An out of band communications apparatus includes first and second data lines arranged in a differential pair. The data lines convey high speed data within a first frequency range and out of band data within a second frequency range that differs from the first frequency range. The apparatus also includes a band pass filter coupled to the first and second data lines. The filter only passes the out of band data and blocks the high speed data. The apparatus also includes a device coupled to the band pass filter and configured to at least one of transmit and receive out of band data.
