RocketModem II

Turbocharged 56K* V.90 Multimodem PCI Cards

The Comtrol RocketModem^® II is an integrated, multimodem, PCI-bus expansion card designed to provide remote access on an industry-standard application server or to build a custom data communications server using industry-standard open systems technology. Combining Comtrol's proven RocketPort multiport serial controller technology with industry-standard modem modules, the RocketModem II provides either four or six 56 Kbps V.90 Rockwell data and fax modems in one easily installed, easily configured package.

The RocketModem II incorporates a 36 MHz RISC processor dedicated to processing asynchronous serial communications, thereby maximizing performance and minimizing CPU utilization. Utilizing Comtrol's unique Application Specific Integrated Circuit (ASIC) technology means simplified installation, elimination of shared memory conflicts, and increased reliability.

Optimum 56K Performance

The RocketModem II modem card uses proven, industry-standard Hayes^®-compatible fax modem modules to support a full range of data protocols at speeds up to 56 Kbps carrier speed. These include V.90, K56flex, V.34, data compression. Support is also provided for Group 3 fax send-and-receive at rates up to 14.4 Kbps, including fax Class 1 and Class 2. Please see the Specifications for details and additional supported protocols.

RocketModem II enables a wide variety of remote access applications, including dial-out access to ISPs, dial-in access for mobile workers or telecommuters who require access to the corporate LAN or intranet, and enterprise fax capabilities.

* Due to FCC regulations, receiving speeds are limited to 53 Kbps. Actual speeds may vary according to phone line conditions.
