Abstract: A data transmission method includes an optical line terminal (OLT) for obtaining a data template. The OLT then obtains corresponding optical network terminal (ONT) data based on one or more data types defined in the data template. The OLT then encodes the ONT data according to an external data representation (XDR) format and sends encoded ONT data to a management server. Further, the management server stores and manages the ONT data. The OLT collects the corresponding ONT data based on the data template, encodes and reports the ONT data according to the uniform XDR format. The embodiments define a unified statistics collecting and reporting manner of ONT data and uses standardly defined ONT data to help the management server store and manage the ONT data.

Abstract: An analog-to-digital converter protection circuit, a method for controlling an analog-to-digital converter protection circuit, and a controller are disclosed. The analog-to-digital converter protection circuit includes: an analog switch, an analog-to-digital converter, a controller, and a series circuit including at least two resistors connected in series. The controller is configured to: when the digital voltage is greater than or equal to a preset voltage threshold, output a control signal to the analog switch, to trigger the analog switch to control to a second sampling end from a first sampling end to serve as the conduction sampling end to conduct to the output end of the analog switch, where an analog voltage sampled by the second sampling end is less than an analog voltage sampled by the first sampling end; and when the digital voltage is less than the preset voltage threshold, output the digital voltage.
