An excellent article in this month's LIGHTWAVE Magazine on Cable's entry into traditionally-LEC and ISP deployments. In fact, Cablevision's Lightpath division is a registered LEC in its own right: http://lw.pennnet.com/Articles/Article_Display.cfm?

That's how time-warner is doing it here in Maine. However, they've assigned voip to its own channel while digital channels occupy another and hdtv signals are compressed and on another, etc. Its a 1Ghz system. Everything on the system is IP including the control boxes. They also have certain video and PPV on demand as well. Very interesting system that serves as a model for the rest of the country. Whatever they do they roll it out here first and this system totally rocks. I regularly get downloads at 3Mbps.

Folks,

This is a great discussion. I'm interested in understanding these types of limitations in the context of HFC cable networks. In my opinion, HDTV channel bandwidth (30mhz?) , increased demand for voip, and growing demand for IP connectivity is going to stress the cable network model as well, forcing cable operators to convert everything to IP before going out across the wire. Any input is appreciated.
