Abstract

PURPOSE:To attain emergent calling from a general terminal equipment, by allowing a master station to discriminate the correctness of an emergent calling request by emergent calling distiination connection information from a slave station received from an information transmission channel and connecting a subscriber line corresponding to the terminal equipment making a true emergent calling request to the emergent calling channel. CONSTITUTION:A main control section 14 discriminates the correctness as to whether or not the emergent calling destination connection information sent from a slave station 4-1 is a calling request to a predetermined calling request. When it is discriminated that the request is the true calling request, the main control section 14 outputs the dial signal being the emergent destination connection information to an emergent calling destination connection information transmission section 15 and a transmission section 15 sends the dial signal to the exchange 1. The exchange 1, based on the dial signal, applies the communication line connection between the terminal equipment 6-1 making emergent calling request and the terminal equipment of the emergent calling destination. Thus, even if all communication channels on the transmission line between the master station 3 and the slave station 4-1 are busy, the emergent calling is applied from a general subscriber terminal equipment 6-1.
