“Awesome course, really. Just very, very good.”
– Tim Wilson, Ciena
“Thank you guys so much, this class was amazing! I would take this all over again!”
– Austin Thompson, NHC
“Since I am very new to telecom, this helped me connect the dots, the different layers and terminology. I liked that it followed the printed workbooks very closely so I could read the summaries after the lessons. The instructor was great. He kept it light, added some jokes to keep it entertaining. I liked most when he did drawings with his explanations.”
– Ashley Brinkman, Marketing Manager, MTA, Palmer Alaska
“The course was very beneficial for me. I wish I would have been able to take this class a few years back when I first started!”
– Tamara Pepin, CRTC
“I had some of the basics; this class filled gaps and added much more depth. Instructor Richard was open to questions at any time, and revisited topics until we got it. Having the notes in the printed course book to follow along and add to was very helpful. Richard was very passionate about the course material and had great real-life examples.”
– Robert Smieszny, NHC

Dear [Manager]
I need to get training on telecom to do my job effectively, and to that end, I would like to request permission to register for Teracom Training Institute’s Live Online telecom BOOT CAMP seminar the week of May 3-7.
www.teracomtraining.com/boot-camp.htm
detailed outline: www.teracomtraining.com/courses/teracom-brochure-course-111.pdf
course listing: www.teracomtraining.com/public_seminars.htm#LO
Teracom Training Institute specializes in telecommunications training for non-engineering professionals, which is exactly what I need.
I need this training because I have learned some things technology-wise “on the job”; but am frustrated by gaps in my knowledge, especially when people start speaking in jargon and buzzwords. Not being up to speed on it all is unproductive, frustrating and a bit awkward.
This training will improve my productivity, accuracy and efficiency… and enable me to contribute a lot more, having a knowledge base in the technologies and the jargon.
Being part of a live online class will keep me away from distractions, so I can concentrate and learn what I need. Instructor-led training is how I learn best. Plus, the high-quality detailed course books they will ship directly to me before the course will be good references going forward.
Teracom is the leader in this kind of training… type “telecommunications training” into Google and Teracom Training Institute comes up #1 in the search results. They’ve been doing this since 1992, and by all accounts are very good at it… virtually all of their ratings on Google are 5 stars: https://g.page/teracomtraining. They have a GSA contract for this training, which means they have been thoroughly vetted.
One thing that I like about Teracom’s BOOT CAMP is that it is totally up-to-date, starting with broadband and IP telecom network fundamentals, cloud computing and data centers, LTE and 5G, Optical Ethernet, VoIP, SIP trunking and IoT, plus a module on security.
Here is the five-day outline:
Day 1: Fundamentals, Cloud Computing and Data Centers
Day 2: Wireless, Fiber and Copper; Equipment and Carriers
Day 3: IP Networking and addresses plus MPLS, SLAs and Class of Service Guarantees
Day 4: VoIP and SIP: Fundamentals and Technologies, Softswitch as a Service
Day 5: Security, 5G and IoT
It comes with two course books printed in color shipped directly to me.
As a bonus, three TCO Certification Packages: CTNS, CVA and CTA are included, along with their courses and certification exams. There are no time limits or expiration dates on the bonus online courses.
This is the training I need. It will give me a solid base, fill in gaps and get me up to speed on the jargon, technologies and standard practices across the board.
Besides alleviating the frustrating jargon and buzzwords situation, it makes good business sense for me to attend. This training will make me more accurate – understanding the big picture, the ensemble of technologies and how they relate – and this can only make me (and therefore you) more productive and save the organization money.
The in-class discussions and case studies are also an excellent opportunity for me to discuss the general outlines of our situation and find out what others are doing.
The tuition is only $1895 for five days of professional training. I checked around and found other companies like Global Knowledge charge double or more for similar week-long courses, without the included online courses and certifications, and without the printed books.
There is an optional companion reference textbook at $89 I’d like to get as well.
Please let me know if I can get this training.
Thank you,

