( DataSheet : www.DataSheet4U.com ) personal computing products V.92 Single-Chip ACF Modem with Optional CX20437 Voice Codec CX06827 Conexant’s CX06827 single-chip V.92 modem device set enables modem designers to develop modems for desktop PCs and Internet appliances. Features available with V.92 are quick connect, PCM upstream and modem-on-hold. The new V.44 standard is also supported. This new data-compression protocol delivers data rates faster than those achieved by the V.42 bis protocol. The device set supports analog data at up to 56 Kbps, analog fax at up to 14.4 Kbps, telephone answering machine (TAM)/telephony extensions and voice/speakerphone (optional), and parallel/serial host interface operation, depending on the model. V.92 Features Quick Connect This feature approximates the “always on” connection of broadband access solutions by enabling dial-up modems to complete the modem handshake sequence 30% to 40% faster than before. PCM Upstream Using a new modulation for upstream data (a variation of PCM), V.92 supports a maximum upstream data rate of 48 Kbps, as compared to 33.6 Kbps for V.90. At the maximum rate, this represents a 40% improvement in upstream throughput. Users will also see throughput improvements when uploading digital audio and image files. Modem-on-Hold Call waiting is a popular feature offered by many telephone companies around the world. Unfortunately, a call-waiting event may disconnect a modem when it is in use, frustrating the user and of...
