This is my solution, since cable and phone guys are installing identical networks. The head-end or central office starts with switched ATM. ATM goes to neighborhood analog cables with up to 500 subscribers.
So my proposal -- let the phone guys put the ATM in and then connect to the subscriber cable in the neighborhoods. Then you've got alternative information sources. But that begs the question of symmetry. Is there back channel capacity? Is there an ability to communicate from set top to set top to do the things that should evolve, virtual video and virtual VR between sites.
