Understand the Principles and Capabilities of DSL with New E-Learning Course.DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c43661) has announced the addition of E-Learning Course: DSL Services to their offering. "DSL Services" is intended for technical staff involved in the planning, provisioning, maintenance and testing of Digital Subscriber Line See DSL. (communications, protocol) Digital Subscriber Line - (DSL, or Digital Subscriber Loop, xDSL - see below) A family of digital telecommunications protocols designed to allow high speed data communication over the existing copper telephone lines between end-users and (DSL) broadband connections. Topics covered include the principles and capabilities of ADSL and SHDSL SHDSL Single-Line High-bit-rate Digital Subscriber Line SHDSL Symmetrical High-Density Digital Subscriber Line SHDSL Symmetrical High Bitrate Digital Subscriber Line (Ericsson) SHDSL Symmetrical Highspeed Digital Subscriber Loop , the role of system components inc. the DSLAM (DSL Access Multiplexor) A central office (CO) device for ADSL service that intermixes voice traffic and DSL traffic onto a customer's DSL line. It also separates incoming phone and data signals and directs them onto the appropriate carrier's network. See DSL. and the B-RAS B-RAS Broadband-Remote Access Server , the use of ATM and PPP (Point-to-Point Protocol) The most popular method for transporting IP packets over a serial link between the user and the ISP. Developed in 1994 by the IETF and superseding the SLIP protocol, PPP establishes the session between the user's computer and the ISP using in DSL service provision, and the testing of DSL systems. Course aim: This course describes the theory, operation, components and features of systems providing ADSL and SDSL services. Pre-requisites: Understanding of basic datacoms principles and the use and operation of the Internet Protocol (IP). It is recommended that the "Ethernet Networks" e-learning course and the "IP Networks and the Internet" course in the TransNet suite are studied before attempting this course. "DSL 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 services 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. Course Content: Digital access over the last mile: Exploiting the existing telephone local access network to provide broadband Internet access Broadband Internet access, often shortened to just "broadband", is high speed Internet access—typically contrasted with dial-up access over modem. Dial-up modems are generally only capable of a maximum bitrate of 56 kbit/s (kilobits per second) and require the full use of a structure and components of the local access network using different frequency bands for voice and data summary of the different types of DSL service. Loop impairments: Source and effects of the various impairments on the last mile that limit the performance of DSL services including loss, crosstalk, external interference, bridged taps and loading coils. Signal processing: Principles of the signal processing techniques used by DSL services including 2B1Q and PAM-16 line codes, PSK and QAM modulation, and error correction. ADSL principles and services: Principles of DMT See DSL. as employed in ADSL systems simultaneous provision of a telephone service and an ADSL service over a single pair basic functions of an ADSL Termination Unit (ATU-R See ATU. ) differences between a full rate ADSL service and an ADSL Lite service enhanced features of ADSL2 and ADSL2 Plus. ADSL connections: Role of DSLAM and B-RAS equipment in an access network review of the features and benefits of an ATM network use of virtual channel connections role of the PPP protocol and authentication servers allocation of IP addresses to customers equipment operation of a simple bridged Ethernet ADSL connection principles and benefits of PPPoE and PPPoA connections. ADSL customer's equipment: Overview of various types of customers' equipment including ADSL modems, ADSL enabled routers, wireless routers use and comparison of splitters and microfilters review of security aspects of an ADSL service. Symmetrical DSL service: Operation and the features of a Single pair High speed DSL (SHDSL) service benefits of the use of TC-PAM TC-PAM Trellis Coded Pulse Amplitude Modulation modulation and error correction format and payload capability of an SHDSL frame use of an Integrated Access Device An IAD is a customer premises device that provides access to wide area networks and the Internet. Specifically, it aggregates multiple channels of information including voice and data across a single shared access link to a carrier or service provider PoP (Point of Presence). for the simultaneous transmission of voice and data. Testing DSL connections: Tests discussed include AC and DC line tests, Time Domain Reflectometer (hardware, networking) Time Domain Reflectometer - (TDR) An electronic device for detecting and locating short- or open-circuits in an Ethernet cable. TDRs can also measure how the characteristic impedance of a line varies along its length. tests insertion loss and noise measurement, ATM and IP end-to-end tests.
