I have done three certifications with Teracom (CIPTS, CWA, CTNS). The content of all three courses was excellent as it also covered the reasons for technological changes and evolutions. Since I work in the IT industry on the project management side for many years these courses were a perfect complement to my overall IT knowledge. I can now speak to engineers and technicians more on the same frequency and can provide better consultancy to my customers. I feel the courses are also priced fairly and are fun to watch and study.

Course 2211 Ethernet, LANs and VLANs
MAC Addresses • 802.3 and Ethernet • Broadcast Domains • LAN Cables • Switches • VLANs
Ethernet is the standard method of implementing data links between two machines. What started out as connections between PCs in the office has now spread to Optical Ethernet, used almost universally in the telecom network core, and fiber to the premise.
Course Lessons
1. Introduction
2. Buses, MAC Addresses and Frames
3. Ethernet and 802.3
4. Gigabit and Optical Ethernet
5. LAN Cables & TIA-568 Categories
6. Bridging
7. LAN Switches
8. VLANs
Based on Teracom's famous Course 101, tuned and refined over the course of more than 25 years of instructor-led training and counting. 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.
In this course, we'll examine technologies for connecting machines, called LANs.
Originally, devices were connected to a cable to form a LAN segment. Today, devices are connected to an Ethernet Switch, a.k.a. Layer 2 or LAN switch.
This technology, frames, MAC addresses, broadcast domains and VLANs, migrated from in-building applications to the telecom network. Carriers' networks are today built with point-to-point fiber connecting Layer 2 switches in different buildings.
Fulfilling the goal to use the same technology for access circuits and services as in the core of the network, LAN technology is now used for 40 Gigabit/sec service using Optical Ethernet to large office buildings and 10+ Mb/s fiber-based services to businesses.

This course could also be called "Layer 3", as it is all about Layer 3 of the OSI model: the network layer, and in particular, IP packet networks.
Packet networks embody two main ideas: bandwidth on demand and packet switching.
First, we'll recap channelized TDM and its limitations, then understand statistical TDM or bandwidth on demand.
Next, we'll understand 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 to be able to do 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 and IPv6 address allocation and assignment.

* Lessons on these legacy technologies are optional, included for reference for anyone who needs to know about them. They are not on the final exam. Feel free to skip these lessons.
Based on Teracom's famous Course 101, tuned and refined over the course of over 25 years of instructor-led training, 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.
MPLS and Carrier Networks is a comprehensive, up-to-date course on the networks companies like AT&T build and operate, how they are implemented, the services they offer, and how customers connect to the network.
This course can be taken by those who need just an introduction to carrier networks and MPLS, as well as by those who need to build a solid base on which to build project- or environment-specific knowledge.
In the previous course, we used a private network, i.e. dedicated point-to-point circuits connected with routers, as the simplest framework for understanding packets, bandwidth on demand, routers, and network addresses.
In this course, we will take the same idea and apply it again at the carrier network level: replacing the dedicated lines with bandwidth on demand service from a carrier between the customer locations.
We'll spend much of this course understanding a powerful traffic management tool called virtual circuits, how they are implemented with MPLS, and how MPLS can be used to provide differentiated services, aggregate traffic and implement convergence.
