Introduction

The Conexant? RH56D-PCI V.90/K56flex? Host Controlled Modem Device Family supports high speed analog data up to 56 kbps, 14.4 kbps fax, voice/TAM, and speakerphone (optional) operation. The modem operates with PSTN telephone lines in the U.S. and world-wide. The modem is available with or without speakerphone support (see Table 1).

The modem is packaged in a single 144-pin thin quad flat pack (TQFP) that combines PCI Bus Interface (BIF) and Modem Data Pump (MDP) functions. This modem is pin-compatible with the SoftK56-PCI modem, part number R6793 (see SoftK56-PCI data sheet Order No. MD231).
