摘要： An electronic digital signal cross-connect system (EDSX) is provided which includes a plurality of input terminals for respectively receiving bipolar 3-level input signals having a predetermined bit rate, and a plurality of output terminals for respectively providing bipolar 3-level output signals having the same predetermined bit rate. An interface circuit is provided which has an input section coupled to the input terminals to receive the bipolar 3-level input signals and an output section coupled to the output terminals to output the bipolar 3-level output signals. The input section of the interface circuit is constructed to include converting circuitry for converting the bipolar 3-level input signals into predetermined coded signals. Correspondingly, the output section of the interface circuit includes converting circuitry for decoding the predetermined coded signals into bipolar 3-level output signals. A switching matrix having a plurality of switching units is arranged between the input section and output section of the interface circuit. A control unit is coupled to the switching matrix to control the switching units in a manner to couple predetermined ones of the inputs of the switching matrix to predetermined ones of the outputs of the switching matrix. By virtue of this control of the switching units of the switching matrix, the cross-connection between input terminals receiving bipolar 3-level input signals and output terminals providing bipolar 3-level output signals is controlled. Further, by virtue of the coding arrangement used in the present invention, the EDSX is transparent to any bipolar violations which may exist in the bipolar 3-level input signals.
