... Introduction The CONEXANT RP56D, RP336D, and RP144D Modem Data Pump (MDP) families support data/fax modem, voice coding/decoding, optional full-duplex speakerphone, and optional AudioSpan (Table 1). Low voltage and small size support desktop applications. Downloadable architecture allows upgrading of MDP code from the host/DTE. ...
