Make Sense of X25 Data Services with New E-Learning Course.DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c42975) has announced the addition of E-Learning Course: X25 Data Services to their offering "X25 Data Services" discusses the protocols and techniques used in an X25 data service. Typical X25 service offerings are also described. Course aim: This course provides an introduction to the principles, operation and features of data services conforming to the ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. X25 recommendations. Pre-requisites: Understanding of the basic principles of packet switching A network technology that breaks up a message into small packets for transmission. Unlike circuit switching, which requires the establishment of a dedicated point-to-point connection, each packet in a packet-switched network contains a destination address. . It is recommended that TransNet course A - Principles of Wide Area Networks - is studied before attempting this course. "X25 Data Services" forms part of the TransNet series of courses. TransNet - is a suite of interactive, multimedia e-learning courses designed to run under Windows[TM] 98, 2000 Professional or XP. - provides training in the technical aspects of Wide Area Networks and data services. - consists of eight separate but integrated courses: A Principles of Wide Area Networks B X25 data services C Frame Relay data services D Principles of ATM E ATM networks F IP networks G Advanced IP networks inc. voice over IP H DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary services Each TransNet course: - provides several hours of in-depth, authoritative technical training - employs interactive simulations, hypertext links and question sessions to fully involve the trainee in the learning experience. - 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. - provides a structured assessed course and can also be used to browse for revision or reference. - 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 TransNet courses. Target audience: TransNet is designed for: - Those studying for a career in telecommunications and who require a detailed knowledge of modern Wide Area Networks and data services. - Technical staff involved in the operation, design or maintenance of Wide Area Networks.
