Abstract

PURPOSE:To attain emergent communication from a general terminal equipment, by providing an emergent channel to a transmission line between a master station and a slave station, allowing the slave station to use emergent communication destination connection information receive from a terminal equipment so as to discriminate the correctness of the emergent communication request, giving assignment request of the emergent calling channel to the master station and allowing the master station to apply the assignment control based on the request. CONSTITUTION:A dial signal being emergent communication destination connection information from a subscriber is given to a slave station control section 19 via a call information detection section 16-4. The slave station control section 19 collates the dial signal with an emergent communication destination list processed in its own station to discriminate the correctness of the emergent calling request. As to the true emergent calling request, the emergent calling channel assignment request information is sent to the master station 3 via an information transmission channel. A main control section 14 receiving the emergent calling channel assignment request information applies assignment control to one channel among emergent calling channels to a 1st multiplexing/demultiplexing means 13. Thus, communication from one general subscriber terminal equipment to a specific emergent communication destination is attained.
