Vectored-DSL method and system, board, and DSLAM device

摘要

A vectored-DSL method and system and a board relate to the field of digital subscriber line DSL data processing, so as to increase user capacity of a vectored-DSL system. The vectored-DSL method includes: receiving, by at least one board, and pre-processing user data of the board; transmitting, by the board, the user data of the board to an auxiliary vector processor on the board to perform internal vectorization processing, so as to obtain internally processed data; transmitting, by the board, the user data thereof to a centralized vector processor to perform external vectorization processing, so as to obtain externally processed data; and receiving, by the board, the externally processed data of the board, and post-processing the externally processed data and the internally processed data.

1. A vectored-DSL method, comprising:
receiving, by at least one board, and pre-processing user data of the board; transmitting, by the board, the user data of the board to an auxiliary vector processor on the board to perform internal vectorization processing, so as to obtain internally processed data, wherein the performing of internal vectorization processing comprises: when the user data is transmitted by a user to a central office, CO, of a vectored-DSL system, performing crosstalk elimination by the auxiliary vector processor to eliminate crosstalk incurred between users on the board; transmitting, by the board, the user data of the board to a centralized vector processor to perform external vectorization processing, so as to obtain externally processed data, wherein the performing of external vectorization processing comprises: when the user data is transmitted by a user to the CO, performing crosstalk elimination by the centralized vector processor to eliminate crosstalk incurred between a user of each board and users of other boards; and receiving, by the board, the externally processed data of the board, and post-processing the externally processed data and the internally processed data.
