet switches, comparing costs and capabilities. Next, we review the various types of broadband customer premise equipment. To explain call managers, soft switches and SIP servers, we compare them with legacy PBXs and CO switches to see the fundamental differences. We finish with gateways and how gateways convert packets to channels.

11. Carriers and Interconnect
For customers of different carriers to commmunicate, the carriers' networks must be physically connected. In this segment, we explain how the Internet is implemented, with transit agreements and peering at Internet Exchange buildings. We also explain about POPs in toll centers: where and how local exchange service providers: mobile providers, ILECs and CATV, connect together and connect to other carriers to enable phone calls using a PSTN phone number; and how calls are set up using SS7. We end by explaining where a CLEC fits in the story by collocating equipment in wire centers.

Course 101 Part 4: Networking

The final part of the course is focused on IP networking and MPLS. We start with the OSI Reference Model explaining its layers and providing a structure for discussion: what the layers are, what a layer is, the functions of each layer, and the standard protocols for each layer. Then we discuss Layer 2: broadcast domains, Ethernet, 802 standards and VLANs. Next, Layer 3: IP addresses, IP routers, DHCP, Network Address Translation, public and private addresses and IPv6. We cover MPLS, the core traffic management system, and how it is used to implement VPNs, service integration, classes of service and traffic aggregation. We conclude with a roundup of technologies, a top-down review and peek into the future of telecommunications.

Content Part 4: Networking

	OSI Layers and Protocol Stacks
	LAN switches, Ethernet LAN and VLANs
	IP addresses, Routers, DHCP, public-private addresses, NAT
	IPv6 address types and allocation
	Carrier networks, Class of Service, SLAs
	MPLS for CoS, VPNs, aggregation and integration
	Practical solutions and project methodology

Course Descriptions

12. The OSI Layers and Protocol Stacks
To interoperate systems, so many functions must be performed that a structure is needed to organize the functions in order to treat separate issues separately. We begin part four with the ISO 7-Layer Open Systems Interconnection Reference Model, the most commonly-used structure. We explain what a layer is, each layer's purpose, give examples of protocols used to implement layers like TCP and IP, and provide a practical view of how protocol stacks work for applications like VoIP and web surfing.

13. Ethernet, LANs and VLANs
Ethernet is used for linking devices point-to-point in all network parts, thus implementing OSI model Layers 1 and 2 together. In this segment, we review the basic principles of LANs and Ethernet formalized by stardards in the 802 series, plus the concepts of broadcast domains, MAC addresses and MAC frames. You'll learn how Layer 2 switches, also called LAN switches, connect devices, and use VLANs to separate devices for basic network security.

14. IP Networks, Routers and Addresses
This segment is focused on IP which is used to implement Layer 3. We start with IP addressing: address classes, DHCP, subnets, static and dynamic addresses, private and public addresses and Network Address Translation. We use a simple IP network to show how routers relay packets from link to link to implement the network, and also serve as a point of control denying communications based on port number and/or IP address. We finish this segment with IPv6 addressing.

15. MPLS and Carrier Networks
In the future everything, including television and phone calls, will be carried in IP packets. However, IP in itself does not provide any way to manage or prioritize traffic to guarantee picture quality or call quality. MPLS is used in a carrier's network core to implement those functions. In this segment, we cover the basics of carrier networks and the need for Service Level Agreements. You’ll gain practical knowledge on how MPLS works and how carriers use it to implement different Classes of Service, VPNs, traffic aggregation and service integration.

16. Wrapping Up Course 101
The final segment brings together all of the concepts with a top-down review. You’ll gain valuable insights into telecom methodology and project management. We review broadband, telecom, datacom and networking services, technologies and solutions. We conclude by peeking at the future of telecommunications, when the Internet and telephone network become the same thing.

Course 130 Part 1: Voice over IP and SIP

The first six segments of this course are focused on Voice over IP and SIP. We bring you up to speed on VoIP, what SIP is, how it works, SIP Trunking, all the buzzwords, jargon and concepts, and VoIP system pros and cons: Call Manager / Softswitch vs. Hosted PBX vs. Cloud Service vs. IP Centrex.

Content Part 1: Voice over IP and SIP

	The operation and components of VoIP phone systems
	Internet VoIP telephone service
	VoIP systems for Businesses: SIP servers, call managers, cloud services, hosted PBX, Centrex
	What SIP is and how SIP works
	Voice quality: packet loss, delay, jitter
	SIP Trunking and Carrier Connections

Course Descriptions

1. VoIP Components, Systems, Standards, Jargon and Buzzwords

We start with VoIP buzzwords and jargon, the basics of voice in IP packet communications, what the system components are, what each component does: soft switches, terminals, media servers and gateways, plus the main protocols and standards used in VoIP systems. We finish with "where this is all headed" and what will basic “telephone” service be in 20 years.

