MULTIPLE ADDRESS BROADCAST EQUIPMENT

PURPOSE:To implement multiple address broadcast by allowing a digital communication network to continuously connect a broadcast equipment corresponding to a telephone number read from a memory card and sending a voice signal from a broadcast source. CONSTITUTION:A data read section 2 reads the telephone number of a broadcast equipment from a memory card 1. The signal is identified by an identification section 3 and the equipment is connected to a relevant broadcast equipment by a digital communication network through a line control section 4. The connected broadcast equipment identifies the telephone number by the input signal and connects to a relevant succeeding broadcast equipment by the digital communication network. Succeedingly a voice data is read from the memory card 1 by the required operation and the data is sent to the digital communication network via the line control section 4 and delivered to each connected broadcast equipment. Each broadcast equipment uses a D/A conversion section 8 to convert the inputted voice data into an analog signal, which is sounded out via a voice output section 9. In the case of broadcasting a voice of a microphone, the microphone is selected and the voice of the microphone is received via a voice input section 6 and an A/D converter section 7 converts the voice into a digital signal, which is sent.
