Are you sure you need all of that?

When I designed ADSL solutions ~15 years ago I built with Paradyne DSLAM 
with ethernet uplink, then we used rfc 1483 bridged over ATM, so no need 
for PPP, radius or anything. It was just IPoETHERNEToATM and all the 
regular IPoE mechanisms could be used (DHCP etc).

So we just bundled the DSLAM with an L3 switch and that was that. One vlan 
per customer which solved the customer isolation problem. Customer could 
run modem in either bridged mode or terminate the IPoETHoATM PVC on the RG 
itself.
