RYS102452/1 Ericsson Ericsson MD110 PBX Module

The Ericsson RYS102452/1 is an EPROM (Erasable Programmable Read-Only Memory) component designed for use with the ELU26 line unit board (ROF1375321/2). This R7A revision firmware module provides the essential programming and operational instructions required for the ELU26 subscriber line interface to function correctly within Ericsson telecommunications systems.

The ELU26 is an analogue subscriber line unit commonly found in Ericsson MD110 and BusinessPhone PBX systems. This EPROM stores the firmware that controls the line unit’s signalling, switching and subscriber interface functions, making it a critical component for maintaining system operation.

This is a legacy component supporting discontinued Ericsson PBX platforms. It remains relevant for organisations maintaining existing MD110 or BusinessPhone installations, where replacement EPROMs may be required for board repairs or system expansion using refurbished hardware.
