Page 4: Overview
Microtronix Access X.25–TCP/IP Gateway 1 Overview The Microtronix Access X.25–TCP/IP Gateway provides conversion between X.25 and TCP/IP devices, or X.25 encapsulation over TCP (XOT). In addition, raw synchronous and serial terminal servers may be configured. A web interface allows for configuration and monitoring from any Internet browser, and telnet/SSH servers allow for connecting to the command line interface for additional management. -
