The USRobotics 56K* PCI Express Faxmodem (PCIe 1.1) is a single lane (x1) express card with both full height and low profle brackets and will ft into any available PCI Express slot. It is also broadly compatible with Windows including 64 bit and server systems, using the CPU of the host computer for high compression throughput due to direct parallel access. The PCI Express Faxmodem is fully compatible with V.92 and lower rates, making it ideal for compact POS solutions that only require V.34.
