ABSTRACT:
In a method and apparatus for dependable transmission of data from a data center to terminal equipment, particularly transmission of fee schedule table data to a postage-calculating scale or postage meter machine, new postage fee schedule table data are offered at the data center for future postage calculation. In a first communication between the data center and the terminal equipment, a request for postage fee schedule table data is formed at the terminal equipment and is communicated to the data center, and the data center receives the request and transmits the requested new service data to the terminal equipment, and the terminal equipment receives and stores the new service data. Thereafter a second communication takes place between the data center and the terminal equipment, wherein the terminal equipment forms a message referring to the stored, new service data and this message is communicated to the data center, where it is checked against information generated at the data center from the new service data. Given a positive comparison result the data center transmits a message to the terminal equipment allowing usage of the validated new service data.
