      DLM - The Process

      DLM platform was tweaked back in March if I remember right. DLM in a nutshell:

      - Two modes: profile optimisation ('PO') and monitoring;
      - Monitors the line 24/7, collates data twice per day;
      - If the line is not performing optimally/stable, then profile optimisation is requested;
      - This is the same profile optimisation that occurs on new lines;
      - Typically starts within 72 hours;
      - Still continues to monitor and collate data;
      - Sets a new profile based on the data anywhere between 1-6am;
      - Lasts anywhere from a few days to 10 or slightly more;
      - DLM now uses 3dB/6dB/7dB target downstream SNRs. Upstream target SNR remains unchanged;
      - It seems DLM tweaks impulse noise protection higher when first attempting a lower SNR;
      - If it's stable, then it'll lift the noise protection which will in turn raise sync speed without change in SNRs;
      - When DLM finishes, the settings are locked in unless manually changed;
      - SVBN customers: Sky can't set lower than 7dB target SNRs. Only DLM can do this;
      - Non-SVBN customers: SNRs are chosen from a drop-down menu. If DLM has set a profile with lower SNRs (3dB or 6dB), then Sky do have the option to choose them manually from the drop-down menu. However, if 7dB if chosen again, then the 3dB and 6dB disappear from the drop-down.

      Not much of a nutshell, but will hopefully clear this process up for people in the future.
