We have calculated our customers peak b/w usage between 20 and 60 kbps/user, spread across a wide variety of users and wide range of speeds (128/128 up to 15000/1000 kbps). You only need a few heavy users to skew things. But 400 at 4 Mbps would make me think that 20 to 30 Mbps would be sufficient.

My present scenario involves a micro-pop terminating 250 residences where users are expecting 4 mb/s. So I am looking for some baseline to begin at, so I am wondering what others are doing. Any thoughts are appreciated. Thanks --steve
