Simline DA - ISDN to X.21 Converter

Demand for the Simline DA grew from a requirement to carry out video conferencing sessions over a secure ISDN basic rate network connection. A Brent secure telephone scrambles data sent over the ISDN network and provides the user with two X.21 ports for the connection of data terminals. Our Simline DA also has two X.21 data ports which connect to the Brent, and one ISDN basic rate network port for connection to the video terminal.
