Embodiment 1
[0061] like Figure 5 As shown, the embodiment of the present invention provides a vectored DSL system, including: a DSLAM device; the DSLAM device includes at least two single boards, wherein at least one of the single boards includes an auxiliary vector processor, and the auxiliary vector processor is used for performing internal vectorization processing on the user data of the single board where it is located, and performing external vectorization processing on the user data of the single board containing the auxiliary processor by the centralized vector processor;
[0062] The centralized vector processor is used to perform external vectorization processing on the user data of the single board containing the auxiliary vector processor, and perform internal vectorization processing and external vectorization processing on the user data of the single board not containing the auxiliary vector processor.
[0063] The centralized vector processor is set in the DSLAM device, or ...
Embodiment 2
[0090] For the above-mentioned vectored DSL method, the embodiments of the present invention will further describe in detail. The method provided by the embodiment of the present invention is still based on Image 6 In the vector DSL system shown, the number of boards is N (N≥2), which are board 1, board 2, ..., board N; the number of users on each board is n (n ≥2), and the user of board 1 is X 1 ~X n , the user of board 2 is X n+1 ~X 2n , ..., the user of board N is X (N-1)n+1 ~X Nn ; and each single board contains an auxiliary vector processor. refer to Figure 9 , for the situation in which user uplink data is sent to the CO end, the method provided in this embodiment includes:
[0091] Step 901, the user sends its data to the board where the user is located;
[0092] i.e. user X 1 ~X n send its data to board 1, user X n+1 ~X 2n send its data to board 2, ..., user X (N-1)n+1 ~X Nn Send its data to board N. Specifically, it is sent to the early processing un...
Embodiment 3
[0111] In order to reduce the data transmission bandwidth between the single board and the centralized vector processor, the embodiment of the present invention Image 6 The illustrated scheme of the vectored DSL system is further optimized. Compared with the solution in the second implementation, the solution provided by the present invention further includes step S1 or step S2 before performing step 906, so as to know the users on each board that are strongly related to the lines of other boards, and only use these The user's data is sent to the centralized vector processor to achieve the purpose of reducing the bandwidth.
[0112] Step S1 and step S2 are two parallel solutions, and one of them can be selected.
[0113] Step S1, each board selects a user on the board that is strongly related to the subscriber lines of other boards.
[0114] In this step, the single board may select the user who is on the single board and is strongly related to the user lines of other singl...
