With 2 active SCBs (2+0 non-redundant or 2+1 redundant in a 960) you are capable of 120G per slot.
The worst case throughput in this case would depend on the cards. For single Trio MPC1 in would be 30Gbit per card (actual 31.7 to ~ 39 depending on packet mix) For dual Trio MPC2 it would be same per half card or 60G total. For quad trio 16XGE would be 30G per bank of 4 until use SCBE or better than 40G per bank of 4 I do not recall the specs for those DPCs, as we downchecked all DPCs for other reasons and held off deployment until the release of the MPC2-3D-Q cards.
