The purpose of this table is for the CM to report its estimate of the downstream channel response. The reciprocals of the channel response coefficients are typically used by the CM as its frequency-domain downstream equalizer coefficients. The channel estimate consists of a single complex valued coefficient per subcarrier. The channel response coefficients are expressed as 16 bit two's complement numbers using s2.13 format. The CM samples are scaled such that the average power of the samples is approximately 1, in order to avoid excessive clipping and quantization noise. Summary metrics (slope, ripple, and mean) are defined in order to avoid having to send all coefficients on every query. The summary metrics are calculated when the corresponding MIB is queried. A Coefficient filename and trigger are provided to obtain the channel coefficients. This table will have a row for each ifIndex for the modem.
