CATVシステム用通信装置。[Claim for Utility Model Registration] A center device and multiple terminal devices are connected using the transmission path of the CATV system, and the center device sends out a paging signal using modulated waves to call the terminal device and respond to the paging signal. In a communication device for a CATV system that sends a response signal in the form of a modulated wave from a terminal device to a center device, the center device is provided with means for prohibiting the reception of a response signal from the terminal for a predetermined period of time after the terminal device sends a calling signal. and means for starting returning a terminal response signal to each of the terminal devices within the predetermined time, and transmitting a valid data response signal after the predetermined time has elapsed.
Communication equipment for CATV systems.
