Abstract

PURPOSE:To obtain the unit suitable for medium and small sized digital exchange system, by avoiding physical restriction through the simplicity of coupling of constituent units and by LSI through the incorporation of the time sharing switch module into line correspondence module. CONSTITUTION:The time sharing exchange system communication path system consists of 6 sets of communication path modules M0-M5 incorporating the line correspondence section provided according to the subscriber line LC or office line and the time sharing switch section forming the communication path of communication message. The time sharing switch section of the modules M0-M5 consists of the time sharing multiplex circuit MUX and the time sharing communication path memory PM including the time sharing multiplex separation circuit DMUX, and the modules M0-M5 are connected with the two systems of buses via the bus interface element. Further, the line correspondence section is provided with the subscriber circuit LC, subscriber line concentrator C, and coding and decoding circuit CODEC and further, with the interface DT1 between digital stations, push button multi frequency receiver PBREC, and multi-frequency receiver between stations MFREC.
