Cable broadband Internet access piggy-backs onto a pre-existing
cable television system. One or more of the cable channels
is given over to the cable broadband service.
Typically a number of users share each of the cable
channels carrying the broadband service.
Cable broadband provides a
duplex link within the cable infrastructure. Cable broadband
does not, therefore, require a separate back channel.
