Yeh, keep going on about the plus side and forget about the negative side (as usual).
As Igni posted.

SCDMA does indeed have a purpose, it is more resilient in the presence of burst noise that ATDMA, however horses for courses. If it were so evidently superior everyone would be doing it. They aren't.
