Hi Neil,
PPPOE Access Concentrator that can easily keep up with 100Mbit of PPPOE throughput at large sizes, and preferably all sizes. Any and all brands or thoughts considered.
Best bet is an ERX, for so many reasons. You could probably get away with a 7200 with an NPE-400 as a bare minimum, but you'd be happier with a NPE-G1 and almost certainly happiest with the ERX.
In addition, who would be the best people to validate a bit of equipment for this requirement (assuming we don't end up buying calibrated and certified test gear).
Validate? People? Certification of the smartbits\ixia or of the router you'll be using? I don't recall ever having our test beds validated at the vendor I used to work for, course we never sold any routers either, so that's neither here nor there... ;-) Cheers, b
