The ConexantTMRH56D-PCI V.90/K56flexTM Host Controlled Modem Device Family supports high speed analog data up to 56 kbps, 14.4 kbps fax, voice/TAM, and speakerphone (optional) operation. The modem operates with PSTN telephone lines in the U.S. and world-wide.The modem is available with or without speakerphone support (see Table 1).
The modem is packaged in a single 144-pin thin quad flat pack (TQFP) that combines PCI Bus Interface (BIF) and Modem Data Pump (MDP) functions. This modem is pincompatible with the SoftK56-PCI modem, part number R6793 (see SoftK56-PCI data sheet Order No. MD231).
Host modem software is also provided.
Operating with +3.3V power, this device set supports 32-bit host applications in such designs as embedded motherboards and PCI half cards. Downloadable architecture allows updating of MDP executable code.
In ITU-T V.90/K56flex data mode, the modem can receive data at speeds up to 56 kbps from a digitally connected V.90 or K56flex-compatible central site modem. A V.90/K56flex modem takes advantage of the PSTN which is primarily digital except for the client modem to central office local loop and is ideal for applications such as remote access to an Internet Service Provider (ISP), online service, or corporate site. In this mode, the modem can transmit data at peeds up to V.34 rates.
In V.34 data mode, the modem operates at line speeds up to 33.6 kbps. When applicable, error correction(V.42/MNP 2-4) and data compression (V.42 bis/MNP 5) maximize data transfer integrity and boost average data throughput. Non-error-correcting mode is also supported.
All models support remote audio recording and remote audio playback over the telephone line interface using ALaw,
m-Law, or linear coding at 8000 or 7200 Hz sample rate to support applications such as digital telephone answering machine (TAM).<
