Abstract: In one embodiment, a method includes transmitting pulse power on two wire pairs, the pulse power comprising a plurality of high voltage pulses with the high voltage pulses on the wire pairs offset between the wire pairs to provide continuous power, performing low voltage fault detection on each of the wire pairs between the high voltage pulses, and transmitting data on at least one of the wire pairs during transmittal of the high voltage pulses. Data transmittal is suspended during the low voltage fault detection.

Abstract: A data packet communication system is described, which can be implemented as a physical push based data packet communication device, such as a router, a gateway, or a controller circuit coupled to a router or a gateway adapted for controlling data packet communications. The data packet communication system is adapted to evaluate network capacity of each of the multiple networks at the time of a monitored communication event and assigns data packets accordingly.

Abstract: An improved data packet communications approach is described that is adapted for communications across unreliable connections. In particular, the approach can be implemented as systems and methods for a networked router device configured to monitor communication characteristics and to group the connections into various tiers based on their communication reliability data. When a new packet is to be communicated, the grouped connections are utilized in aggregate to meet a target transmission reliability probability (e.g., target value or a band of values).
