Abstract

PURPOSE:To improve the reliability of a transmission line by setting an optional path among plural paths tying the transmission side and the reception side before the changeover at the transmission side and selecting a path tying the transmission side and the reception side at the changeover at the reception side. CONSTITUTION:A transmission side branch circuit 7 branches an input signal into two paths. A transmission line network where standby and active devices exist in mixture consists of a transmission side transmission line network changeover device 9, a reception side transmission line network changeover device 10 and relay station transmission station transmission line network changeover devices 11, 12. As to all the changeover patterns from the active to the active device, fro the active to the standby device, from the standby to the standby device and from the standby to the active device, the devices 9, 11, 12 are driven in advance to set the path tying the reception side and the transmission side is set and only the device 10 is operated at changeover so as to apply changeover. Thus, the reliability of the transmission line is improved.
