Tayta,
Why not with an RMON probe or Analyser software,
filter on an average user (i.e average business user).
You could filter on port 25 for SMTP (email) and port
80 for HTTP. See what they generate i.e peak
usage/average usage and then multiply up by a 1000 and
add a safety factor on top.
My best guess for 1000 users would be an 8 to 10 Meg
pipe.
Cheers,
Phil.
