PURPOSE:To make each operation independent without being influenced by the travel of a mobile object with a call control part or without being influenced by a call control with a travel control part by controlling and using another transmission line mutually by the call control part and the travel control part and connecting both parts with a physical transmission line. CONSTITUTION:A call control part 10 controls the call of an exchanger. A travel control part 20 controls the switching of a transmission line by the travel of a mobile object 30. A transmission line 1 is the transmission line controlled by the call control part 10 and connected with a fixed connecting point P1. Transmission lines 2, 4 and 5 are the transmission lines controlled by the travel control part 20, switched by the travel of the mobile object 30 and always connected with a fixed connecting point P2. The section between two fixed connecting points P1 and P2 is connected by a physical transmission line 3. |
