  • Patent number: 9197886
    Abstract: A method implemented in a computer system for detecting performance degradation in a hybrid fiber-coaxial (HFC) cable plant having customer premises equipment (CPE) elements, active elements, and passive elements. The method collects radio frequency (RF) metric values, computes absolute deviation values of the RF metric values from reference RF metric values, computes relative hierarchical deviation values of the RF metric values, and computes relative peer deviation values of the RF metric values. The method sends an alarm message to an operator when the absolute deviation value, relative hierarchical deviation value, or relative peer deviation value for any element exceeds a threshold value.
    Type: Grant
