Abstract
The invention relates to a three-stage switching arrangement for electrical message switching technology. In a known three-stage and non-blocking switching arrangement, the switching matrices, of which the individual stages are constructed, have different numbers of inputs and outputs. Thus three different models of switching matrices are required. The invention is based on the object of specifying a switching arrangement of the above- mentioned type in which the switching matrices of all stages are of the same structure. The object is achieved by the fact that, among other things, the switching matrices (G1...G16) are distributed to two switching networks (KF1, KF2), that the number of inputs (16) of a switching matrix is equal to the number of its outputs (16) and that the inputs and outputs (E001...E256, A001...A256) of the first switching network (KF1) are connected to the identically-named inputs and outputs, respectively, of the second switching network (KF2). The invention also deals with developments for being able to use the switching arrangement for transmitting digital signals having a bit rate of up to 150 Mbit/s. <IMAGE>
