This Course Is Designed For Those Studying For A Career In Telecommunications And Who Require A Detailed Knowledge Of Telephony And Video Systems.DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c39043) has announced the addition of "E-Learning Course: Voice over IP" to their offering. "Voice over IP" provides an introduction to the principles and operation of telephony services that operate over Internet Protocol See Internet and TCP/IP. (networking) Internet Protocol - (IP) The network layer for the TCP/IP protocol suite widely used on Ethernet networks, defined in STD 5, RFC 791. IP is a connectionless, best-effort packet switching protocol. (IP) networks and includes detailed treatment of SIP and H.323. It is suggested that this course is studied with TRG TRG Training Group TRG The Resource Group TRG Technical Resource Group TRG Technical Review Group TRG Technology Research Group TRG Tory Reform Group TRG Tactical Reconnaissance Group TRG Training received (on overtime forms) "Advanced IP networks". Introduction: The provision of telephony over the same types of network that carry Internet traffic Internet traffic is the flow of data around the Internet. It includes web traffic, which is the amount of that data that is related to the World Wide Web, along with the traffic from other major uses of the Internet, such as electronic mail and peer-to-peer networks. is an increasingly important subject for the telecommunications industry. So-called Voice over IP (VoIP) services are likely to become as prevalent as conventional PSTN (Public Switched Telephone Network) The worldwide voice telephone network. Once only an analog system, the heart of most telephone networks today is all digital. In the U.S. services. This course aims to provide an introduction to the principles and operation of telephony services that operate over Internet Protocol (IP) networks. Pre-requisites: Understanding of issues relating to relating to relate prep → concernant relating to relate prep → bezüglich +gen, mit Bezug auf +acc the provision of a public telephone service including numbering, role of signalling and Grade of Service calculations. It is recommended that MediaNet course A: "Voice Switching" is studied before attempting this course. Also: understanding of the principles of operation of networks using IP. The e-learning course TransNet course F: "IP Networks" covers this topic. Although not a pre-requisite, the study of TransNet course G: "Advanced IP Networks" would also aid the understanding of the transmission aspects of a VoIP service. "Voice over IP" forms part of the MediaNet suite of courses. MediaNet is a suite of interactive, multimedia e-learning courses designed to run under Windows(TM) 2000 Professional or XP.It provides training in the technical aspects of delivering voice and video services and consists of three separate but integrated courses: A Voice switching B Voice over IP C C7 signalling Each MediaNet course provides several hours of in-depth, authoritative technical training.It also employs interactive simulations, hypertext links and question sessions to fully involve the trainee in the learning experience. This course provides personalised training with each trainee able to make his/her on notes and place bookmarks. A record of progress and level of achievement is recorded for each trainee. It also provides a structured assessed course and can also be used to browse for revision or reference. The course can be studied in isolation or as an integrated suite; each chapter of a course includes revision links to relevant subjects covered in the other MediaNet courses. Target audience: MediaNet is designed for those studying for a career in telecommunications and who require a detailed knowledge of telephony and video systems. It is also aimed at technical staff involved in the operation, installation or maintenance of systems that deliver telephony and/or video-based services. Course Content Contains: --VoIP packet transport: review of the advantages of a Voice over IP (VoIP) telephony service over that provided over a circuit-switched network --Voice encoding and bandwidth: processing of speech including PCM (1) See phase change memory. (2) (Plug Compatible Manufacturer) An organization that makes a computer or electronic device that is compatible with an existing machine. encoding, echo cancellation The elimination of an echo in a two-way voice transmission. Echo is created in the telephone company's central office switch when two-wire lines from the customer are converted to four-wire lines for backbone trunks. , compression and silence suppression Encoding the start and stop times of silence (lack of voice) in order to eliminate wasted bandwidth when sending voice over a packet-switched system. --Session Initiation Protocol (SIP): role of the functional components of a VoIP system using SIP including user agent, proxy server Also called a "proxy," it is a computer system or router that breaks the connection between sender and receiver. Functioning as a relay between client and server, proxy servers are used to help prevent an attacker from invading the private network. , location and redirect servers --H.323 VoIP systems: role of the various protocols involved in providing an H.323 audiovisual service inc. H.225, H.245, and the Real-time Protocol (RTP (1) (Rapid Transport Protocol) The protocol used in IBM's High Performance Routing (HPR) system. (2) (Realtime Transport Protocol) An IP protocol that supports real time transmission of voice and video. ) For more information visit http://www.researchandmarkets.com/reports/c39043 |
