Both the hybrid coax fiber box and the telephone companies' digital loop carriers deployed to extend the CSA of the local plant technically perform the same purpose except that the CATV box is trickier to design and maintain because it has to segregate the video stream from the voice signal.

The greatest advantage that cable modems have is that of a shared bus topology.
