PURPOSE:To provide the call incoming system, which calls a slave station from a master station without affecting any slave station excepting for the desired slave station to be basically called, concerning the call incoming control system used for calling the slave station from the master station at multi-connected 1-to-N communication systems. CONSTITUTION:A call incoming pattern having a prescribed frequency component is inserted into a signal frame transmitted from a master station 200 to respective slave station 100-1 to 100-n, and each slave station is equipped with a call incoming pattern detection part to detec the call incoming pattern from the received signal frame and to output a control signal, frame head detection part to detect the head position of the frame from the received signal frame and to output a signal showing the head position, frame position set part to set and output the frame position of its own station while inputting the output of the frame head detection part, and call incoming judgement part to judge whether the call is incoming to its own station or not while inputting the output of the frame position set part and the output of the call incoming pattern detection part. |
