You speake correctly on some of this.  Qwest has moved from CAP to DMT,
the 675 only does CAP.  I've also heard that in some COs (I connect to
Denver Main) you get CAP whether you like it or not. But it looks to me
like the Cisco 675 does do PPPoA.  From the Cisco 675 command line:

I assume that I can do something like this:
http://www.cisco.com/en/US/products/hw/routers/ps295/products_configuration_example09186a0080093e3b.shtml

to get the C675 to just pass whatever frames/packets/cells it gets on the
DSL side through to the ethernet side, but after that, what do I make
the Linux box ethernet interface do?  PPPoE and PPPoA seem like the obvious
candidates, but does anybody know for sure?  I'd rather not incur a spanking
from Qwest on this, and as I see it, they really don't need to know what
happens in my basement - that's my side of the demarc box.
