Cablecom probably will offer greater bandwidths once they have switched to digital TV becaus of digital TV is capable of offering a multitude of TV programs over a single channel. And with DOCSIS 3.0 one can bundle channels for even more bandwidth. Needs new infrastructure (modems and uBRs) though.
I think CC has a big trafffic Problem. They must switch off many of the analog Channels, when they want have more Traffic. They use some bandwidths for the digital TV, and for HDTV they use for every Channel the Space of 2 analog Channels... ok... With the compression od 1,5 channels... I think this will be a bigger Problem... Xaver