Course 2213 IP Addresses, Packets and Routers
Lesson 1 – Introduction to IP Addresses, Packets and Routers
Course 2213 IP Addresses, Packets and Routers
IP Addresses • Packets • Networks • Routers • Static and Dynamic Addresses • DHCP • Public and Private Addresses • NAT • IPv6
IP Networks, Routers and Addresses is a comprehensive course on IP networking fundamentals: IP packets, IP addressing and IP routers.
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: IPv4 address classes, dotted decimal, static vs. dynamic addresses, DHCP, public vs. private addresses, Network Address Translation, and finish with an overview of IPv6.
Course Lessons
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.
New Course 2241 Introduction to Broadband Telecommunications along with existing Course 2221 Fundamentals of Voice over IP will be added to the CTNS Certification Package before year-end.
The price of the CTNS package will increase when the number of courses increases from six to eight. Since all existing customers will automatically get the two new courses at no additional charge, you can beat the price increase by purchasing CTNS before the upgrade and get the two new courses, when they are released, for free!
It is important to understand how packets and frames are related, and in particular, IP packets vs. Ethernet or MAC frames.
Packets are for networks. A packet is a block of user data, such as a piece of an e-mail message, with a network address on the front. The network address is the final destination. The standard for network addresses is IP.
Network equipment like routers receive an IP packet on an incoming circuit, examine the indicated destination IP address, use it to make a route decision, then implement the decision by forwarding the packet to the next router, on a different circuit.
A frame is a lower-level idea. Frames are used to communicate between stations on the same circuit. The circuit may have multiple stations physically connected onto it, like a wireless LAN, a few stations connected by a LAN switch, or only two stations like a point-to-point LAN cable. Each station has a Media Access Control (MAC) address, sometimes called a hardware address, link address or Layer 2 address.
A frame has framing to mark the beginning and end, sender and receiver MAC addresses to indicate the stations on the circuit, control information, a payload and an error detection mechanism.
The frame is transmitted on the circuit, and all stations on the circuit receive it. If an error is detected at a receiving station, the frame is discarded and might have to be retransmitted somehow.
If no errors are detected, the receiver compares the destination MAC address on the received frame to its own MAC address, and if they are the same, processes the frame, extracting the data payload and passing it to higher level software on the receiver.
If the MAC addresses are not the same, the receiver ignores it and waits for the next one.
The end result is that the payload in the frame is communicated to the correct station on the same circuit, with no errors.
The main purpose of packets is to append an IP address to your data. The IP address is used by network equipment to make route decisions: to relay the packet from one circuit to a different circuit. This is accomplished by receiving the packet then transmitting it to a different machine, usually the next router in the chain.
To actually transmit a packet to another router, the packet is inserted as the payload in a frame, then the frame is broadcast on the circuit that connects to the next router.
Notice that there are two addresses: the IP network address and the MAC address.
The IP address on the packet is the final destination, and so does not change. The MAC address on the frame indicates the destination on the current circuit, and so is changed as the data is forwarded from one circuit to another.

This diagram provides a very high-level block diagram view of the processes involved in communicating speech in IP packets from one person to another:
Starting on the left, commands from the speaker’s brain cause combinations of lungs, diaphragm, vocal cords, tongue, jaw and lips to form sounds.
A microphone is positioned in front of the mouth and acts as a transducer, creating a fluctuating voltage which is an analog or representation of the sound pressure waves coming out of the speaker’s throat.
This is fed into a codec, which digitizes the voltage analog by taking samples of it 8,000 times per second and coding the value of sample into binary 1s and 0s. Typically, the value of each sample is represented with a byte, meaning 64 kb/s to be transmitted.
Approximately 20 ms worth of coded speech is taken as a segment and placed or encapsulated in an IP packet.
The IP packet begins with a header, which is control information, the most interesting part being the IP address of the source telephone and IP address of the destination telephone.
IP packets are moved from the source to the destination over a sequence of links.
The links are connected with routers, which relay the packets from one link to the next.
Lower level functions such as framing and link addressing are usually performed following the IEEE Ethernet and MAC standards.
At the lowest level, the links are physcially implemented with Category 6 LAN cables, DSL modems, Cable modems, fiber optics and radio systems.
At the destination, the bits are extracted from the IP packet and fed into a codec, which re-creates the analog voltage.
This voltage drives a speaker, which re-creates the sound pressure waves, which travel down the ear canal to the inner ear, causing hairs on the cochlea to vibrate, triggering neural impulses to the brain, making the listener think they are hearing something.
– – –
It’s important to note that the voice packets are communicated directly from one telephone to the other over the IP network.
The packets do not pass through a CO telephone switch, for example.
