PURPOSE:To enable to process the call from a number of markers, by dividing the functions of the number group of the cross-bar exchanger into the electronic circuit performing representatie selection and the electronic circuit processing common calls. CONSTITUTION:To the memory unit MEM at one electronic circuit A connected to the marker M, the identification information whether it is the allocation information of exchaner and the representative poiot or not corresponding to the subscriber number, is memorized. Further, if it is the representative pilot, the subscriber number information is delivered from the circuit A to the other electronic circuit B, the circuit B reads out the representative line group number corresponding to the subscriber number, the C line of the exchanger line link is fetched with the representativel selection circuit, the vacant line is selected, the allocation information memorized corresponding to the representative line from the vacant line number is read out, and the information is delivered to the marker M through the circuit A. Accordingly, a number of calls for the marker can be processed with the circuit A performing representative selection for the functions of the number group and the circuit B processing common calls. |
