System Interface Unit board for Huawei SoftX3000/MSOFTX3000 softswitch and HLR9820 core network platforms.

The Huawei SF31WWSIU0 is a WSIU (System Interface Unit) board, part number 03050148, used within Huawei’s SoftX3000/MSOFTX3000 softswitch and HLR9820 core network platforms. As a system interface unit, it handles internal interfacing functions within the chassis, supporting communication between processing boards and other subsystems in the MSC-server/HLR frame. It is part of the same SF31 board family as the WHSC and WALU units found on the same platforms, confirming its role as a core-network control-plane component rather than a service/traffic-bearing card. Tech-Star (UK-based, shipped worldwide) stocks tested Huawei core network spares; enquire to confirm exact frame/slot compatibility.
