PURPOSE:To attain the miniaturization of equipment, the reduction in operating time and the reduction of noise at operation, by processing each connection such as receiving processing in order of incoming, holding processing, hold receiving processing in order of holding and processing of line designating reception in response to input information from each operating board. CONSTITUTION:When a receiving access key K is operated by the operator of a certain attendant board BDi, the information accesses a data memory section S4 via an access key input section S3, a line data of a line incoming fastest among lines not yet connected but incoming at present is read out from a data memory section S4, a switch connection control section S1 is started, resulting that a connecting switch SW including a control circuit is controlled to connect a trunk TRK of the line and the operating circuit POS of the attendant board BDi. Thus, the operator of each attendant board receives the incoming from the fastest in order among the incoming lines not yet connected at present, by operating the access key K received with the own board. |
