First, there must be a link license. Second you need IMAT software, a spare DSU slot and an MC270xx card. How are we doing so far? If you don't have a link license, you're out of luck because Mitel isn't selling any new licenses for 2k. The IMAT software is available from MOL. If you've got everything together, call back for more info.
