There is a useful paper here. Please note that it refers to DOCSIS not EURODOCSIS; so the throughput quoted can be increased to 8/6 of the value quoted in the paper.
Where does the physical restriction come in as far as what the modem can handle? Could the vmng300 theoretically handle 1gbit as long as each of the 4 channels ran at something like 300mbit and it could handle the power requirements?
