A full-T cross apparatus and method are provided. The full-T cross apparatus includes an input module, which includes multiple input channels; and multiple output modules, each of which includes an output channel, an output control module, and multiple data storage modules. Each of the multiple data storage modules is corresponding to each of the multiple input channels of the input module. The multiple output modules are configured to receive service data from the multiple input channels according to the output channels corresponding to the service data, and send the service data according to output time slots corresponding to the service data. In this way, the chip size is reduced to some extent, and further, the costs and power consumption of the chip are reduced.
