FDT2.0 will improve interoperability and will optimize DTM resources utilization. FDT2.0 will speed up calling times and data storage times of DTMs. With FDT2.0 you will use a future-proof technology. Backwards compatibility is one of the highest priorities of FDT2.0 thereby ensuring that existing 1.2.x DTMs can still be used in an FDT 2.0 application.
