As far as I can say, FDCH is a true manual transcript (or as close to one
as we can get) while CCAP is a degraded manual transcript. Thus lacking
anything better CCAP could do as a poor substitute, but I see no reason
why it should be used as manual if FDCH is available. Since we are interested
in performance contrasts, both FDCH vs. ASR and CCAP vs. ASR are of
interest, although for somewhat different reasons. For me, manual = FDCH.
But of course, George has the final word.
