Abstract
A communication device for use with a power line communication system is provided. One embodiment forms a bypass device and comprises a low voltage coupler, a low voltage signal conditioner, a controller, a medium voltage modem, a first medium signal conditioner, an isolator, a second medium voltage signal conditioner, and a medium coupler. The controller may provide routing functions to give priority to certain types of data, control access to the network, filter data packets, process software upgrades, and provision new subscriber devices. In addition, the controller may monitor, process, and transmit traffic data, measured power data, errors, and other collected data.
