ABSTRACT:
This invention relates to an information network such as a telepoint network, having discrete communications units, such as telephone communications handsets (14), where each unit has a user-inaccessible memory. The invention also applies to networks of other units, such as smart cards. The network has regional controllers (11 and 12) for funnelling information from base stations (10) into a central controller (13). At the central controller, analysis of past communications is carried out and, based upon this, instructions are sent out to selected regional controllers for programming the memories of selected regional controllers for programming the memories of selected discrete units when those discrete units next communicate with base stations associated with the selected regional controllers.
