S30810-Q2901-X Siemens HiPath 3000/4000 PBX Expansion Card

The Siemens S30810-Q2901-X is an SLMO24 subscriber line module designed to provide analogue extension connectivity within Siemens HiPath and Hicom private branch exchange systems. This card delivers 24 analogue subscriber ports, enabling the connection of standard analogue telephones, fax machines, and modems to the PBX infrastructure.

The SLMO24 module is deployed within enterprise telephony environments where a mix of analogue and digital endpoints is required. It slots into the HiPath 3000 or 4000 series systems, or legacy Hicom platforms, providing scalable analogue capacity for organisations transitioning from older equipment or maintaining analogue devices alongside IP telephony.

As a legacy Siemens component, the SLMO24 remains relevant for businesses operating existing HiPath or Hicom installations that require expansion, replacement, or spare parts inventory. Siemens enterprise communications products are now part of the Unify portfolio, though these classic modules continue to be sought after for system maintenance.
