: For backward compatibility and legacy support, the chip integrates 32 Quadrature Amplitude Modulation (QAM) channels.
Note: Specifications regarding exact channel counts (e.g., 32x8 vs 32x4) can vary slightly depending on the specific firmware configuration applied by the hardware manufacturer, but the BCM3392 is universally classified as a high-throughput DOCSIS 3.1 solution.
: The BCM3392 supports four independent Orthogonal Frequency Division Multiplexing (OFDM) downstream channels. This is a massive leap from the two OFDM channels supported by the legacy BCM3390.
