ABSTRACT:
In a transmission network have a tree structure in which data is forwarded from the tree branches toward the trunk at periodic intervals, the data which is transmitted between the several network levels is reduced by deleting data corresponding to a predetermined information content corresponding to the most probable configuration of such data. The remaining data is divided into sub-sets and transmitted with an individual sub-address for each sub-set, and a control signal identifying the number of sub-sets which are transmitted, and an address identifying the sending station. Optionally, when more than half of the sub-sets contain information not corresponding to the predetermined information, the data blocks are transmitted without sub-addresses but with a control block which identifies a mode in which all sub-sets are transmitted without sub-addresses.
