FIELD: radio engineering, communication.
SUBSTANCE: invention relates to radio engineering and can be used in communication systems. A communication device comprises first communication means configured to transmit differential signals serving as first information over a first wire pair; second communication means configured to transmit differential signals serving as second information over a second wire pair; and third communication means configured to transmit third information by transmitting one of differential signals over the first wire pair and transmitting the other of the differential signals over the second wire pair, wherein spurious emission is suppressed.
EFFECT: improved noise-immunity of communication.
