Demystify Buzzwords And Jargon

One of the biggest challenges in telecommunications is all of the acronyms, abbreviations, jargon and buzzwords.

The list goes on and on: POTS, PSTN, loops, trunks, VoIP, SIP trunking, Hosted PBX, DSL, DS1, T1, PRI, ILEC, CLEC, POP, MAN, TDMA, CDMA, LAN, WAN, Ethernet, MAC address, MAC frame, IP packet, TCP/IP, OSI, Layer 2, Layer 3, VLAN, TDM, DWDM, FTTN, FTTH, FTTP, DHCP, NAT, MPLS, VPN, SLA, ISP, DNS …

Plus, there is a second-order problem: even if you were to figure out all of the current jargon and buzzwords, it’s certain that new ones will be invented next month!

It can be very frustrating sitting in meetings with these terms flying around and not understanding most of them… particularly when someone asks your opinion.

So the question is: how to get on top of all the jargon and buzzwords, knowing that there is going to be constant change?

Our answer: understand the fundamentals. Take the cover off the box and understand how it works. Once we do this, we discover that there are only a few main ideas in telecom technology, with incremental improvement in each area.

Taking this course and understanding the fundamental ideas puts you back in control, with the confidence to contribute effectively. Even if you don’t know the exact details of a product someone is discussing, you will still know what they are talking about.

Understand The Network Cloud

People like to draw a diagram of a network as a cloud with sticks poking into it, and refer to the network as “The Cloud”. This might be useful for drawing diagrams, but if you are using, planning, ordering, managing, troubleshooting, developing software for or otherwise involved with telecom circuits and services, understanding what’s inside is productivity- and career-enhancing knowledge.

In this course, you will learn how circuits and services are actually provided, giving you the knowledge to make meaningful comparisons and accurate decisions.

We’ll explore every different aspect of The Cloud:

  • The fundamental structure of the network: access, switching and transmission;
  • The companies that physically implement the network: ILECs, CLECs, IXCs, how and where they interconnect, and
  • The components of a service: access circuit technology, network service type and billing plan;
  • The equipment used: switches, routers, multiplexers, fiber and modems;
  • How users share the network: channels, packets and Service Levels.

Gain Vendor-Independent Knowledge You Can Build On

The knowledge you gain taking this training course is vendor-independent foundational knowledge in telecommunications.

You will be able to build on this proven knowledge base to quickly get up to speed for a particular project – then have the versatility to work on subsequent projects.

The cost of this training will be repaid in productivity gain many times over.

Based on Teracom’s proven instructor-led training courses developed and refined over twenty years providing training for organizations including AT&T, Verizon, Bell Canada, Intel, Microsoft, Cisco, Qualcomm, the CIA, NSA, IRS, FAA, US Army, Navy, Marines and Air Force and hundreds of others, Teracom online courses are top-notch, top-quality and right up to date with the topics and knowledge you need.

Course 101 Content and Schedule Update

Our famous instructor-led training Course 101 “Telecom, Datacom and Networking for Non-Engineering Professionals” covers the key knowledge set required in the telecom business… so must be updated regularly.When the course was first written 20 years ago, the Internet did not exist. In the lastest update, the basics of Voice over IP are in the “Fundamentals of Telephony” chapter!

To quote Loretta Lynn: We’ve come a long way, baby!

Check out the new outline.

The latest edition reflects how “convergence” has finally been achieved by treating voice and video like data, in IP packets.

VoIP is promoted to “fundamentals”, channelized TDM and SONET is demoted to “legacy technology”, replaced with IP/Ethernet backbones. Other updates include fiber to the home, and VDSL and DOCSIS 3.1 for the last mile.

As always, our goal is to bust the buzzwords, demystify jargon, understand technologies and mainstream solutions and – most importantly – the ideas underlying all of this, and how it all works together, in plain English … knowledge you can’t get on the job, talking to vendors or reading articles.

How ISPs connect to the Internet: peering vs. transit

This discussion is covered in Course 101, Chapter 16 “Understanding the Internet”,
and in more depth in Course 110, Chapter 16 “IP as a Business: Carrier Networks, Competition and Interconnect”

Originally, the only way to get on to the Internet was from a terminal connected to a computer at a university or research institute. The Internet was mostly circuits paid for by the taxpayers via the National Science Foundation. Today, commercial Internet access providers, called Internet Service Providers (ISPs) provide the capability for anyone to access and communicate over on the Internet. These ISPs are for the most part business units of facilities-based carriers, i.e. telephone companies and cable companies.

Such service providers have physical access circuits and circuit-terminating equipment on the customer side, plus routers, security and access control equipment to manage customer traffic. This is often organized with data centers in cities or regions, which are interconnected. This ensemble of interconnected routers controlled by an ISP is called an Autonomous System (AS).

The Internet is a vast, unregulated collection of interconnected Autonomous Systems. The connections between ASs are not specified by a central authority or world government, but are implemented on a case-by-case basis by the operators of an AS for business reasons. The Internet is not free. It is not a public utility. It is a business.

ISPs operating ASs will connect to competitors and content providers like Google to exchange traffic terminating on each other’s network (called peering), and will connect to larger organizations who will assure delivery of packets to other destinations (transit). The networks are physically connected at Internet Exchange (IX) centers such as Equinix Chicago at 350 E Cermak. These are buildings with equipment implementing network interconnection operated by a neutral third party. The ASs are responsible for paying for connectivity to the IX.

Course 101, page 16.09: Internet Service Providers

Internet Service Providers

Peering is settlement-free, i.e. no money is exchanged. Transit is a commercial service that costs money. Larger ISPs charge smaller ISPs for transit services. The largest networks are sometimes called Tier-1 service providers… but “Tier-1” is not an officially defined term. Some claim that it means a network “close to the center of the Internet” or a network that does not pay for transit. However, there is no “center” to the Internet, and virtually all networks employ a mix of peering and transit agreements to connect to other networks… and the nature of such connections is non-disclosed confidential business information. A “Tier-1 network” might best be thought of as one operated by a very big facilities-based carrier that has presence in most or all IXs and sells transit services to smaller networks and ISPs.

The ISPs build the access network and peering or transit connections to other networks, then charge the users for access. It’s a pyramid scheme. The end users end up paying for all.

In addition to access services, the ISP usually provides a Web server to host your website, a Domain Name Server, and an e-mail server.
Back in the Flintstones era when dial-up Internet access was first available, telcos were a bit slow to react, so for a while, companies like Netcom, MindSpring, Portal, Pipeline, iStar and others had their day in the sun. These organizations were resellers, leasing circuits from a carrier and reselling them to users under per-minute or per-month billing plans.

The carriers eventually began competing with resellers, who for the most part went out of business, selling their customers to the carriers. For example, Netcom is now part of Earthlink, which is majority owned by Sprint. AOL and MSN are the biggest remaining reseller-type ISPs. For the most part, it is business units of the companies that own the cables coming into your home: the LEC and the cable TV company that are the dominant ISPs today.

If you do choose to use a reseller-type ISP, particularly for a business or organization, questions regarding customer service, capacity and availability should be asked. Another is redundancy – do they have a single point of failure? Do they have multiple connections to different Tier-1 providers? What capacity are those connections?
