S30810-Q2227-X400 Siemens HiPath 3000/4000 PBX Expansion Card

The Siemens S30810-Q2227-X400 is an SLMAV24 subscriber line module providing 24 analogue extension ports. This card enables connection of analogue telephones, fax machines, modems and other analogue terminal equipment to Siemens HiPath communication platforms.

The SLMAV24 module is designed for deployment within Siemens HiPath 3000 and HiPath 4000 series PBX systems. It serves as a key expansion component where organisations require additional analogue line capacity for legacy devices or specific telephony applications that demand traditional analogue connectivity.

This is a legacy product from the Siemens enterprise communications portfolio, which has since transitioned to Unify. The SLMAV24 remains relevant for organisations maintaining existing HiPath installations or requiring spare modules for operational continuity.
