	Teracom DVD Video V2 Fundamentals of Telecom 2 - preview Preview of Fundamentals of Telecom 2 COMPANY: Teracom Training Institute http://www.teracomtraining.com DATE: May 15 2007 TYPE: Tutorial, DVD URL: http://www.teracomtraining.com/teracom-overview-v2.htm RELEASE INFO: In this video course, we drill into the technology a bit, to understand the concepts, standards and technologies for actually transmitting voice calls from one place to another. We'll give you a real understanding of what "digital" actually means, and how it is implemented. We'll explain what a "DS0" is, and take a practical tour of digital circuits, including T1, T3, SONET and ISDN. At a high level, we'll see how voice, data and video can be integrated. Then, we'll take a closer look at how this is all actually done, with Time Division Multiplexing (TDM) and digital carrier systems that are the technologies at the heart of telecom networks. Without getting bogged down on technical details, we'll provide you with a basic understanding of how transmission systems work, including T1 over copper wires and SONET over fiber. Most of the transmission systems we have in place were designed for digital voice communications using these techniques... but they are also used for data and networking. This video course provides you with the concrete knowledge of the telecommunication circuits necessary to a full understanding of data circuits and network services.

	FTTH Fiber to The Home: Diginfo With 4.8 million subscribers in Japan alone, Fiber To The Home (FTTH) is the latest development in telecommunications networks. Optical Fiber is connected from the internet service provider directly to the home or office, consolidating services such as phone, television and internet into one communication medium. One of the main advantages of FTTH is that the system doesn't need external power sources or repeaters to transmit signals long distances, drastically reducing maintenance and ongoing costs for telecommunication companies.

	Phone Company Gives FBI Full Entry to All Customers Data 1/2 http://www.democracynow.org/ Telecom Whistleblower Discovers Circuit that Allows Access to All Systems on Wireless Carrier -- Phone Calls, Text Messages, Emails and More Babak Pasdar is a computer security expert who was hired in 2003 to help restructure the tech infrastructure at a major wireless telecommunications company. What he found shocked him. The company had set up a system that gave a third party, presumably a governmental entity, access to every communication coming through that company's infrastructure. This means every email, internet use, document transmission, video, text message, as well as the ability to listen to and record any phone call. http://www.democracynow.org/
	Poi Transmission: Spinning in Arizona This is my favorite video I've made for the web. It showcases four poi spinners (with some double-staff too) with some next-level moves and editing. More videos and higher quality can be found at www.InstrumentsOfTheNow.com Specifically, our interstellar poi communications are explorations into linear extensions/isolations, hybrids, cateyes, elliptical flowers, and composite spinning.

	net neutrality - not! traffic shaping and traffic policing When someone demands "net neutrality", they usually mean that the network must not discriminate between applications being carried in IP packets; that identical transmission characteristics (throughput, delay, number of errors, etc.) are to be provided for all packets regardless of what is being carried in them. They claim (correctly) that this is not the case at present, that the network service provider is "throttling" certain applications, "slowing down" or "shaping" traffic (the correct term is "policing") and that this, in their opinion, must stop. This video tutorial explains Service Level Agreements, traffic profiles, transmission characteristics, and how Differentiated Services (Diff-Serv) is implemented to be able to provide different transmission characteristics for different kinds of traffic - the EXACT OPPOSITE of net neutrality. It is taken from Teracom's DVD video V9 Understanding Voice over IP 2: Voice Packetization • Voice Quality • Codecs, Jitter and Packet Loss • Diff-Serv • Network QoS with MPLS

	Hackers Planning To Steal Election For McCain Tuesday, September 30, 2008 Stephen Spoonamore warns in a new interview that electronic voting machines represent a national security threat and that hackers are already planning to steal the 2008 presidential election for John McCain. Spoonamore is a GOP member and a lifelong Republican, having worked on election campaigns with Rudy Giuliani and Michael Bloomberg. He also has 20 years worth of experience in encrypted and networked communications systems for banks, TV, telecommunications, EMS, Military and other uses. In an ten part You Tube interview, Spoonamore warns that hackers are planning to steal the election on behalf of the McCain camp and even predicts the margin of victory, that McCain will make a shocking recovery and win 51.2 percent of the vote with three electoral votes over Obama. This is a national security threat, said Spoonamore, it is very possible for a foreign government to begin manipulating that transmission of code just as they attempt to do fairly often with our financial data.we deal with it every day on the commercial side, he added, noting that China, and not the American people, has a greater chance of choosing the next U.S. president. Spoonamore also fingered Israel as another foreign government that was planning to attempt to hack the 2008 election. We dont know whos changing the vote now - these weird results are coming in all over, said Spoonamore, adding that the danger of the vote being hacked by Israel, China or Russia is an even greater threat than partisan vote fraud on behalf of the Democrats and Republicans. Youve built a vulnerable system and many people would want to exploit that vulnerability and not all of them have the best interests of our nation at heart, he added. In the interview, Spoonamore stresses how easy it is to hack an electronic voting machine and rig an election. If people think that a voting machine that calls in to a tabulator is any different than all those cash registers calling in to the central processor - its the same thing, said Spoonamore. If you put a man in the middle attack, a computer sitting in the middle that can change or capture or manipulate the information, it will do so, he added. Its valuable to be president.if you can steal it for a couple of million bucks why not, said Spoonamore, adding that the last two presidential elections were stolen. Spoonamore said that he had personally witnessed people attempting to hack election systems and since going public with his testimony had received threats not to talk about vote fraud because it would undermine Americans confidence in the voting process, to which Spoonamore responded that people should doubt their vote because its being stolen. Spoonamore said that top Republican operatives had told him that election hacking was just a different methodology but they didnt grasp the fact that if you build a hackable system, theres hundreds of sharks that want to hack it and you will not know who the final hacker was. Spoonamore said that the only way to prevent elections being stolen is a complete return to paper ballots, a move back to what worked so well for 190 years, and the elimination of electronic voting machines. http://www.prisonplanet.com
