PCT No. PCT/DE88/00273 Sec. 371 Date Sep. 12, 1989 Sec. 102(e) Date Sep. 12, 1989 PCT Filed May 5, 1988 PCT Pub. No. WO88/09997 PCT Pub. Date Dec. 15, 1988.Circuit arrangements (ULB) can be connected to one another with the assistance of a connection network (VN). Every circuit arrangement (ULB) can thereby operate as transmitter or as receiver. The connection network (VN) contains a matrix that is composed of a connection matrix and of an adjustment matrix. In the connection matrix, the data lines (DL) leading to the circuit arrangements (ULB) cross with coupling lines, whereby switching elements are arranged at the crossing locations. The adjustment matrix is composed of adjustment lines that cross with the coupling lines, whereby switching elements are arranged at the crossing locations. The connections between the data lines can be determined by programming the switching elements in the connection matrix and in the adjustment matrix and by applying an adjustment code to the adjustment matrix. The assistance of control signals can thereby be used to determine whether the data lines represent a data input or a data output.
