Preface This projects concerns the creation of an automatic planning method in FTTH access network with and without redundancy. The report is prepared at the Faculty of Engineering and Science at Aalborg University Net- work Planning and Management, in the period from the 4th of September 2006 to the 7th of June 2007. The overall theme for the semester is Network Planning. The project group have hereby selected the project proposal Of automatic planning access network with and without redundancy, Instructions for reading Some practical guidelines about how to read this report. • Citations will be referred to with square brackets e.g. test-citation[3]. The number in the square brackets can be looked up in the back of this report under ’Bibliography’. • Footnotes will be used to deepen sentences e.g. This needs a additional comment1. • Abbreviations will be fully written the first time they are used e.g. Please Shorten This (PST). • All source materials will be available on the enclosed disk found on the rear page of the report. Report Structure The report is structured like stated below. It is divided into four parts which follow a step by step approach. Part I: Background: The first part contains the introduction to network planning and then the area of the case study. It will then list and describe the scenarios used in this project. At the end of the part it will furthermore define the project goal. Part II: Phase 1: This part will introduce phase 1, which main goal is to reduce fiber in small scale tests. Also introduction s given to the automation process. Next results are given to scenarios created and compared. Finally a conclusion is given to the results, and criteria’s set for phase two. Part III: Phase 2: This part will introduce phase 2, which will finish of larger parts of the automatic process. Scenarios are created based on criteria’s given in phase 1. Results are given and compared. Finally a conclusion is given to this phase. 1The footnotes will try to deepen the sentence 1 Part IV: Recapitulation: The forth part will make a conclusion to the automatic plan- ning process creation and the results of both phases. Part V: Appendix: The last part contains the appendix with supporting/elaborating in- formation to different parts of the report. The enclosed CD contains the program code, a copy of the report in portable document format (PDF) and all calculation sheets.
