Each node in a hierarchical network regularly checks to determine whether its network connection is intact. If not, it autonomously communicates with other nodes in the physical neighborhood, using wireless capability also included at each node. It first searches for a wireless path to its immediate neighbors in the hierarchy attempting to reach a working node connected to the same distribution point. The nodes collect, store and exchange connectivity data on neighboring nodes. One member of a group of nodes that have exchanged connectivity information is selected to transmit a connectivity report to network control center. If not itself connected to the hierarchical network, the selected node can use the connection to the closest working node and its broadband connection to the network control center to inform the network operator of the fault and its likely location.
