Embedded ISDN Modem

Universal Socket Benefits

Interchangeable communications devices
Quick-to-market
Global approvals
Easy migration to future networks

The SocketModem^® ISDN embedded modem creates communication-ready devices by integrating BRI ISDN functionality and an S/T interface into a single, universal socket design. The space-efficient (1" × 2.5") 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.

Integration Reduces Space, Power and Cost. The SocketModem ISDN embedded modem integrates the controller, data pump and S/T interface in one communications device. This integration requires low power, low real estate, and provides an overall reduction in costs.

Complete WAN Protocol Support. With support for a full-range of WAN protocols, including PPP, ML-PPP, MP+, V.120, X.75, raw HDLC, CLEAR (synchronous), CHAP MD5, PAP and Soft Bond you can connect to a variety of servers.

SocketModem ISDN Pin-out. The SocketModem ISDN embedded modem interfaces easily with existing devices through a standard serial interface. The serial DTE channel is capable of transfer speeds up to 230.4K bps and can be interfaced directly to a UART or microcontroller.

Universal Socket Connectivity.
Multi-Tech’s universal socket is a flexible, comm-port architecture that provides cellular, Ethernet, PSTN or Wi-Fi network access with interchangeable communications devices. This means you can utilize one system design and populate it with your connectivity device of choice accommodating multiple connectivity requirements. In addition, you are assured a seamless migration to future technologies.

Developer's Kit. The Developer's Kit provides the ability to plug in the communications device and use it for testing, programming and evaluation. The kit includes one development board with RS-232 DB-25 connector, universal power supply, RJ-45 jack, RS-232 cable, RJ-45 cable and Developer Guide CD.
