[cisco-bba] Ethernet/atm dslam aggregation

[Tassos Chatzithomaoglou]

I have read that the MWAM enables the 7600 to support up to 32,000 active simultaneous subscriber 
(LNS) sessions when equipped with a single MWAM. A single 7600 chassis can house up to four MWAMs so 
does this means 32,000 x 4 sessions per chassis?

On the other side Cisco 10000 supports 60,000 PPPoX sessions but there is no reference for LNS, only 
for LAC.

So, what do you think would be the "best" platform in terms of:

1) L2TP termination (LNS)
2) PPPoX termination
3) PPPoX termination & LAC forwarding

if we use :

1) ethernet based dsl aggegation
2) atm based dsl aggregation
