A moca network fault detection method

Abstract

The invention discloses a MoCA network fault detection method, which obtains the uplink and downlink signal data generated after modulation by the front end of the MoCA network, and obtains its modulation map data; carries out bit loading on the modulation map data, so that each modulation map data corresponds to a frequency point , and the modulation mode of each frequency point corresponds to a bit value, different modulation modes correspond to different bit values, the higher the modulation mode, the higher the corresponding bit value; the lower the modulation mode, the lower the corresponding bit value; if The current modulation map data is set in one of the modulation modes, and the modulation mode of a certain modulation map data in the current modulation map data is equal to the set modulation mode, then there is no fault in the MoCA network; otherwise, the modulation mode of the current modulation map data If the modulation mode of a certain modulation map data is smaller than the set modulation mode, the MoCA network is faulty. Through the corresponding MoCA network frequency point, the fault at the location of the corresponding MoCA network frequency point can be detected, so as to facilitate the later maintenance personnel to accurately maintain and troubleshoot the fault.

Description

technical field [0001] The invention relates to the technical field of MoCA system network fault detection, in particular to a MoCA network fault detection method. Background technique [0002] MOCA stands for Multimedia over Coax Alliance, which is the Multimedia over Coax Alliance and an industry standard that provides broadband access and home network product solutions based on coaxial cables. MOCA equipment is widely used in the construction of radio and television IP networks. [0003] With the wide application of Ethernet access technology based on cable TV coaxial cable, the corresponding equipment is used more and more, but the supporting fault detection methods are quite rare, especially for network opening and line network faults. Due to different protocols, the existing network cable-based network performance test method cannot be applied to the MoCA system network fault detection in the coaxial cable network. Contents of the invention [0004] The purpose of ...
