Recent Developments and Trends in Telecommunications

Eight major developments and trends in telecom that you need to know about

Teracom’s training represents the core knowledge set required for the telecom business.  We’ve been teaching people the fundamentals of telecom and networking since 1992, so there have been many changes to the core knowledge set, and updates to our training over the years!

Check out Teracom’s best-of-breed training – with free tutorials!

For the new school year, we have updated our core training yet again, with some significant shifts. For example, Voice over IP is now part of the fundamentals, and channelized systems like T1 and SONET are now referred to as “legacy technologies” for the first time ever.

Here’s a summary of the recent developments and trends in telecommunications that triggered these updates:

1. All new phone systems are VoIP.  SIP trunking services replace PBX / PRI trunks from LECs.

2. Optical Ethernet has replaced SONET for all new core fiber network projects, and is also routinely used for “last mile” connections, achieving a long-held goal in telecommunications: one technology for all parts of the network.

3. MPLS has replaced ATM for traffic management on carrier networks, achieving another long-held goal: convergence and service integration… one network service, one access circuit, one bill for all telecom services.

4. 4G LTE has achieved the goal of a worldwide standard for mobile wireless.

5. “Data” on cellular plans means Internet access. It can be used for phone calls, video on demand, web surfing, real-time traffic on maps or any other application. Cellular data plans can be replaced with WiFi, which is often free.

6. Broadband carriers, also known as Cable TV companies, have evolved into telecom companies, gaining a majority share of residential Internet access in the USA, and providing services to business using both cable modems and fiber.

7. Telephone companies provide Cable TV service using Fiber to the Neighborhood and VDSL over loops in brownfields, and often Fiber to the Premise in greenfields.

8. In the future, the Internet and the telephone network will be the same thing. Basic telephone service will be “IP dial tone”: the ability to send an IP packet to any other point on the network. There will be no such thing as “long distance”.

To explore and understand these developments in more detail, while getting a firm grounding in the fundamentals and installed base…

“I really appreciated the telecommunications training course provided by Teracom Training Institute. I did learn a lot and understand things better, so that I am now able to tie everything together to understand all the facets of Telecommunications. Many of the acronyms, technologies, network designs and services – I would have no idea what they meant if it were not for this class. Thanks, I really enjoyed it.”

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.

Textbook now available on iTunes, Amazon Kindle and Google Play Books

Almost finished a 3.5-year-long project to get our training courses available online, last major milestone accomplished today with the companion reference textbook now available on iTunes, Amazon Kindle and Google Play Books.

Learning all the material in the book took 25 years.
Writing the book in Word took six months.
Putting it in Adobe inDesign to export it in EPUB format (eBook) took three months.

Amazon took 10 minutes to open an account and upload the book to Amazon kindle.
http://www.amazon.com/dp/B00F3KCDOS
You can read the book on pretty much any device
They take 70% commission and pay 30% to the author.

Google took a week to get the book uploaded and online on Google Play Books.

You can read the book on pretty much any device.
They take 30% commission and pay 70% to the author.
They put the book on sale at a reduced price, but still pay 70% of the list price to the author.

Apple took two weeks to get uploaded and online on iTunes iBooks.
https://itunes.apple.com/us/book/telecom-datacom-networking/id705339315?mt=11
You can only upload the book from an Apple computer. Not a PC, iPhone, iPad or iPod.
You can only read the book on iPhone, iPad or iPod touch. Not on any computer.
They take 30% commission and pay 70% to the author.
They put the book on sale at a reduced price, but only pay 70% of the sale price to the author.

Why did I put Amazon first on the list?? They keep all the money! Google Play seems the best, since it is both the cheapest and you can read the book on any device. But does anyone actually buy books on Google Play Books? iTunes of course has the most users and so maybe the most people will see it there. Time will tell…

Tutorial: MAC Addresses

What is a MAC address?

The term comes from the Institute of Electrical and Electronics Engineers (IEEE) 802 series of standards for LANs and MANs developed following the invention of Ethernet LANs by the Digital Equipment Corporation (now a part of HP), Xerox and Intel in 1979.

And people say Xerox never does anything original!

The first kind of LAN, Ethernet, employed a bus topology. The term bus comes from the Latin word omnibus, meaning “all”. It is used in electrical power systems, where a bus is a thick metal bar used to distribute electricity to many circuits.

Cisco VoIP phone vulnerability: continuously monitor and record all sound in people's offices, boardrooms and bedrooms

A recent report of a Cisco VoIP phone vulnerability is very disturbing.

http://www.networkworld.com/community/blog/cisco-issues-alert-voip-vulnerability

This is more serious than phone calls.

If the network world article is accurate, its first paragraph “vulnerability in its IP phones that allows hackers to access calls and call data” should read

“vulnerability in its IP phones that allows attackers to eavesdrop in people’s offices, boardrooms and bedrooms”

— or in fact, “continuously monitor and record all sound in people’s offices, boardrooms and bedrooms”.

EC circa 1998 – The big prize is video on demand replacing movie rental stores

The video clip above is me talking about The Future. Shot in 1998. I was 36. I came across this by accident on a tape I was re-using.

The same day I came across this by accident, today, fourteen years later, I am getting Bell Fibe TV installed, which is exactly what I was talking about in the video clip!

Broadband high-speed Internet service (25 Mb/s) with IPTV over DSL over the phone line for content delivery.

Spooky!
