Abstract

PURPOSE:To obtain the representing selection system which can distribute the incoming call equally to the extensions belonging to the same extension representing selection group and can make incoming call suitably even during calls. CONSTITUTION:When an incoming call is present, the incoming side location identifying circuit 1 transfers the extension allocation information in the extension location information storage register 21 inside the circuit 1 to the extension location information storage register 22 in the representing selection memory readout circuit 3. The extension status identifying circuit 14 checks the vacancy/busy of the corresponding extension with the extension location information stored in the extension location information storage register 28, and when the extension is busy as the result of check, the transferred information at entire busy call is stored in the entire busy call transferred information storage register 17 via the memory address control circuit 54 with the representing selection group information present in the representing selection group information storage register 75 in the entire call busy transferred memory 15.