2. VoIP for Individuals
"Voice over IP" can be connected in many different ways. We start explaining VoIP phone calls by understanding how it all began: individuals phoning each other over the Internet. We demonstrate Internet VoIP telephone service with a Voice over IP phone call over the Internet to a Landline. We trace the voice packets from one end to the other through all of the circuits, devices and carriers involved, starting from a laptop through the Internet and then back to a cellphone from someone in the class.

3. VoIP Implementations for Businesses
We compare and contrast the different business choices for a VoIP phone system: replacing a PBX with a Softswitch / Call Manager; upgrading an existing PBX; implementing a Hosted PBX; Cloud-based services; using a Softswitch as a Service; and IP Centrex from a phone company. You’ll have the knowledge to differentiate with confidence between VoIP architectures and discuss the pros and cons of the options.

4. SIP and Call Flow in the IP World
SIP is the standard, open protocol for setting up VoIP telephone calls. The Session Initiation Protocol must be adhered to by all standards-based VoIP systems. It defines the messages and procedure used to set up a telephone call or other types of IP communication. We explain what SIP is and how it works and fits in with call managers and softswitches; demystify the jargon like proxy server; and trace the steps to establish an IP phone call one step at a time. In the end, you'll understand how telephone calls happen in VoIP phone systems – perhaps worth attending the course in of itself!

5. Voice Quality
Call quality is most important, particularly to the callers! In this segment, we explain what factors affect VoIP quality and how to correct any problems. You'll learn the factors that affect voice quality including codec, delay, jitter and lost packets, and how it is measured. We demystify how packets get “lost” or delayed, and you'll hear the resulting effects. We finish with a checklist of practical tips and recommendations to ensure success.

6. VoIP Carrier Services
We round out the VoIP part of the course with carrier connections. We begin with Class of Service performance guarantees in SLAs, Service Level Agreements, and end with selecting a VoIP carrier. We cover SIP trunking as a replacement for PBX trunks in business phone systems; how incumbent, cellular, cable and internet carriers connect for PSTN-VoIP phone calls; and connecting with Megaco and gateways.

The VoIP section finishes with a group exercise, fill-in-the-blank Final Exam, to identify all the pieces of information need to make a VoIP telephone call happen in each OSI Model layer. Don’t panic: the class divides into groups to do the open book exam together. This exercise is very useful to confirm the knowledge gained to this point in the BOOT CAMP week.

Course Descriptions

PART 1: THE BIG PICTURE
1. INTRODUCTION TO BROADBAND CONVERGED IP TELECOMMUNICATIONS
We begin with a comprehensive, big-picture introduction to today's telecom network covering the concepts of convergence and broadband, the different parts of the network, and the three key technologies (Ethernet, IP and MPLS): what they are, what they do. We cover service implementation end-to-end and today’s typical business, residential and wholesale services.

2. FUNDAMENTALS OF VOIP
Next we go into the fundamentals of VoIP: communicating voice in IP packets - the basics, demystifying the buzzwords and jargon, and explaining the VoIP telephone system components like soft switches and gateways in plain English, what each does, and the protocols like SIP.

3. NETWORK FUNDAMENTALS
In this module, we cover the essential technologies and concepts of IP networks. We review basic circuit configurations, and begin to explain how MAC frames are used to communicate IP packets, how routers are used to relay packets between circuits, and how MPLS implements traffic management. These topics are reviewed in detail on Day 2.

4. THE MANY DIFFERENT IMPLEMENTATIONS OF VOIP
“Voice over IP” can be implemented in many different ways. We review the various flavors of VoIP one by one, comparing and contrasting the implementations and architecture choices. We begin with Internet telephony, then we will discuss VoIP at the telephone company, connecting VoIP to older systems, and finally new services such as SIP Trunking. We will compare the pros and cons of choices for a VoIP system including buying it from the phone company; buying your own softswitch / call manager; renting a Hosted PBX; or cloud solutions. You will gain the required knowledge to differentiate VoIP architectures confidently and discuss the advantages and disadvantages of the options. We finish by discussing interesting uses for VoIP beyond phone calls.

Class Exercise: Tracing a VoIP Call from Internet to Cellphone End-to-End
We initiate a telephone call from a computer in the classroom, using a VoIP service via the Wi-Fi and the Internet, to a cellphone of someone in the classroom. We identify the path the voice packets travel end-to-end between the two sets of microphones and speakers from one device, circuit, and company to the other. This will solidify your understanding of VoIP phone calls, the telecom business and how it is all connected.

