The Ericsson RYS102328 is an MX PROM DSU (Programmable Read-Only Memory Data Storage Unit) revision R8A, designed for use within Ericsson’s AXE family of digital telephone exchange systems. This module provides firmware storage and execution capabilities essential for system operation and processor functions.

The MX PROM DSU serves as a critical component in AXE switching infrastructure, storing system software and configuration data required for exchange operations. These modules are integral to the control and processing subsystems within Ericsson’s telecommunications exchange architecture.
