Who Should Attend

Who Should Attend

Teracom’s training is geared towards non-engineers who work for:
• Telecom network and service providers including telephone companies, fiber backbone companies, broadband (cable) companies, mobile companies, CLECs and aggregators and resellers,
• Telecom equipment manufacturers including manufacturers of CO equipment, switches and routers, fiber and wireless transmission systems, handsets and last-mile technologies,
• Organizations that buy telecom equipment and services, including banks, power companies, government and military… including the telecom department of Wells Fargo, Entergy, the Justice Department, the US Marines, Oneida Tableware, the SF Giants and Portland Trailblazers amongst many, many others.
… and individuals who would like to improve their skills for this kind of job.
“Non-engineering personnel” means professional personnel:
• whose primary functions include accounting, tax, finance, business development, planning, marketing, sales, operations, telecom help-desk support, telecom service ordering and auditing, and software development,
• who are required to deal with telecommunications network technologies in their job,
• who have not had formal training on the telecom network and its related technical jargon, acronyms, abbreviations and technologies.
• who experiences frustration at not understanding all the technical terms and how everything fits together, has learned bits and pieces on the job, and is at risk of being inefficient or even making errors in their job because of it.
“Training for non-engineers” means that the training is at the concept level, understanding the key ideas and mainstream practices, and don’t get into detailed design discussions. For example, we discuss the ideas behind SIP, what it is and it works, but don’t analyze SIP message packets.
An exception to the “non-engineers” audience is engineers who are not telecom engineers. We have trained many software engineers and developers, who are tasked with developing provisioning, operations or billing systems for telecom services – but who have little or no knowledge of the “network”, and will benefit from understanding the application for the software they are developing. We also see mechanical, chemical and civil engineers who have ended up working for a telecom company and need to fill in gaps.

Our Instructors

Our Instructors

Teracom’s instructors are professionals with broad and deep knowledge of telecommunications, data communications and networking technologies and trends and many years’ experience teaching seminars.
Unlike some you will encounter elsewhere, Teracom instructors all have Engineering or equivalent university degrees and hands-on experience working with the technologies they’re teaching.
All of our instructors share another common trait: the ability to cut through the jargon and buzzwords to explain the key concepts and mainstream solutions in plain English, without bogging down on jargon… knowledge you can’t get by reading trade magazines or talking to vendors.

Instructor-led training is the best you can get, as it allows you to focus, to interact and ask questions. Online courses are available anytime, anywhere, and the certification is concrete proof of knowledge acquisition. DVD-video courses are useful for group training. Textbooks can be used on their own, and many people find the textbooks an invaluable companion to instructor-led, online or DVD courses.
Online courses and certification are included as a free bonus with instructor-led training and DVD-video course packages.

How We Keep Our Training Up to Date

How We Keep Our Training Up to Date

The short answer: by constantly teaching public and private seminars.
The world of telecommunications has two aspects: the fundamentals, which change slowly, and the technologies, which change at a more rapid pace.
The content, the selection of topics, their order, the timing and pacing of our training courses has been tuned and refined over the years, based on our knowledge of the industry, experience working in the telecom business, and feedback from customers.
The content is kept up to date based on questions and feedback from seminar participants, and based on the set of topics requested for private onsite courses.
We count all of the biggest telephone companies in North America amongst our customers, and the topics they request for training each year are a driver of course updates.
Our flagship instructor-led course, which we think of as “core training”, i.e. the knowledge set needed by anyone serious in the telecom business, is updated approximately twice a year.
This helps ensure that our other training products: online courses, DVD-video courses and textbooks, which are for the most part derived from the instructor-led course, also stay up to date.

Tutorial: How do IP packets and MAC Frames go together?

It is important to understand how packets and frames are related, and in particular, IP packets vs. Ethernet or MAC frames.

Simple network example. Routers move packets from one circuit to another.

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.

Packet with its IP address vs. frame and its MAC address

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.
