The Zoom/Modem V.92 PCI is a Plug-and-Play internal modem, which is easily installed into a PCI slot of a Windows 95, 98, Me, 2000 or XP computer. Performance of the Model 3025CF is enhanced by an on-board Digital Signal Processor (DSP) which performs complex modulating/demodulating functions. The DSP provides a more stable system and better performance than "soft" Windows-only modems. The Model 3025 is fully compatible with all features of the latest V.92/V.44 international standards and will also communicate at V.90 and slower speeds.
