Abstract
Provided are a communication system and a communication device capable of suppressing attenuation of a communication signal superimposed upon a control pilot line. This output circuit () sends a control pilot signal which has been generated at a voltage generation source () to an input circuit (). Between the control pilot line () and the ground line () of the output side of the output circuit (), a communication unit () is connected via a transformer (). Between the control pilot line () and the ground line () of the input side of the input circuit (), a communication unit () is connected via a transformer (). Between the output circuit () and the transformer (), a lowpass filter () is interposed. Between the input circuit () and the transformer (), a lowpass filter () is interposed.
