I'm in the process of doing a comparison between the newer 2800 (2811 to be exact) vs. a 3725. I am finding (or atleast it appears) that it is apples to oranges. I noticed that I can find things like "packets per second" for the 3725, but the 2800 series talks about lots of slots and abilities for things like VoIP. Can someone help me to understand the difference between what they are calling an Access Router (3725 etc) and a Multi-Service Router (2800 etc..)? I consult for a wireless ISP and which has currently a 45Mbps 802.11A backbone. Right now is is a switched backbone with 2611XM's doing InterVLAN routing. We are moving to a routed network and feel we need to upgrade the routers.
