ZBA Family Highlights

Radically Easy to Use.  The MT5634ZBA-USB model uses the Universal Serial Bus (USB) standard to provide the easiest modem on the market to install. You don’t have to set IRQs and jumpers, or plug in an external power supply. Just plug it into a USB port on your computer. Windows 98 or Mac OS 8.5 will detect it automatically, and you can hot-swap this modem with other USB devices without restarting your computer or changing system settings.

Advanced Features.  The MultiModemZBA family provides powerful features that make it perfect for business use. All models support US Caller ID reporting and remote configuration. Serial port models also feature callback security, DTR dialing, and 11-bit operation. The voice model supports full-duplex speakerphone operation so you and a caller can talk and listen at the same time –without cutting each other off.

Integrated Voice, Data Communications, and Fax Software.  The bundled software for these modems has an easy to use graphical interface for use under Windows 95, 98, and NT®. Also included are a number of free value-added applications, such as a web browser, Internet telephony, and on-line services.

Comprehensive Service and Support.  The Multi-Tech commitment to service means we provide a ten-year product warranty and lifetime service that includes free technical support and 24-hour web site, FTP, and BBS support.
