ABSTRACT:
A system for replacing obsolete postal rate data with new data used by a remote mail processing apparatus comprises a central data processor for generating the new data. An encoder translates the new data into electronic tone signals which are transmitted to the remote apparatus by, for example, telephone transmission lines. The electronic tone signals are translated back into new data by a decoder. A memory incorporated in the remote apparatus is equipped to store obsolete or new data at a plurality of storage locations and a programming transfer controller, which interconnects the decoder and memory, sequentially addresses each of the locations storing obsolete data, erases the obsolete data, and loads new data into the addressed location.
