What are the different upstream frequency bandwidths that I can configure?
A. The bandwidths are 6 MHz, 3 MHz, and 1.5 MHz. Because subchannelization is possible, you can use combinations of each of these channelization schemes. For example, if you use three upstream ports, you can have one upstream set for 3 MHz and the other two set for 1.5 MHz. You cannot exceed 6 MHz total with these combinations.
