S30810-Q2141-X-13 Siemens HiPath 3000/4000 PBX Expansion Card

The Siemens S30810-Q2141-X-13 is an SLMA (Subscriber Line Module Analogue) card designed to provide analogue subscriber line connections within Siemens HiPath PBX telephone systems. This module enables the connection of analogue endpoints such as standard telephones, fax machines, and modems to the digital switching infrastructure.

The SLMA card is intended for deployment in Siemens HiPath 3000 and HiPath 4000 series communication platforms, where it serves as the interface between analogue devices and the core telephony system. Each module typically supports multiple analogue ports, allowing enterprises to maintain legacy analogue equipment alongside digital and IP telephony services.

As part of the Siemens enterprise communications portfolio (now under Unify), the HiPath series and associated modules such as the SLMA are considered legacy products. However, many installations remain in active service, creating ongoing demand for replacement and expansion cards to maintain existing infrastructure.
