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.

Subject: Residential BW Planning
I am trying to perform some capacity planning for some of our
residential pops, but the old calcs I used to use seem useless -- as
they were adapted from the dialup days and relied upon a percentage of
users online (~50%) and a percentage of concurrent transmission (~19%).
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
