Zoom/FaxModem 56K PCI Dualmode
About the Zoom/FaxModem 56K PCI Dualmode

The Zoom/FaxModem 56K PCI Dualmode is a low-cost, high-speed V.90 voice faxmodem that plugs into a PCI slot of Windows 95 Pentium P133 or faster computers. Its on-board digital signal processor and PC host-based controller are software upgradeable for easy updates and maximum flexibility. The 56K PCI Dualmode incorporates both the V.90 ITU 56K Standard and K56flex, the most widely supported non-ITU 56K technology, to achieve download speeds nearly twice as fast as any conventional analog modem*. That means fast access to the Internet, World Wide Web, and local area networks (LANs) over standard phone lines.

The 56K PCI Dualmode automatically connects in ITU V.90 mode or K56flex for up to 56,000 bps send/36,000 receive data speeds as well as V.34 Plus 33.6 Kbps send/receive, or any other ITU International or Bell standard speed to achieve the fastest, most reliable connection possible. It is software upgradeable and includes Plug and Play for easy installation.

Zoom Dualmode faxmodems provide high-quality voice mail when used with a soundcard. Voice mail works with Microsoft Phone and applications that support TAPI-compatible voice or IS-101 commands.

The 56K PCI Dualmode also has Class 1, 14.4 Kbps send/receive fax for convenient printer-quality faxing to any faxmodem or fax machine. You can even "broadcast" your faxes to multiple recipients, schedule fax transmission, or forward them to another number.

All Zoom Dualmode models include V.80 capability for compatibility with H.324 Standard point-to-point videotelephony over regular phone lines and also support H.323 Internet applications including video conferencing.

All Dualmode models include ZoomGuard lightning protection. ZoomGuard provides superior protection against lightning, the number one cause of modem failure. ZoomGuard is not only better than the "varistor" protection found on other modems, but it also outperforms most stand-alone surge protectors.

Zoom/FaxModem Dualmode modems are made and supported by Zoom Telephonics, Inc., and backed by Zoom's outstanding seven-year warranty.

* 56K provides speeds significantly higher than 33,600 bps for over 80% of local phone lines. Typical speeds range between 42 and 54 Kbps (the current limit set by the FCC).

** Sound with video requires a soundcard with microphone input, ITU H.323-compliant software for Internet or network applications including video conferencing, H.324-compliant software for point-to-point videotelephony over regular phone lines, and the appropriate computer and operating system to run the application.
