S30810-Q2187-X-3 Siemens HiPath/Hicom PBX Expansion Card

The Siemens S30810-Q2187-X-3 is a SIUX2 subscriber line interface unit designed for use in Siemens enterprise communication systems. This module provides analogue subscriber line connections, enabling the integration of analogue telephones and devices into digital PBX infrastructure.

The SIUX2 card is intended for deployment within Siemens HiPath and Hicom PBX platforms, serving as an interface between analogue end devices and the digital switching fabric. It supports multiple subscriber ports, allowing organisations to maintain analogue telephony services alongside digital and IP-based communications.

This is a legacy component from the Siemens enterprise communications portfolio, which has since transitioned to Unify. The SIUX2 remains relevant for organisations maintaining existing HiPath or Hicom installations and requiring spare or replacement modules to support ongoing operations.
