My understanding is that it was this feature of the DTx work that led to
this new undertaking. The point was that IF you make the trellis start a
known "determined" state (clock based), "syncing" could be easily
accomplished based upon a known state. It builds up from there...the DF
dependent upon "slicing", embedding new features/user data types, and a
whole lot more...an overhauled "physical framework" to work with.
