This Technical Report concerns the following communications deliverable within M/441:
A European standard comprising a software and hardware open architecture for utility meters that supports secure bidirectional communication upstream and downstream through standardized interfaces and data exchange formats and allows advanced information and management and control systems for consumers and service suppliers.
The architecture must be scalable to support from the simplest to the most complex applications.
Furthermore, the architecture must consider current relevant communications media and be adaptable for future communication media.
The communication standard of the open architecture must allow the secure interfacing for data exchanges with the protected metrological block.
