Abstract: PURPOSE: A duplicating unit of a transceiver shelf of a communication system using a current monitoring is provided to early overcome call quality and capacity degradation of a reverse link and an instantaneous cell radius reduction phenomenon of a forward link caused due to an abnormal DCC and UCC by constantly monitoring an amplifier of the DCC and UCC of a transceiver shelf by monitoring current. CONSTITUTION: The first and second switching units(11,12) respectively output alpha, beta and gamma sector signals to a DCC and a UCC sector according to a switching control signal of an RFC. The third and fourth switching units(13,14) output alpha, beta and gamma sector signals outputted from the DCC and the UCC by each sector according to a switching control signal of the RFC. An RFC(15) controls a down-converting and up-converting operation of the DCC and the UCC by each alpha, beta and gamma sector, and outputs a switching control signal for switching an abnormal path of the DCC or the UCC to a redundancy DCC or UCC if there is an error in the DCC or the UCC by each alpha, beta and gamma sector. Alpha, beta and gamma sector DCCs(21-23) respectively down-convert alpha, beta and gamma sector signals and output it to the third switching unit(13), and perform a current monitoring for an amplifier. A redundancy DCC(24) receives signals by each sector inputted to an abnormal DCC and down-converts it if there is an error in the amplifier when the current is monitored for the amplifier. Alpha, beta and gamma sector UCCs(31-33) up-convert alpha, beta and gamma sector signals inputted through the second switching unit(12), outputs them to the fourth switching unit(14), and performs a current monitoring for the amplifier of the alpha, beta and gamma sector DCCs(21-23). A redundancy UCC(34) receives signals by each sector inputted to an abnormal UCC through the second switching unit(1) and up-converts it if there is an error in the amplifier when the current is monitored for the amplifier of the alpha, beta and gamma sector UCCs(31-33).
