Completely different system. There are IDC systems that use simple quarter-turn split barrels, not even close to the 4010/4011 system.

I can't tell from the picture, but they could be full-turn traditional screw terminals where the jumper is stripped and wrapped around the screw shank. 3M, Corning and HUB make them all day long and they are in wide use here in Verizon territory. They also use a simple flat-head screwdriver to tighten the screw.

White/orange terminal marking in cross connect cabinets has been quite the norm for many years, regardless of the manufacturer or termination method. Others use many other colors as long as tip and ring are easily-identifiable.
