The SlimModem3™ family is based on Conexant’s newly developed SmartV(128) modem chipsets.  New features include V.44 Data Compression and V.92, 48kbps upstream data speed for more efficient and faster data throughput.  The modems also offer V.29 POS Fast-connect and reduction in power consumption.  This feature-rich modem module family is fully self-contained including built-in data pump, modem controller and on-board International DAA.

The SlimModem3™ is designed as a drop-in replacement for Conexant’s SocketModem™.

Standard features of the modem include data rates up to 56 kbps, 14.4 kbps fax, voice playback and recording. The modem also provides enhanced features such as Caller ID, Extension Pick-up detect, Remote Hang-up, DLG (Digital Line Guard) protection and 2nd Ring Detect.  The 2nd Ring Detect feature allows a method for ring detection to control zero (0) modem power operation, ideal for battery based systems.
