210068: SWITCH SUBASSEMBLY.
SST-4P and SST-8P PCI adapters are intelligent, high-speed (up to 920k bps on each port) PCI expansion boards, which provide high performance serial I/O solutions for a PCI bus host computer. All port interfaces are standard RS-232, with full modem control and voltage surge protection on every pin. SST PCI adapters appear to the system host processor as memory.
That is, they are memory mapped devices. Each adapter is automatically mapped into system memory at the time of device driver installation. SST adapters occupy a PCI slot in the host computer and provide the intelligent functions to "off-load" the CPU from serial communications processing tasks.
This part is cataloged in the U.S. Government catalog under NSN 5930-00-138-6935, indicating validated use in U.S. government and defense logistics supply chains.
