●Overview
●The Conexant®SCXV.92, SCXV.34, and SCXV.32bis modems are worldwide operational modem device sets for embedded applications that support modulations up to V.92, V.34, and V.32bis, respectively (refer to Table 1-1). All modems also support V.44/V.42bis/MNP 5 data compression for greater data throughput, V.42 LAPM/MNP2-4 error correction protocol for increased data integrity and reliability.
