RC9696AC

The Flockwell RC9696AC V.32N.42 bis Modem Device Set operates over a dial-up or leased line at communication speeds up to 9600 bps, and with data compression delivers effective throughput up to 38400 bps. The modem is compatible with CClTT V.32, V.22 bis, V.22, and V.21 recommendations, and Bell 212A and 103 modems. The RC9696AC supports global connectivity via multimode operation and includes V.42 error correcting and V.42 bis data compression protocols. The RC9696AC also supports MNP classes 2, 3, and 4 error control and MNP 5 data compression. The modem can also operate in non-error-correcting modes. A full-featured industry standard "AT' command set is implemented, which ensures operation with popular communications software packages. AT command extensions simplify the use of V.42, V.-42 bis, and MNP capabilities. The modem provides auto-dial, auto-redial and auto-answer capabilities, and can operate in both synchronous and asynchronous modes. The RC9696AC device set consists of a microcontroller unit a multi-protocol communications controller and an RC9696!12 modem data pump (MDP)module. The OEM adds memory (64k bytes ROM, 32k bytes RAM, and 2048 bits NVRAM), supporting components address demultiplex, chip select, data buffer, and line receiversidrivers}, line interface circuitry, and power supply to complete the modem. To aid in rapid product development, two complete modem evaluation boards are available-a parallel interface version and a serial interface version. The parallel version is a PC bus-compatible half card. It can operate in USlCanada or Japan using call progress and tone detect parameters selected by a hardware strap. For international versions, the RC9696AC-E (not described in this data sheet) is available. Additional modem information is described in the RC9696AC Designer's Guide (Order No. 855).
