Abstract

A system for operating a power line communications system that includes a plurality of network elements, which may take the form of repeaters (70), bypass devices (100), backhaul points (10), wireless backhaul devices, enhanced bypass devices, communication interface devices (50) and others. Two groups of network elements in the same electrical distribution system are isolated except for the selected communication link.
