Abstract

PURPOSE:To simply connect a telephone line between an exchange and a track moving body by transmitting/receiving information between plural exchanges and setting up a channel between the exchanges while tracing the track moving body. CONSTITUTION:Trace processing is executed by one group of four trunks consisting of a speaking line #0 for a tracing call and channel specifying lines #1-3 for informing a radio channel generating tracing. One line corresponds to a channel reservation instructing line xsi4 and the lines #0-4 is based upon a 4-line type SS/SR system. An exchange 2 in a station A detects the generation of movement to an exchange 3 in a station B, graps a moving channel number b the states of SR lines of the lines #1-3 and switches the connection of a speaking path from a radio channel (i) to the line #0. Then, the SS line of the line #0 is turned on, the completion of connection switching is informed to the exchange 3 and the exchange 3 sets up a speaking path between the line #0 and the radio channel (i).
