Abstract:
1. A method for multi-path TDM data transmission comprising: applying a plurality of high-speed serial lines to connect a center switch network board with a plurality of service boards respectively, wherein the center switch network board provides a sync signal and a clock signal to, and exchanges TDM data with, each of the plurality of service boards via a respective one of the high-speed serial lines; obtaining, by the center switch network board, multi-path TDM data according to the sync signal and the clock signal, multiplexing, by the center switch network board, the multi-path TDM data and transmitting the TDM data multiplexed in batch to the plurality of service boards via the plurality of high-speed serial lines; receiving, by the plurality of service boards, the TDM data multiplexed, and de-multiplexing the TDM data multiplexed to the multi-path TDM data according to the sync signal and the clock signal; wherein said obtaining multi-path TDM data according to the sync signal and the clock signal, multiplexing the multi-path TDM data and transmitting the TDM data multiplexed in batch to the plurality of service boards via the plurality of high-speed serial lines comprises:
