Monitoring system for a hybrid fiber cable network

The present invention relates to a monitoring system for a hybrid fiber cable (HFC) communication network and, more particularly, to the use of a plurality of "test points", distributed through the network topology to locate and isolate sources of noise (such as ingress) within the network. A monitoring system for a HFC network includes a plurality of "test points" disposed at various locations throughout the network. Each test point is used to allow for the isolation of communication problems within the network (for example, ingress) and mitigation of the effects of the network problems. By distributing a plurality of test points throughout the topology of the network, only limited sections of the network need to be isolated at any point in time to address the particular communication problem.
