S30810-Q2311-X300-C1 Siemens HiPath 3000/4000 PBX Expansion Card

The Siemens S30810-Q2311-X300-C1 is a DSCXL (Digital Subscriber Carrier Extended Large) module designed for Siemens HiPath and Hicom enterprise communication systems. This board provides digital subscriber line interfaces, enabling the connection of digital endpoints to the PBX switching infrastructure.

The DSCXL module is deployed within Siemens HiPath 3000 and HiPath 4000 series platforms, as well as legacy Hicom systems. It serves as a key component for expanding digital station capacity, supporting internal digital telephone connections across enterprise telephony environments.

This is a legacy Siemens product line, now part of the Unify portfolio following the brand transition. Despite being discontinued, DSCXL modules remain in active service across many existing HiPath installations and are sought after for system maintenance, expansion, and spare stock requirements.
