It is not a flat ribbon cable.  These are discrete wires.  The cable supplier has indicated that the equipment is properly maintained and can't explain the reason for this occurring.  The manufacturer of the equipment has no explanation at this point, either.  This needs to be resolved, but at the moment my focus is determining whether this is causing the intermittent failure, and I need known good cables to do that.

Is this a flat ribbon cable. Are the cutting blades sharp? A dull blade can pull on the copper strands and break one or more.

The wires appear to be broken when the IDC takes place.  Instead of just piercing the insulation, I think it is contacting and breaking the wire.
