I mean that by using the revision A.1 You could have some troubles. Main reason is related to the Global Underrun (GUN) that often occours when many channels are active (we use continuosly 64 channels on one mcc). This issue has been repored by Motorola in its document "mpc8260cesumm.pdf" and finally soved in the revision C.2 (6K23A) Second issue, is related to the possibility of having a bit rotation into a time slot. This problem has never been reported by Motorola but it seems to be any more present in revisione C.2.
