ABSTRACT:
The invention relates to a transfer arrangement comprising a plurality of stations that are connected to each other via separate write lines and read lines, the write line at one position being coupled to the read line. The information transfer from one station to another is effected through a data channel that is formed by an allocated time slot in periodic frames. In order to realize an improved use of the data channel in the case of mutually simultaneous information exchange between two stations, according to the invention only one data channel is occupied through which each station reversibly links the information arriving through the incoming write line to the information to be transferred, preferably by means of an exclusive OR gate, and in addition, each station links the received information again to the transferred information, thus recovering the information transferred by the other station.
