[c-nsp] Peoples experiences with the 3825

[Ian MacKinnon]

Hi Tom,

The quick product guide says a 3825 will top out at 179.2Mbps

http://www.cisco.com/web/partners/downloads/765/tools/quickreference/routerperformance.pdf

This is usually with no features turned on

3845 will go up to 256M

Are you looking at a POS interface to connect to the 155 ring? Can you 
even get a POS Network Module?
