Have you ever tried Videosinferencing over ADSL?

Hi, my Name is Heinz Weber, I'm the telemedicine-coordinator of our University and as well of the German society of surgery. Apart from Video over ISDN we have been working a lot on Video over ATM and Video over IP. Now I was really interested whether there were some groups having tried out "Video over DSL" already. A second Question was where I could get a description of G.703-Standard and whether there are possibilities to transfer G.703-Data over IP Thank you and please subscribe me to your mailing-list
