Siemens S30810-Q2166-X000-05 Hicom 300H / HiPath 4000 PBX Card / Module

The Siemens S30810-Q2166-X000-05 is an LTUCX (Line Trunk Unit Control, Extended) board for the Siemens Hicom 300H and HiPath 4000 telephone switching system, confirmed via multiple independent telecom parts resellers (price-telecom.fr, quaintrefining.com) under the shared S30810-Q2166 order-code prefix. It provides the core interface between the system central switching unit and its peripheral line and trunk hardware, and works alongside subscriber modules such as the SLMAC analog line card, which receives its instructions from the operating system through the LTUCX board. Like the related LTUCA and LTUCE variants confirmed for this product range, LTUCX is one generation within the same LTU Control board family, distinguished by its extended interface capability. Tech-Star (UK-based, shipped worldwide) supplies this as a tested spare for organisations still running Hicom 300H or HiPath 4000 PBX installations, where original boards are long out of production.
