The Multi-Tech SocketModem ISDN creates communication-ready devices by integrating BRI ISDN functionality and
S/T interface into a single, universal socket design. The space-efficient (1” x 2.5”) embedded modem provides bi-
directional communication bandwidth of up to 128K bps. This complete, ready-to-integrate modem dramatically
reduces development time and costs for system designers.
