Well they are out as we (ACC) have deployed them and the have worked well so far.  We have had a couple of bug to date and Ascend has addressed them quickly.  As for them being new they have been around for two years but I do agree that they need some polishing on the router management side.

 Why, you know where to get one?  And even if they were out, I'm not sure
I'm want to deploy anything in a 60 node network pushing that much data
which was so new.
