Page _ 5 </p><p>1. Overview </p><p>1.1. Company profile </p><p> A leading worldwide telecommunication product and solution provider, established in 1988 in Shenzhen P.R.China, it had activity at national level and started signing contracts abroad at overseas level fewer years later. Today, Huawei Technologies is trusted by a number of leading telecom operators around the world, employing over 50 000 among which 40% are involved in Research &amp; Development. Huawei Technologies has notable achievements in Europe in the 5 last years, having been a leading partner for most of the European telecom operators, notably: </p><p> Approved Global UMTS supplier of Vodafone in Italy and Spain, including ODM handsets... </p><p> Preferred Supplier of British Telecom 21st Century Network since 2005, </p><p>including MSAN and Optical Transmission products (LH-DWDM). </p><p> Global cooperation with Telefonica on Mobile and Fixed/Broadband, and major IP DSLAM vendor. </p><p> Global Mobile Softswitch &amp; GSM BSS Supplier for Orange 2G/3G Networks </p><p> Sole supplier for 2G/3G Mobile Softswitch for KPN (), and main supplier for </p><p>Optical Transmission and NG IP DSLAM in ALL IP Project </p><p> IMS supplier of Deutsche Telekom network for T-COM &amp; T-Mobile networks in Hungary </p></li><li><p>International Master in Communication Networks Engineering 2nd Edition 2006/2007 Project work thesis: DWDM Networking </p><p>____________________________________________________________________________ Project work: SDH &amp; DWDM Networking * Huawei Technologies Italy (June-October 2007) By Tarek Belghith.

University presentation The Scuola Superiore Sant'Anna University is a public institution with special status, which works in the field of applied science: Economic Sciences, Education Law, Political Science, Agricultural Sciences, Medical Sciences and Industrial Engineering and Information. The school has the objective innovative pathways in research and training by getting through research and education at international level. Lecturers and researchers live and interact with the students every day, in a continuous cultural and intellectual exchange. Hence innovative ideas, the researches are developed in collaboration with universities, institutions, companies and research institutes abroad. Thanks to its international character, training of excellence and to the scientific community, the Scuola Superiore Sant'Anna has established itself as a point of reference in Italy and abroad. Among these international programs, we find the IMCNE International Master in Communication Networks Engineering held with Tunisian Universities. It started in October 2005, involving skilled students year after year to enhance their technical and scientific background in the field of Communication Networks and Information Technology. </p><p>1.3. Master and Convention This master program is scheduled to the students in two parts: The first is a theory part (8 months) that consists in an educational way </p><p>including course modules to be attended according to a given timetable, as well as practices, lab sessions and mini-project works relating to each module. The final evaluation is decided most of the times by a final exam. Most of these courses have been carried out in the Building of Scuola Superiore SantAnna in the Integrated Research Centre CNR (Via Moruzzi, Pisa, Italy). Some of the other courses took place in other facilities, such as the SantAnna Valdera Pole in Pontedera, the Interdepartmental Language Center CLI in Pisa. </p><p> The second is the practical part ( 4 months) that consists in a project work that the student performs during a stage period, a working period or a research activity to apply a part of his skills in a project that may relate to the scope of the master program, and thus, to validate his IMCNE masters degree. </p><p> I made my validation period in Huawei Technologies Company, Italy branch, working on the design and the technical study of some optical transmission networking projects for operators. </p></li><li><p>International Master in Communication Networks Engineering 2nd Edition 2006/2007 Project work thesis: DWDM Networking </p><p>____________________________________________________________________________ Project work: SDH &amp; DWDM Networking * Huawei Technologies Italy (June-October 2007) By Tarek Belghith. Page _ 7 </p><p>1.4. Project work During my practice period in Huawei Technologies Italy, I was assigned to deal with network design within the product team in the optical department of Huawei Technologies Italy in the office headquartered in Rome. In my project period, my work consisted on 2 main tasks: the first is WDM network design for an Italian telecommunication group that I will name OPERATOR X in this document, and which is a technical study of an optical transmission backbone through the country territory using the Huaweis BWS 1600G as OTM/OADM stations. The second was an elaboration of a technical SDH technology configuration for another key operator in Italy that I will name OPERATOR Y in this document, requiring a network solution to carry Data and ADSL traffic flows within a multi-vendor existing network. In the following chapters, I will describe some deeper aspects of the DWDM network design, as well as some SDH technical aspects accordingly to my tasks. </p><p>2. Scope of the work </p><p>2.1. Background After having already been working in it for around one year and a half, Huawei Technologies Co., Ltd. and being already familiar with the telecommunication industry within this solution provider, the position that I had in the optical networking department as product team member allowed me to get along with the latest optical transmission technologies, namely SDH and WDM networking. Dealing with several projects, my technical background needed to be reinforced by some further course in this field, and I found that the International Master in Communication Networks Engineering is able to meet my needs, either to acquire an overall technical background enhancement, or a comprehensive set o...</p></li></ul>
