<p><P>PROBLEM TO BE SOLVED: To provide a repeater station which monitors occurrence of a fault by sending monitor information to a monitor information processing apparatus on a play site, and also to provide a multi-stage relay system using said repeater station. <P>SOLUTION: The present invention relates to a repeater station and multi-stage relay system using the same for relaying a terrestrial wave digital television broadcast wave and comprises: an MER detector 72 for detecting an MER value at an output side of a reception section 10 comprising a repeater station 100; a reception power detector 71 for detecting reception power; a bias current detector 73 for detecting a bias current of a transmission power amplifier 51; and a transmission power detector 74 for detecting transmission power. The MER detection value or the like is sent to a monitor information processing apparatus 198 as repeater station monitor information, and a fault cause block and a fault repeater station are specified therein based on the repeater station monitor information. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
