The IDC 100i provides Basic Rate Interface connections, with two 64-kbps channels for carrying data or voice and one 16-kbps channel for call setup and signaling. The adapter runs with Windows 3.1 or Windows 95, and the adapter works with common telephone switching systems and communications programs with support for standards including WinSock, PPP (Point-to-Point Protocol), and Multilink PPP.
The software also includes a pop-up support window that automatically tells users what to do when a problem arises. One thing you can't do with the adapter is make calls while continuing to download data, something that many of the more expensive ISDN adapter cards can do.
