ADSL2+ isn't up to the HD challenge
Triple play is where it's at for telecommunications providers or at least where they want to be. Having one bill for all your telecommunications needs isn't only appealing to consumers, cable Cos want to get your phone business and Telcos want your TV business, but the question is how? Lucky for the Cable Co's they have used coax for their networks which is inherently better than the voice grade
non-twisted pair the telcos have been using for years. While the telcos are rolling out fiber all over the country they are trying to use ADSL2+ to keep their customers happy in the mean time. This works pretty good for Internet access and even some TV, but not so great for HDTV, which of course the only thing that matters!
