d functionality, and obtain the necessary configuration. This work requires some kind of fairly detailed rules. System integration is a key process to get everything to work properly. As mentioned, business views are also important, and over-provisioning may not be an option for economical reasons. Further, all involved parties have a common interest in transforming the network smoothly. Control functions, traffic functions and resources, as well as management functions are concerned. 3.6.2 TOOL The tool, which is used in this book in order to manage successfully the challenging transition, is thus the fundamental technical plan or FP. As seen from Figure 3.20 the FPs are an input to network planning. The boxes with broken/dashed lines are an adaptation in this book to multi-service and multi-media. The basic figure comes from ITU-BDT/Planitu. Planitu is a network planning tool provided by ITU for optimization and dimensioning of telecommunications networks. The meaning of the term telecom management in the figure is broader than the abbreviated TM used in this book (which is service + network management). The use of this overview (Figure 3.20) is intended to contribute to a better overall understanding. The FP is thus used to make an overall end-to-end requirement specification for the network and then, as a second step, to distribute the requirements and functional capabil- ities to the various network parts and platforms. The chosen IETF, ITU and 3GPP (and other) standards should be indicated in the FP specifications. The language in an FP is normally supplier independent. Let us call it 'operator lan- guage'. FPs must be updated and adapted to changing conditions.
