摘要： In a BRE300, an RF interface for transmitting and receiving an RF signal is used for communication with a MDE 200 and a digital signal interface for transmitting and receiving a digital signal in accordance with CPRI is used for communication with BDE 300. The BRE 300 includes a monitoring signal interface configured to notify the MDE 200 of a monitoring signal indicating a state of the radio unit 50. The signal transmitted and received through the monitoring signal interface is a ground signal and is of type different from types of signals transmitted and received by the RF interface and the digital signal interface.
