The question is: "Will I remain awake if I attempt to read that document?"
Probably not, it's more of a curiosity than anything else, I'm hunting down supported router models as it's interesting to find what the manufacturer has had to do, new DSL driver etc.
If you use an unsupported modem and there's a fault caused by sos/roc being enabled, they refuse to support you until you buy a new supported modem router.
VDSL modems that use an Intel or Lantiq chipset may no longer work or may require a firmware update to work.
