Abstract: A carrier configuration method and system for a distributed antenna system, a processing device, and a chip are provided. The distributed antenna system includes at least one access unit and at least one remote unit. The method includes: acquiring a configuration parameter of a carrier to be transmitted of at least one access unit, the configuration parameter including a mapping relationship between the at least one access unit and the at least one remote unit; and establishing a transmission channel between the at least one access unit and the at least one remote unit according to the mapping relationship.

Abstract: An active-standby switching processing method and system, and an electronic apparatus and a storage medium are provided. The processing method is applied to an active system and a standby system. The active system is connected to the standby system by means of an external warning line. The processing method includes: acquiring a device detection result of the active system; and according to the device detection result, instructing the active system to send a detection signal to the external warning line, and according to the detection signal, executing a switching operation between the active system and the standby system.
