Infotron INX4400/USM

Abstract

The Infotron Intelligent Network Exchange with the User Security Module option (INX4400/USM) is a high capacity digital data switching system (front-end connection switch) that handles asynchronous and synchronous data transmissions. It uses distributed logic and master-slave hierarchy to transfer data and control signals between devices that interface with the INX4400/USM. The INX4400/USM interfaces conform to EIA RS232C (CCITT V.24/V.28), and CCITT V. 11 and V.35 standards. The INX4400/USM can include up to 4000 input/output interfaces and can consist of 64 nodes. Because the USM solely interacts with asynchronous devices, this evaluation only addresses asynchronous data transmissions.
