1 / 12 page Data Sheet Order No. MD205 March 31, 1998 FM209 and FM214 9600/14400 bps MONOFAX® Modem Family The Conexant™ FM209 and FM214 MONOFAX® modem family offers synchronous 9600 or 14400 bits per second (bps) half-duplex modems with error detection, voice and audio codecs, full-duplex speakerphone, automatic speech recognition, DTMF reception, V.23 full-duplex, Type I Caller ID and Type II Caller ID CAS detection. It has low power consumption and is housed in a single 128-pin Thin Quad Flat Pack (TQFP) device package. The modem's small size and low power consumption allow the design of compact system enclosures for use in both office and home environments. Table 1 lists the FM209/FM214 models and features. Group 3 Facsimile Modem The modem can operate over the public switched telephone network (PSTN) through line termination provided by a data access arrangement (DAA). The modem satisfies the requirements specified in ITU-T recommendations V.33, V.17, V.29, V.27 ter, V.21 Channel 2 (FSK), T.4, and meets the binary signaling requirements of T.30. The modem operates at 14400, 12000, 9600, 7200, 4800, 2400, or 300 bps. The modem supports the V.17 signaling rates of 14400, 12000, 9600, and 7200 bps using trellis-coded modulation (TCM). In addition, the modem supports V.27 ter and V.17 short trains. The modem can also perform HDLC framing according to T.30 at 14400, 12000, 9600, 7200, 4800, 2400, or 300 bps. A FSK flag pattern (7E) detector facilitates FSK detection during V.33, V.17, V.29, and V.27 ter reception. The modem includes a programmable single/dual tone transmitter, a programmable DTMF receiver, three programmable tone detectors (which operate concurrently with the V.21 Channel 2 receiver), and a ring detector. The transmit output level is also programmable. Voice and Audio Codecs (-V Option) The voice coder/decoder (codec) compresses voice at an average rate of 2.9 kbps or at a fixed rate of 4.7 kbps with near toll quality playback at various pitch synchronized playback speeds. An average rate of 2.9 kbps provides 24 minutes of stored voice messages in 4 Mbits of memory. This voice codec allows the host controller to efficiently store and playback digital incoming messages (ICMs) and outgoing messages (OGMs). The ADPCM audio codec compresses audio signals (music/voice) at 32 kbps or 24 kbps for highest fidelity coding and reproduction. The PCM audio codec allows the host controller to transmit and receive uncompressed audio signals.
