The present document provides: ? a detailed description of Use Cases demonstrated during the C2C-CC Forum and Demonstration event 2008; ? a report on the corresponding technical specifications of the demonstrator system covering all communication layers. It is understood that the C2C-CC demonstrator 2008 did not implement the complete functionality of a final system. However the implementations have been specified with a high demand with respect to interoperability and the current standardization status Therefore@ it is intended that this report contributes to future standardization work: ? with a basic description of selected use cases; ? with a definition of a basic set of Application Support Facilities (CAM/DNM)@ which enable the selected use cases; ? with the specification of basic settings of the underlying communication layers (PHY-TRA) including communication security. Moreover@ the present document gives an example on how to visualize basic technological mechanisms such as Application Support Facilities (ASF)@ which are usually hidden to an end-user. This is can be of great value for future public demonstrations and interoperability tests.
