    Abstract: An optical transmission device is disclosed, comprising a tributary board, an active line board, a protection line board, an optical amplifier board, an electric cross unit, and a first multiplexer/demultiplexer board. The first three boards are electrically connected to the electric cross unit. The second to fourth boards are optically connected to the first multiplexer/demultiplexer board. A quantity of protection line boards is less than that of active line boards. A first port of the tributary board and a second port of the optical amplifier board are respectively configured to transmit client service data and an optical signal carrying the client service data. When a preset condition is met, the electric cross unit copies or schedules, to the protection line board, client service data to be processed by the active line board, and the first multiplexer/demultiplexer board performs multiplexing and demultiplexing together with the protection line board.

    Abstract: Various embodiment provide a multi-terminal cooperative working method, a terminal device, and a multi-terminal cooperative system. In those embodiments, a primary device can send networking information to a plurality of secondary devices, and the primary device has a permission to manage the cooperative network. The primary device can receive networking confirmation information sent by the plurality of secondary devices; and send configuration information to the plurality of secondary devices separately. The configuration information can be used to instruct to switch, based on a preset management permission switching mechanism when the primary device becomes abnormal or the primary device exits from the cooperative network, the permission to manage the cooperative network. The primary device can clear the secondary device from the cooperative network the secondary device becomes abnormal. In this way, robustness of the cooperative network can be improved.

    Abstract: Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted, thereby improving a noise cancellation effect and user experience.
