Abstract

Aspects of the present disclosure are directed toward a system that includes a plurality of endpoint devices. Each endpoint device can be configured and arranged to monitor a plurality of communication channels carried over power distribution lines for data communications. The endpoint can detect setup communications that contain an endpoint identifier (ID) matching the endpoint. The endpoint then stores or assigns the organization ID (obtained from the detected communications) to itself. The endpoint configures itself to respond to subsequent operational communications based upon the organization ID. A command center is configured and arranged to transmit setup communications to endpoint devices. The setup communications can include one or more endpoint identifiers and the organization ID. The command center can also transmit operational communications to the plurality endpoint devices, the operational communications including the organization ID.
