| POTS and The PSTN |
It all begins with Plain Ordinary Telephone Service and the Public Switched Telephone Network. In this course, you’ll build a solid understanding of the fundamentals of the telephone system: customer premise and Central Office, loops, trunks, remotes, circuit switching and how a telephone call is connected end-to-end. We’ll cover LECs and IXCs, sound, analog and the voiceband, twisted pair, DTMF and SS7.
Based on Teracom’s famous Course 101, tuned and refined over the course of 20 years of instructor-led training, we’ll cut through the jargon to demystify telephony and the telephone system, explaining the jargon and buzzwords, the underlying ideas, and how it all works together… in plain English.
Featuring many photos of actual equipment both inside a Central Office and in the outside plant, this multimedia course is an excellent way to get up to speed on traditional telephony.

| Wireless Telecommunications |
Wireless Communications is a comprehensive course on wireless, mobile telecommunications plus wireless LANs and satellites.
You'll gain a solid understanding of the key principles of wireless and mobile networks:
• Coverage, capacity and mobility
• Why cellular radio systems are used
• Mobile network components and operation
• Registration and handoffs
• Digital radio
• Data over cellular
• Cellular technologies and generations:
- 1G analog FDM
- 2G GSM and IS-136 TDMA
- 3G UMTS and 1X CDMA
- 4G LTE OFDM
Plus, you'll receive an overview of the radio frequencies and standards for wireless LANs and an overview of satellite communications.
The objective of this course is to develop a solid understanding of mobile communications networks and technologies. We'll cut through the jargon to demystify wireless, explaining the jargon and buzzwords, the network, technologies, the underlying ideas, and how it all works together... in plain English.

| The OSI Layers and Protocol Stacks |
This course begins the four "IP Telecom" courses in both the Certified Telecommunications Network Specialist (CTNS) and the Certified IP Telecom Network Specialist (CIPTS) certification packages.
This course establishes a framework for all of the discussions in subsequent lessons and courses: the OSI 7-Layer Reference Model, which identifies and divides the functions to be performed into groups called layers. This framework is required to sort out the many functions that need to be performed, and to be able to discuss separate issues separately.
You'll learn what a layer is, the purpose of each layer, see examples of protocols used to implement each layer, and learn how a protocol stack really works with the famous "FedEx Analogy" presented as an embedded video by our top instructor, Eric Coll.
Based on Teracom’s famous Course 101, tuned and refined over the course of 20 years of instructor-led training, we'll cut through the jargon to demystify layers, explaining the jargon and buzzwords, and most importantly, the underlying ideas, and how it all works together... in plain English.

| Ethernet, LANs and VLANs |
Ethernet LANs are the standard method of implementing Layer 2 of the OSI Model, data links between two machines.
Taking this course, you'll gain a solid understanding of LANs:
• Ethernet and its bus topology
• CSMA-CD access control
• Broadcast domains
• MAC addresses
• MAC frames
• The IEEE 802 standards
• Evolution of Ethernet from 10BASE-T to Gig-E
• Hubs and switches
• LAN cables
• The TIA-568 cable categories
• What "bridging" means
• How a LAN switch works
• VLANs
and finishing with a preview of the next course: using routers to move frames between broadcast domains.
We’ll cut through the jargon to demystify Ethernet, MAC addresses, LANs and VLANs, explaining the jargon and buzzwords, the underlying ideas, and how it all works together… in plain English.

| IP Networks, Routers and Addresses |
IP Networks, Routers and Addresses is a comprehensive course on Layer 3 of the OSI Model, concentrating on IP addresses, routers and packets.
First, we'll understand bandwidth on demand and its advantages over channelized TDM. Then we'll see how routers implement the network with packet-switching, that is, relaying packets from one circuit to another, and how routers are a point of control for network security. We'll introduce the term Customer Edge (CE), and understand the basic structure and content of a routing table.
Then we'll cover the many aspects of IP addressing – needed for the packet switching: IPv4 address classes, dotted decimal notation, static vs. dynamic addresses, DHCP, public vs. private addresses, Network Address Translation, and finish with an overview of IPv6 overview and IPv6 address allocation and assignment.
Based on Teracom’s famous Course 101, tuned and refined over the course of 20 years of instructor-led training, we’ll cut through the jargon to clearly explain IP and routers, packets and addresses, the underlying ideas, and how it all works together… in plain English.

| MPLS and Carrier Networks |
MPLS and Carrier Networks is a comprehensive training course designed to build a solid understanding of carrier packet networks and services, the terminology, technologies, configuration, operation and most importantly, the underlying ideas… in plain English.
This course can be taken by both those who need simply an overview and introduction to the fundamentals of carrier packet networks and MPLS, and by those who need to get up to speed and establish a solid base that project or job-specific knowledge can be built on.
We’ll cut through the buzzwords and marketing to demystify carrier packet networks and services, explaining Service Level Agreements, traffic profiles, virtual circuits, QoS, Class of Service, Differentiated Services, integration, convergence and aggregation, MPLS and other network technologies, and how they relate to TCP/IP without bogging down on details.
You will gain career- and productivity-enhancing knowledge of the structure, components and operation of carrier packet networks and services, how they are implemented, packaged and marketed by carriers and how they are used by government, business… and other carriers.
