[Prior Art] Today's xDSL technology (including ADSL, ADSL2, ADSL2+, VDSL, VDSL2, etc.) has already set off a boom in global broadband applications, especially in Europe and Asia, and has become a broadband network access. The mainstream trend. Each xDSL equipment manufacturer needs to perform a series of equipment performance tests during the R&D equipment process. The test items are divided into two parts: the physical layer (Physical Layer) and the upper layer (Higher Layer) performance test, due to the physical layer circuit of the XDSL device. - The transmission performance of the device is determined, so the xDSL device manufacturers have spent a lot of effort and time on the physical layer performance test. In the current xDSL physical layer performance test architecture, the dotted line frame shown in Figure 1 mainly connects the xDSL central office device to be tested and the xdsL remote (user end) device to be tested to the existing noise generator. 11.
