Both but mainly a cell level issue:
If you lose a cell, it will screw-up the AAL5 frame. Thus causing the
frame and/or CRC errors seen in sh int.
You are really moving some traffic. Is this PVC traffic going across
any links that may be congested? A DS3 perhaps? Need to find where the
cells are getting dropped if you can.
