SmartSCM SocketModem V.90/K56flex/V.34/V.32 SocketModem Family for Worldwide Data/Fax/TAM Applications The Conexanta SmartSCMa SocketModema with SmartDAAa technology supports analog data up to 56 kbps, 33.6 kbps, and 14.4 kbps, and analog fax up to 14.4 kbps. For most existing designs, the SmartSCM SocketModem is a drop-in replacement for the SF56D/SP, SF336D/SP, or SF144D/SP SocketModem with the exception of some voice features. This SocketModem (Figure 1) is also ideal for new designs due to its low profile and use of Conexant's SmartSCM Single Chip Modem with SmartDAAa. The SocketModem stores over 38 country profiles in memory and more can be added as required. Features As a V.90/K56flexa data modem (SC43 series), the SmartSCM SocketModem can receive data at speeds up to 56 kbps from a digitally connected V.90- or K56flex-compatible central site modem. Taking advantage of the PSTN, which is primarily digital except for some client modem to central office local loops, V90/K56flex modems are ideal for applications such as remote access to an Internet Service Provider (ISP), on-line service, or corporate site. In this mode, the SocketModem can send data at speeds up to V.34 rates. * V.17, V.29, V.27 ter and V.21 channel 2 * EIA/TIA 578 Class 1 and T.31 Class 1.0 commands * EIA/TIA 578 Class 2 commands As a V.34 data modem (SC34 series), the SmartSCM SocketModem operates at line speeds up to 33.6 kbps. As a V.32 modem, the SmartSCM SocketModem operates at line speeds up to 14.4 kbps. Error correction (V.42/MNP 2-4) and data compression (V.42 bis/MNP 5) maximize data transfer integrity and boost average data throughput up to 230.4 kbps. Non-error-correcting mode is also supported. As a fax modem, the SmartSCM SocketModem supports V.17 fax for class 1 or 2 send and receive rates up to 14.4 kbps. The SmartSCM SocketModem uses a Conexant CX88168 SmartSCM, in a 128-pin TQFP, and a Conexant CX20463 SmartDAA, in a 32-pin TQFP. Figure 1.
