The Zoom/Modem V.92 PC Card Plus Model 3075 is a high-performance 56K fax modem that plugs into the PCMCIA slot of a Windows laptop computer.
- The Zoom/Modem V.92 PC Card Plus outperforms V.90 modems. ITU V.92 is a new standard for dialup modems. It, and its companion compression standard V.44, makes communications faster, easier and more enjoyable. - The "automatic negotiation" or "handshake" at the beginning of a call can be over twice as fast with Zoom/Modem V.92 models than with V.90 modems.
- The new V.44 compression technology results in significantly faster Web browsing and download speeds. Upload speeds (before compression) with Zoom/Modem V.92 models can be up to 40% faster, too. As an added convenience, the Zoom/Modem V.92 allows an incoming phone call to be received without losing an Internet connection. These dramatic improvements in performance are available to Zoom/Modem V.92 users whose ISP (Internet Service Provider) has upgraded to the new standard. The Model 3075 is also fully compatible with the V.90 standard.
- The Zoom/Modem 56K V.92 PC Card Plus Model 3075's small size, easy installation, and rugged connector make it ideal for traveling - even worldwide! The Zoom/Modem V.92 PC Card Plus Model 3075 is furnished with the Zoom World Traveller Universal DAA software that allows the modem to work with phone systems in 185 countries.
- The Model 3075 includes V.80 capability for compatibility with H.324 standard point-to-point video telephony over regular phone lines. It also supports Group 3, Class 1 Fax.
- Additional features include PC Card Guard to protect against damage to the modem that can be caused by overvoltage. This condition may be caused by accidental connection to a digital PBX phone. Another protective feature is the industry leading ZoomGuard lightning protection. ZoomGuard is not only better than the "varistor" protection found on other modems, but also outperforms most standalone surge protectors.
