Signal) 12 received by the base station signal processing unit 8,
The other processing unit 10 of the base station performs initialization according to the procedure determined for each.

After turning off the electrical physical state of the line 13 connected to the base station apparatus 1, the control station apparatus 4 issues an instruction to turn on the electrical physical state of the corresponding line 13 of the base station apparatus 1. By performing this to the layer 1 (ON / OFF) control unit 6, the layer 1 control signal 11 (ON) for turning on the electrical physical state of the corresponding line 13 is sent to the layer 1 operation unit 7, The electrical physical state of the corresponding line 13 is turned on.
