S30810-Q2226-X-14 Siemens HiPath/HiCom PBX Expansion Card

The Siemens S30810-Q2226-X-14 is a DIUT2 (Digital Interface Unit Trunk 2) card designed to provide ISDN trunk connectivity for Siemens enterprise communication systems. This interface card enables connection to digital trunk lines, facilitating external voice communications through ISDN Primary Rate or Basic Rate connections depending on the specific variant.

The DIUT2 module is designed for deployment within Siemens HiPath and HiCom PBX platforms, serving as a critical component for businesses requiring reliable digital trunk interfaces. It slots into the system’s expansion chassis, providing the necessary signalling and bearer channel support for ISDN trunk operations.

This is a legacy telecommunications component from Siemens’ enterprise portfolio, which has since transitioned under Unify. Despite being a discontinued product line, the DIUT2 remains in demand for maintaining and expanding existing HiPath and HiCom installations where ISDN trunk connectivity is still required.
