Check the value of the DEDICATED_INSTALL variable to see what kind of site you are working with.
One easy way to tell if you have an advanced site is to check if any of your site's services are running on separate boxes from the main TeamForge application. This can only happen on an advanced site.
However, if your site has all its services running on the same box, it is not necessarily a dedicated site in the sense that we're talking about. You can have an advanced site on a single box.
If there is any doubt, look in the site's master configuration file.
