With MGCP we're just using DSx Qos which is just services classification within
the packet cable standard. Still runs over the same docsis network as all other
traffic and not separated besides qos side of things.

We use a 64K reserved channel to set the call up, after that each call has its
own service flow that is QOSed.

We also have reserved BW in the CMTS for 911 calls so that they always get
through.

Where the modem resides in relation to 911 isn't really a factor as we go by
services address for the account, a customer could moved the modem to another
house across town and it will still work.

I know Time Warner has completely separate networks for voice and data, they
didn't even reside on the same CMTS from what I understand. Don't know of
anyone else doing it that way.

It's my jackleg appraisal -- I'm not an attorney much less an FCC specialist
attorney -- that that subjects your service to regulations and restrictions
that don't pertain to people who do it the other way; you are simply a VoN
carrier, competing with all the other VoN carriers like Vonage; if you *do*
give your own traffic priority, then you're violating... title II? Some 
net neutrality provision that they don't cause they're not *moving the calls*
"over the Internet".
