Description: This attribute represents the total number of NCP fields received by the CM.
What is docsIf31CmDsOfdmChanNcpTotalFields?
A 64-bit counter of the total number of NCP (Next Codeword Pointer) fields the modem has received on this downstream OFDM channel; NCP fields tell the receiver where the next MAC frame's codewords begin. Admins compare this against docsIf31CmDsOfdmChanNcpFieldCrcFailures to calculate the NCP error rate, which affects the modem's ability to correctly parse the downstream data stream.
Examples
