It depends on what type of conferencing you want to do. Typically a min of 128kbps (or 1 ISDN line) is required for point to point video conferencing. If you want to do Internet and Mbone type conferencing, then a T1 is really the min. ADSL or a simular technology would be ideal for Internet and Mbone combination link. What I would look into is finding out what ISPs are wired to the same telephone switching office (usually called the central office) as you. In downtown Chicago, there should be an ISP in the same central office as you. Then call Ameritech and find out how much a ``dry circuit'' between you and one of these ISPs costs and how many K-ft the circuit is (finding someone inside of Ameritech that knows what a dry circuit is may take a little while). I would then contact PairGain (http://www.pairgain.com) and figure out what the best modem combination would be for you. You should be able to set up, at a min, a 384kbps connection between you and your ISP for minimal cost -Jim
