Description: This attribute is the length of the OFDMA fine ranging IUC preamble in bits.
What is docsIf31CmtsUsOfdmaChanFineRngPreambleLen?
Reports, in bits, the length of the preamble used for the fine ranging Interval Usage Code (IUC) on this OFDMA upstream channel. A longer preamble generally gives the CMTS a more reliable timing/power reference during fine ranging at the cost of more overhead, so admins can use this alongside the guardband and subcarrier-count settings to understand how the channel's ranging region was tuned.
