Abstract

PURPOSE:To attain emergent communication from a general terminal equipment, by allowing a master station to discriminate the correctness of an emergent talking request by emergent calling destination connection information from a slave station received via an emergent calling channel and to connect a subscriber line corresponding to a terminal equipment making the true emergent calling request to the emergent calling channel. CONSTITUTION:In receiving the emergent calling destination connection information sent from the slave station, a main control section 14 of a master station 3 discriminates the correctness as to whether or not the emergent calling destination connection information is a calling request to the emergent calling destination predetermined in advance. In case of the true emergent calling request as the result of discrimination of the correctness, the main control section 14 controls the emergent calling channel and the subscriber interface section 11-1 making emergent calling request so as to be connected together to the line concentration multiplexing/demultiplexing section 13 of a 1st multiplexing/demultiplexing means 13. The main control section 14 outputs the dial signal being the emergent calling destination connection information to the information sending section 15. The transmission section 15 sends the dial signal to an exchange 1 via the subscriber interface section 11-1.
