I didn't mean I didn't know the answer - I meant I couldn't say the answer.
:)  There are cable operators who still don't do dynamic qos control at the
cmts.  Even some that both your and our equipment's in as well, I think.
(but I don't track them, so I could be wrong there)

Yeah, it's been a slow rollout for the all-IP LI.  It would have been faster
I think if there had actually been standards for all the LI interfaces
earlier, for more than just packetcable, and if more of the SPAF/DF vendors
supported them.  So far I think we've had to do 5 different
pseudo-proprietary LI interface protocols, which is nuts.
