The Hayes Accura V.92 PCI Softmodem 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.

Benefits of V.92/V.44 include:
Faster negotiation: most modems call the same Internet service number every time.
V.92 modems save the connection profile to significantly reduce connection time.
Improved data compression: the old V.42bis compression standard was set before the advent of the World Wide Web! The newer V.44 standard is designed for the kinds of content seen on the Web today and can noticeably improve your download speeds.
Faster upload speeds: V.92 can send e-mail and attachments up to 40 percent faster than V.90 modems.
Modem-on-Hold: allows you to answer an incoming call without losing an Internet connection on the same line

In addition to the latest data communications technology, the Hayes Accura V.92 PCI Softmodem includes:
- Voice mail support when used with a soundcard
- Send and receive fax support
- Robust lightning protection to guard against the leading cause of modem failure