PART 2: VOIP AND SIP NUTS AND BOLTS

5. PACKETIZED VOICE AND SOUND QUALITY
In this module, we cover exactly what packetized voice is, how it is implemented, and the various standards used. You will learn about the factors which affect sound quality, and how packets get “lost” in a network. We listen to sound clips with impairments, and provide you a practical checklist of recommendations and tips for ensuring success.

Class Activity: Sound Clips with Impairments
Listening to the sound clips, you will hear the results of different levels of uncorrected packet loss, delay, and jitter, and understand how the sound quality of the reproduced speech is affected at the far end.

Bonus! A large PDF poster is included for all students explaining Voice over IP call quality metrics and thresholds.

6. SIP AND SOFTSWITCHES
SIP (Session Initiation Protocol) is the open, standard protocol used to set up Voice over IP phone calls. It must be implemented by all VoIP systems claiming to be “compatible” or “standards-based”. SIP prescribes the procedure and messages to set up phone calls - or any other kind of IP communication. In this module, we cover what exactly is entailed in setting up a VoIP phone call, what SIP is and how it works, the jargon like registration, proxy server, and location server, how SIP relates to softswitches and call managers, and the establishment of an IP telephone call step by step. By the end, you’ll understand how VoIP telephone calls are set up which may, in itself, be worth attending the course!

7. SIP TRUNKING AND CARRIER CONNECTIONS
We complete the VoIP part of the course with carrier connections, beginning with the Class of Service performance guarantees and ending with the transmission choices: MPLS VPN, SIP trunking and SD-WAN. We cover replacing PBX trunks with SIP trunking for business telephone systems; connecting using gateways and Megaco; and how internet, cellular, cable and incumbent carriers connect PSTN VoIP phone calls.

Case Study: Migrating A Five-State Organization to VoIP comparing SIP Trunking vs. SD-WAN
To solidify your understanding of VoIP telephone systems and carrier services, and perhaps even gain valuable insights into your own situation, we examine the PBX replacement strategy of a multi-state organization, and the question of implementing internal communications by SIP trunking, PBX trunks, or SD-WAN.

PART 3: THE IP NETWORK

8. THE OSI LAYERS AND PROTOCOL STACKS
The last day is focused on the modern broadband converged IP-based telecom network. We begin by organizing the discussion with the OSI 7-Layer Reference Model. We explain what a layer is, what the layers are, and provide examples of protocols such as TCP and IP and show how they interrelate in a protocol stack.

9. ETHERNET ON COPPER, FIBER AND WIRELESS
OSI model Layers 1 and 2 are implemented together using Ethernet throughout the network, for point-to-point links between devices. In this module, we review the basic principles of LANs and Ethernet, how Ethernet is formalized by the 802 series of standards, MAC addresses concepts, MAC frames and broadcast domains. You’ll learn how LAN switches / Layer 2 switches connect devices, and how, for basic network security functions, VLANs separate devices. The module finishes with Ethernet on fiber, which is called Optical Ethernet, and over radio, which is called Wi-Fi.

10. IP NETWORKS, ROUTERS AND ADDRESSES
This module focuses on IP and Layer 3. We start with IP addressing: IPv4 address classes, DHCP, subnets, static and dynamic addresses, private and public addresses and NAT. Using the simplest IP network, we explore how the network is implement by routers relaying packets from link to link. We show how routers also act as a control point to deny communications based on port number and/or IP address. We complete the module with IPv6 addressing.

Class Exercise: IP and MAC Addresses
Using the Windows interface, we determine the current IP and MAC Addresses of a computer in the classroom, and the public and private IP addresses for the Edge Router and NAT it is connected to. This will help you to visualize what IP addresses are, plus cover two of the questions for the Final Exam.

11. CARRIER NETWORKS AND MPLS VPNS vs SD-WAN
IP packets can carry anything, including phone calls or the Super Bowl. However, IP in itself does not provide any way to manage traffic or prioritize to guarantee the call quality or picture quality. At the core of a network, MPLS is used by the carrier to implement those functions. This module will complete your knowledge of the basics of carrier networks plus the important concept of Service Level Agreements. Then you’ll gain an understanding of how MPLS works practically and how carriers use it to implement MPLS VPNs, service integration, traffic aggregation and different Classes of Service; and then contrast it with a cheaper solution: Internet VPNs and SD-WAN.

Course Exam
The in-class Course Exam finishes the three days.
The good news: it is done in groups, open book. The exam can be optional.

It requires identifying the information needed at each layer for a VoIP phone call to take place, and the way that the phones learn this information.

Answering correctly demonstrates understanding of all the steps involved in moving speech between two people over an IP network in IP packets, using everything covered in the course.

Students receive course completion certificates at the end. Any students who choose to write the online CVA exam after class will also receive the TCO Certified VoIP Analyst certification.
