[0024] This embodiment provides a method for a vectoring system to identify an external serial port, which can be performed by a network management device. figure 2 is the flowchart of the method, such as figure 2 As shown, the method includes the following processing:
[0025] Step 201: Determine the first port that is currently in the link building state in the vector group of DISLAM;
[0026] Optionally, in this embodiment, before performing the above step 201, the following processing may also be performed:
[0027] Before determining the first port in the DISLAM vector group that is currently in the link building state, set the polling start port number, the maximum number of ports supported by the vector group, the variable of the port number, and the memory space used to store the crosstalk coefficient, based on The polling starting port number can determine the first port in the vector group of the DISLAM that is currently in the link building state.

[0038] This embodiment further describes the method provided by the above-mentioned first embodiment by disclosing more technical features, Figure 4 It is a flow chart of the method for identifying the external serial-in port by the vectoring system provided by the second embodiment of the present invention, as shown in Figure 4 As shown, the method includes the following processing:
[0039] S101: the process starts;
[0040] The entrance of the software algorithm engine is on the network management, that is, the method can be executed by the network management.
[0041] S102: DSLAM network management initialization algorithm engine parameters, including the definition and initialization of the initial port number at the beginning of polling, the setting of the maximum port number max_port_num supported by the vectoring group, and the port_id setting used to identify the port number and serve as a loop intermediate variable. The port_id is The port number variable is used...
