"\"This item provides measurements of the receive modulation error ratio (RxMER) for each subcarrier. Each subcarrier RxMER value consists of one byte which represents the RxMER value with range 0 to 63.5 dB in 0.25 dB steps. If some subcarriers (such as exclusion bands) cannot be measured by the CM, the CM indicates that condition by reporting a value of 0xFF for the RxMER for those subcarriers. Any measured RxMER value below 0 dB is clipped to 0 dB (0x00), and any measured value above 63.5 dB is clipped to 63.5 dB (0xFE). Mathematical notation for the calculation of RxMER is provided in [PHYv3.1]: 'Downstream Receive Modulation Error Ratio (RxMER) Per Subcarrier'. This table will have a row for each ifIndex for the modem. \"",
