I know QFwdToDNA might not be so clear but if my memory serves most of them are quite self-explanatory. I guess you could always check the corresponding call report entry if you see a CDR that you do not understand.Yes, I had already read that document, but it says nothing about the codes themselves. The information you sent is good about QFwdToDNA but what about the rest of the codes.
