Research and Markets: This E-Learning 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/c42453) has announced the addition of "E-Learning Course: Voice Switching" to their offering. "Voice Switching" provides an introduction to the principles and operation of circuit-switched telephony as used in the Public Switched Telephone Network (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. ). Fundamental issues that are also relevant to Voice over IP services are discussed. Introduction: Telephony is undergoing a revolution in the technologies used and the services provided. This course covers the principles of circuit-switched telephony. The course also covers subjects, such as teletraffic engineering and signalling, that are not only relevant to conventional telephone networks but also Voice over IP (VoIP) services. Course aim: This course provides an introduction to the principles and operation of circuit switched telephony as used in the Public Switched Telephone Network (PSTN). Pre-requisites: Secondary (high) school education in Physics. In the UK, appropriate pre-requisite qualifications are General Certificate of Secondary Education Noun 1. General Certificate of Secondary Education - the basic level of a subject taken in school GCSE, O level England - a division of the United Kingdom (GCSE GCSE 1.

They are practical qualifications based on being able to do a job. (NVQ NVQ n abbr (BRIT) (= national vocational qualification) → título de formación profesional NVQ n abbr (= National Vocational Qualification) → ) at level 2 in Electronics. "Voice Switching" 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. It 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 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 provides a structured assessed course and can also be used to browse for revision or reference. This 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 aimed at technical staff involved in the operation, installation or maintenance of systems that deliver telephony and/or video-based services. Course Content Introduction to the PSTN: Overview of the components and structure of the PSTN. Review of the functional elements of an exchange. Setting up a call over the PSTN. Numbering in the PSTN. Principles of signalling: Functions of signaling in a system providing a telephony service. The role of local and inter-exchange signaling Message exchange in call set-up and release for both a conventional call and a call involving the Intelligent Network (IN) Introduction to the concepts of Channel Associated Signalling (CAS) and Common Channel Signalling (CCS (1) (Common Channel Signaling) A communications system in which one channel is used for signaling and different channels are used for voice/data transmission. Signaling System 7 (SS7) is a CCS system, also known as CCS7. See SS7. ). Signalling in the local loop: Use of Channel Associated Signalling methods including loop/disconnect and DTMF (Dual-Tone MultiFrequency) The type of audio signals that are generated when you press the buttons on a touch-tone telephone. See also DMTF. DTMF - Dual Tone Multi Frequency Functional components of a telephone Role of audio information tones Provision of a Calling Line Identity (CLI (1) (Call Level Interface) A database programming interface from the SQL Access Group (SAG), an SQL membership organization. SAG's CLI is an attempt to standardize the SQL language for database access. ) service. Inter-exchange signalling: Use of Common Channel Signalling (CCS) between exchanges Benefits of the use of CCS Role of various types of signalling point in a signalling network Path diversity in the signalling network Types of CCS used in the PSTN, ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. and private networks Role of, and relationship between, the various protocols used by the common channel signalling system number 7 (C7) Role of signalling messages involved in call set-up. The Intelligent Network: Services provided by the Intelligent Network (IN) Role of, and interaction between, C7 signalling protocols in the IN including ISDN User Part (ISUP (ISDN User Part) See SS7. ) and IN Application Part (INAP (Intelligent Network Application Part) An IN (Intelligent Network) protocol used in a European SS7 network to query databases for a variety of functions not related to call setup and tear down. INAP uses the ASN.1 standard for defining message content. See SS7 and ASN.1. ) Provision of supplementary services including call forwarding Role of Service Control Point (SCP) Number translation procedure for non-geographic numbers. Teletraffic Engineering: Grade of Service The Erlang Blocking probability Relationship between blocking probability and the number of available circuits Erlang B and Erlang C formulae Availability Post Dial Delay The time between punching in the last digit of a telephone number and receiving a ring or busy signal. . Appendix: Information on older inter-exchange Channel Associated Signalling (CAS) systems no longer in use in modern networks including in-slot and out-of slot PCM signalling, in-band and out-of-band tone (R2) signalling and E & M signalling (not assessed).
