Abstract
A hybrid fiber coaxial (HFC) access network manager is formed to support a variety of functions related to the operation and management of an HCF access plant. The HFC access network manager allows for monitoring of the downstream and upstream transmission paths, and supports the sectionalization of faults. The monitoring can be achieved through a variety of techniques including, but not limited to, monitoring bit error rate (BER), frame error rate (FER), carrier-to-noise ratio (C/N), or any other suitable quality-related signal parameter.
