Abstract: The present disclosure provides a method for accessing a cloud service and an access device. The method includes: sending, to a to-be-accessed cloud service, an access request packet that includes a cloud service interface type identifier of a piece of characteristic information and an access address of the to-be-accessed cloud service, when an access response packet that is returned by the to-be-accessed cloud service and that indicates successful matching is received, using interface version information corresponding to the cloud service interface type identifier as target cloud service interface version information, and connecting to the to-be-accessed cloud service based on the target cloud service interface version information and the access account. In this case, a degree of complexity of establishing a connection to a cloud service is decreased, and work efficiency is increased.

Abstract: An echo cancellation method and a transceiver to reduce dependence of a system on an enob of a DAC, and improve performance of echo cancellation. The transceiver includes an echo cancellation apparatus, a transmit link, a receive link, and a hybrid circuit. The transmit link and the receive link are coupled to a transmission line by using the hybrid circuit. The echo cancellation apparatus includes a first signal converter, a slicer, a first subtractor, a second digital-to-analog converter, a second subtractor, and a third subtractor.
