S30810-Q2929-X100-4 Siemens HiPath 3000/4000 PBX Expansion Card

The Siemens S30810-Q2929-X100-4 is an SLA16N analogue subscriber line module providing 16 ports for connecting analogue endpoints to Siemens PBX systems. This card enables the connection of standard analogue telephones, fax machines, modems and other POTS devices to the digital switching infrastructure.

The SLA16N module is designed for deployment within Siemens HiPath 3000/4000 and HiCom series private branch exchange systems. It serves as a critical interface between traditional analogue terminal equipment and the core digital switching fabric, supporting mixed telephony environments where legacy analogue devices must coexist with digital and IP endpoints.

This is a legacy product from the Siemens enterprise communications portfolio, which has since transitioned through the Siemens Enterprise Communications and Unify brands. Despite its discontinued status, the SLA16N remains in active service across many installed HiPath and HiCom systems worldwide, creating ongoing demand for replacement and expansion modules.
