So you may have to replace the splitter with a MOCA 2 rated splitter.Also any other splitters in the cabling will have to be replaced. Unless it is MOCA 2 rated, it likely will not allow the MOCA 2 modem signals to pass through. If you are starting from a digital cable installation, the only question is the specific frequency range of the cable co.'s splitter. With two way communication required for digital cable and for MOCA, the splitter has to pass signals in both directions. Most cable simple installations are a 'star' in physical arrangement all meeting at a common splitter that takes as input the cable company's signal from outside the house. Most have a pass through port for analog cable tv / antenna signal. They convert an ethernet based signal on twisted pairs into a signal on a coax cable and vice versa.
