ABSTRACT:
A control circuit (1) determines transmission power for a test signal in accordance with the number of call connections of a radio terminal call-connected to the apparatus during a loopback test. The determined transmission power (TSTP) is output to channel circuits (21-2n) used for the transmission of a loopback test signal. The channel circuits (21-2n) adjust the transmission power of the test signal on the basis of the transmission power (TSTP) from the control circuit (1).
