Determines whether the MiniSlot Start and MiniSlot Length settings are automatically or manually configured.

Pilot Pattern and Bit Loading are not automatically detected.

Default: Enabled
Auto Detect Enabled  
 

The software detects the correct MiniSlot Start and MiniSlot Length settings for the burst allocation.
Auto Detect Disabled

 
 

Edit Opens the Docsis MiniSlot Allocation Editor.

  • MiniSlot Start sets the expected minislot start for the burst allocation.
    Default: 0
    Range: 0-236

    This setting is overridden when Auto Detect MiniSlot Start and Length is enabled.

  • MiniSlot Length sets the expected minislot length for the burst allocation.
    Default: 236
    Range: 0-236

    This setting is overridden when Auto Detect MiniSlot Start and Length is enabled.

  • Pilot Pattern sets the expected pilot pattern for the burst allocation. Use pilot patterns 1-7 for FFT=2048. Use pilot patterns 8-14 for FFT=4096.

    Also the range for minislot start and minislot length is 0..236

    Default: Pattern1
    Range: Pattern1-Pattern14

  • Bit Loading sets the expected modulation type for the burst allocation.
    Default: QPSK
    Choices: BPSK, QPSK, 8-QAM, 16-QAM, 32-QAM, 64-QAM, 128-QAM, 256-QAM, 512-QAM, 1024-QAM, 2048-QAM, 4096-QAM

  • Add Adds a minislot to the manually created list of minislots.

  • Delete Deletes the selected minislot from the list of minislots.

  • Apply Applies the edited list of minislots to the current DOCSIS 4.0 Upstream demodulation.
