摘要

PURPOSE:To omit wiring even when the relocation of desks, the change of an object person to be displayed and the like occur and to easily cope with that by adding an information transmission/reception function to a part of a private pocket bell system. CONSTITUTION:This system uses a telephone set 4 disposed in an office and the like and consists of an input switch part utilizing the pacing trunk for the private pocket bell of an private exchange 7 and a presence and absence state display part 5 having a reception circuit for the private pocket bell (a radio reception device). Then it adopts a system using a radio instead of a conventional leased cable wiring system. Thus the work such as the rewiring of the leased cable wiring becomes unnecessary when the office and the like is rearranged.
