VOICE COMMUNICATION SYSTEM FOR INFINITE COMMUNICATION NETWORK

摘要

PURPOSE:To attain communication with an optional network without using a selection signal by broadcasting a data from a node equipment detecting call according to the logic of the order of arrivals to other voice communication equipments not busy. CONSTITUTION:When a voice communication equipment 1 hooks off a handset, a reception section of a node equipment 20 receives a data signal and a carrier signal sent from a modulator 22 through a signal line. In receiving a carrier, the node equipment 20 sends a carrier to other node equipments 20 and a voice communication equipment to be connected. When a caller utters 'Mr. A' toward the transmitter 24, the voice is broadcast all to all idle voice communication equipments according to the logic of the order of arrivals. When Mr. A responds to the call by a voice communication equipment 2, a carrier being a response signal is sent to the node equipment 20, the communication equipments 1 and 2 are connected to be in the calling state.
