S30810-Q2217-X100-6 Siemens HiPath/Hicom PBX Expansion Card

The Siemens S30810-Q2217-X100-6 is an STMD3 (Subscriber Trunk Module Digital) card designed for use in Siemens HiPath and Hicom private branch exchange (PBX) systems. This module provides digital trunk connectivity, enabling the PBX to interface with external ISDN or digital telephone network services.

The STMD3 module is typically deployed in enterprise telephony environments where reliable digital trunk connections are required for voice communications. It integrates within the modular architecture of Siemens communication platforms, supporting scalable trunk capacity as business needs evolve.

This is a legacy component from the Siemens telecommunications portfolio, which has since transitioned to Unify. While no longer in active production, the STMD3 remains relevant for organisations maintaining existing HiPath or Hicom infrastructure and requiring replacement or spare modules.
