Abstract

A data transmission device, system and method are provided by the present invention. Wherein, the data transmission device includes: the first exchange unit is used for extracting N slots data within 2N slots exchange data from the other data transmission device and transmitting it as the second downstream exchange data; the downstream processing unit is used for receiving the second downstream exchange data transmitted by the first exchange unit, extracting N slots data within 2N slots downstream data from the optical port to be the first downstream data, combining the first downstream data with the second downstream exchange data and then transmitting it to the service board; wherein, N is the integer. Through the invention, cross particle can be reduced and cross capacity can be expanded.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission device, system and method. Background technique [0002] At present, in the communication transmission system, the TFI5 bus is a relatively common backplane connection bus at present, and is used to connect various service boards and cross-connect boards. When the Synchronous Digital Hierarchy (SDH for short) or Optical Transport Network (OTN for short) service on the optical port side is mapped to the TFI5 bus, the number of mapped channels depends on the rate of the optical port service and the rate of the TFI5 bus. , the crossover capacity and the scale of the devices used are considered comprehensively. [0003] However, in the related art, it is impossible to provide smaller intersecting particles, so that a larger intersecting capacity cannot be provided. Contents of the invention [0004] The present invention is made in consideration of the probl...
