A second generation very-high-bit-rate digital subscriber loop (VDSL2) configuration management model based on actual service application scenarios is provided, which comprises a VDSL2 line (310) and an upstream rate profile (320), a downstream rate profile (330), a power spectrum profile (340), a noise margin profile (360), an interleaving delay and impulse noise protection profile (350) associated with the VDSL2 line (310), wherein the VDSL2 line (310) is used to specify the upstream rate profile (320) and the downstream rate profile (330) and configure a power management state; the upstream rate profile (320) is used to configure the upstream data rate of the line; the downstream rate profile (330) is used to configure a downstream data rate of the line; the power spectrum profile (340) is used to configure the power spectrum density profile of a sub-carrier; and the noise margin profile (360) is used to configure an upstream target noise margin, a downstream target noise margin and noise margin parameters of the line. |
