PURPOSE:To separate a failed transmission line by arranging properly a transmission line separating device in a bus transmission line. CONSTITUTION:The transmission line separating device 11 is provided at a proper position of the bus transmission line between the transmission lines 12a and 12b. If a failure such as open line occurs in the transmission line 12a at an end, a switch S1 is operated, contacts (a), (b) are closed so as to disconnect the transmission line 12a and terminate the line by a terminating resistor R0 at the same time. |
