Win2000 Terminal Server - 56k connection

Hi,

I want to add a terminal server to allow a couple remote users to access our network application. The problem is we only have a 56k line available here. No High speed connection is available so is a 56k (pc client)to 56k (Terminal Server) is fast enough considering that 2 or 3 simultanious connections will occur at the same time?

Thanks in advance.

Steve
