S30810-Q2266-X Siemens HiPath/Hicom PBX Expansion Card

The Siemens S30810-Q2266-X is an LTUCA (Line Trunk Unit Card Assembly) module designed for Siemens HiPath and Hicom PBX telecommunications systems. This card provides trunk line connectivity, enabling the PBX system to interface with external telephone network lines for inbound and outbound call handling.

The LTUCA module is typically deployed in enterprise telephony environments where Siemens HiPath 3000/4000 or legacy Hicom PBX systems are installed. It serves as a critical component for connecting the private branch exchange to public switched telephone network (PSTN) services or other external trunk circuits.

This is a legacy Siemens telecommunications component from the HiPath/Hicom product family, which has since been transitioned through the Unify brand. Despite being discontinued, these modules remain in demand for maintaining and extending existing installations where full system replacement is not practical or cost-effective.
