Genuine Siemens S42024-A1857-A2 FMX access multiplex system card. Tested spare for legacy Siemens FMX carrier/subscriber-access platforms. Tech-Star (UK-based, shipped worldwide).

The Siemens S42024-A1857-A2 is a genuine card from the Siemens FMX access multiplex platform, a PDH-based carrier/multiplex system Siemens produced for subscriber access and carrier transmission applications in fixed-line telecom networks. This unit is a supervision unit (SISA/SUE) within the FMX subrack system, forming part of the platform’s modular, card-based architecture where individual units handle line interfacing, port termination, supervision or carrier-multiplex functions. Genuine Siemens material code S42024-A1857-A2, consistent with the material-code numbering convention used across the FMX card family and its S42024 material-code series. FMX systems remain in service in some legacy access and carrier networks, and genuine spares support continued operation of existing installations rather than a full platform replacement. Exact compatibility depends on the subrack generation and configuration of your specific FMX installation. Tech-Star (UK-based, shipped worldwide) supplies genuine tested Siemens FMX spares to network operators and maintenance engineers. Get in touch to confirm fit for your configuration, request testing details, or discuss lead time before you order.
