A docsis downstream is capable of 38.8 megs. A MC16C has one downstream. A UBR7246 loaded with 2-4 MC16C blades with a NPE225 will top out at 60-70 megs depending on usage because the that is about the amount of traffic a NPE225 can process. Switching to a UBR7246VXR chassis and a NPEG1 will allow you to max out the chassis. Using MC28Us will be even better, because they have a processor built into the card which allows them to be even more efficient.
