What does "CCAP Commanded Power in Excess of 6 dB Below..." mean?

"DRW = Dynamic Range Window

there is a Dynamic Range Window to which CM can adjust power. For e.g. you cannot ask CM to to go from 30dBmV to 50dBmV suddenly.  there is a window of 12dB which CM must follow.

basically, CMTS is asking CM to raise beyond DRW and CM is complaining he wont do it.

• DOCSIS 3.0 Dynamic Range Window (DRW)
  • During initial ranging on chs being added by TCC encodings, Cable Modem MUST cover entire Dynamic Range Window within 16 retries, leaving no power interval greater than 6 dB untried
  • So for DOCSIS 3.0, by commanding power to mid of window it allows to go either 6 dB above or 6 dB below, which will cover whole 12 dB window
  • DOCSIS 3.0 uses a per-ch Dynamic Range Window, whereas DOCSIS 3.1 uses a single Dynamic Range Window for all chs in TCC
  • DOCSIS 3.0 allows bit more flexibility to shift Dynamic Range Window slightly for each ch if need be
• DOCSIS 3.1 Dynamic Range Window (DRW)
  • CMTS normally administers Dynamic Range Window of 12 dB [DOCSIS MULPIv3.1] which is sufficient to accommodate plant tilts of up to 10 dB from lower to upper edge of US band
  • Since fidelity requirements are specified in flat freq conditions from top of Dynamic Range Window, it’s desirable to maintain Cable Modem Tx power levels as close to top of Dynamic Range Window as possible
  • DOCSIS 3.1 uses single Dynamic Range Window for all chs in TCC
  • Three types of Dynamic Range Window violations reported by BRCM DOCSIS 3.1 Cable Modem"
