Abstract

PURPOSE:To realize digital data switching among stations, by performing commu nication between an outgoing station and an incoming station by a common line signal system, and providing an opposite station call signal and a call confirmation signal for data switching, and furthermore, means for signal editing, signal delivery reception, state confirmation, terminal identification, and signal identification. CONSTITUTION:In the outgoing station and the incoming station, signal editing means 41 and 111 to edit a data switching signal, signal delivery reception means 42 and 112 to receive the data switching signal via common line signal devices 6 and 13, state confirmation means 43 and 113 to perform the state confirmation of data terminals 1 and 8 of an opposite station, terminal identifica tion means 44 and 114 to perform the transmission/reception of the attribute information of the data terminals 1 and 8 and to discriminate the data terminal of different kind, and signal identification means 45 and 115 to discriminate whether or not received data is the one modulated by a voice or a modem or the one as it is are provided, and the transmission/reception can be performed between the common line signal devices 6 and 13. In such a way, it is possible to perform the digital data switching between both stations.
