Abstract

PURPOSE:To eliminate necessity for always turning on the power source of an auxiliary device, to improve running cost and to prolong the service life of the device by performing switching to the auxiliary device and the turning-on of the power source of the auxiliary device at a present device as well when a command received at the switching device is a switching command. CONSTITUTION:A switching device 10 is composed of host line switchers (SWH) 11-1-11-m for switching the host lines of devices 20-1-20-m to a device 20-n, remote line switchers (SWR) 12-1-12-m for the devices 20-1-20-m, and control system 13 for controlling the switching device 10. A switching command judging part 131 of the control system 13 judges whether the command received at the switching device 10 is the switching command or not and when the judged command is the switching command, a power source ON switching part 132 turns on the power source of the auxiliary device 20-n. Then, a switching part 133 switches the input/output line connected to the device 20-1 to which switching is commanded, for example, to the auxiliary device 20-n.
