Swisscom Fixnet Ltd. has evaluated a new platform for the broadband transport requirements. This new platform will be a combination of advanced SDH (Synchronous Digital Hierarchy) and WDM (Wavelength Division Multiplexing) technology and the principal goal is to cover the bandwidth segment between STM-1 and STM-64. In addition new forthcoming data services e.g. Gigabit Ethernet can be delivered on the same platform infrastructure between remote areas. This paper describes the drivers for the project as well as the requirements at the start of the evaluation process of the transport platform. The requirements include technical, operational and financial aspects. The main focus will then be the discussion of the core, metro or regional area architecture. Various scenarios have been analyzed and compared. The main conclusions have been that the number of "flexibility points" should be kept lower than in traditional SDH-network due to cost reasons in a broadband environment with packet oriented services. Furthermore, the WDM technology is not economically reasonable for a low number of channels in the regional area. The paper then summarizes these lessons learned from the project.
