What is docsIf31CmtsUsOfdmaChanRangingBackoffStart?
Reports the initial random backoff window for retrying Ranging Requests on this OFDMA upstream channel, expressed as a power of 2 (0-16); a value of 16 at the CMTS means a proprietary adaptive retry mechanism is used instead. This is the ranging-specific counterpart to docsIf31CmtsUsOfdmaChanTxBackoffStart, which admins check when many modems are contending to range in on a channel simultaneously (e.g. after an outage).
