Abstract
A transmission system includes a first device and a second device remote from the first device. The first device transmits electrical energy to a transmission line during a power provision phase, generates and transmits data symbols to the transmission line during a downstream transmission phase, and receives data symbols from the transmission line during an upstream transmission phase. The second device receives the energy from the transmission line during the power provision phase, receives the data symbols from the transmission line during the downstream transmission phase, and generates and transmits the data symbols to the transmission line during the upstream transmission phase, and the second device generates and transmits data symbols by shorting or disconnecting the transmission line. A method of transmitting electrical energy from the local device to the remote device, and communicating data symbols between the local and remote devices is also disclosed.
