摘要： An apparatus and a system for hybrid-transmitting and bridging of a circuit service and a packet service are provided. The apparatus includes a TDM framing unit, a TDM three-direction cross unit, and a mapping and encapsulating unit. The TDM framing unit implements conversion between a line layer TDM signal outside the apparatus and channel layer TDM signals inside the apparatus, and transmits the channel layer TDM signals to the TDM three-direction cross unit. The TDM three-direction cross unit implements cross scheduling on the channel layer TDM signals from a TDM cross apparatus, the mapping and encapsulating unit, and the TDM framing unit. The mapping and encapsulating unit implements conversion between a channel layer TDM signal from the TDM three-direction cross unit and packet service signals from the packet processing unit.

摘要： A method and apparatus for splitting an asynchronous signal are provided. The method includes: buffering, according to frame sequence, an asynchronous signal to be split; and sending n frames of data respectively on n channels in parallel whenever n frames of data have been buffered, where n is a ratio of a rate level of the asynchronous signal before split to that of the asynchronous signal after split. A method and apparatus for signal combination are provided. The method includes: buffering n channels of parallel signals to be combined simultaneously according to frame sequence; and sending n channels of frames serially after one frame is buffered for each of the n channels of the parallel signals; wherein n is a ratio of a rate level of the parallel signals after combined to a rate level of the parallel signals before combined.
