<P>PROBLEM TO BE SOLVED: To enable a wireless base station to restart a wireless transmission and reception section in the case that communication of a control signal between the wireless base station and the wireless transmission and reception section is disabled due to a fault in a control circuit of the wireless transmission and reception section. <P>SOLUTION: When the wireless base station 11 confirms that no health check response comes from the wireless transmission and reception section 20, the wireless base station 11 discriminates that a fault takes place in the wireless transmission and reception section 20 and uses an electrooptic conversion section 16 to control an output of an optical line 17. A reset control section 22 of the wireless transmission and reception section 20 monitors an input state of the optical line 17 and resets each circuit of the wireless transmission and reception section 20 when the wireless transmission and reception section 20 confirms that the wireless base station 11 controls the output of the optical line 17. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
