3 / 12 page MD205 3 Selectable error correction coding allows storage in audio grade RAMs (ARAMs). Echo cancellation techniques employed during playback allow DTMF, Type II Caller ID CAS detection, and tone detection during voice/audio codec operation to support user selectable features. Dual or single tone transmission is supported. The coder can record messages from either the primary or secondary IA. Speakerphone (-S Option) The full-duplex speakerphone provides hands-free telephone conversation employing acoustic and line echo cancellation and supports intercom conversation employing dual acoustic echo cancellation. The optional half-duplex speakerphone provides hand- free telephone/intercom conversation with exceptional high gain. The speakerphone algorithm constantly adjusts its parameters to deliver the best performance during real-time conditions, allowing automatic fallback from full-duplex to pseudo-duplex. The host controller can easily set up the speaker mute, microphone mute, automatic gain control (AGC) enable/disable, microphone level, line level, speaker volume, tone transmit, and handset functions. Conversation recording and message playback are supported during the speakerphone operation. DTMF detection, Type II Caller ID CAS detection, and three tone detectors are also supported. Automatic Speech Recognition (-R Option) Automatic Speech Recognition (ASR) consists of Speaker Independent (SI) North American English isolated word recognition for a predefined 69 word vocabulary list, Speaker Dependent (SD) isolated word training, and SD isolated word recognition functions. V.23 Full-Duplex Modem and Caller ID Both full-duplex transmit and receive (with asymmetric 1200/75 bps connection) and half-duplex (1200 bps) asynchronous V.23 are supported, as well as both serial and parallel interfaces to the modem. The V.23 algorithm includes an optional, programmable, receive compromise equalizer which is active in both V.23 and Caller ID modes. Common applications for V.23 include France's Minitel and Japan's Lowest Cost Routing. General Purpose Output (GPO) and General Purpose Input (GPI) pins are available for host assignment. Additional design information is described in the FM209 and FM214 MONOFAX Modem Family Designer's Guide (Order Number 1175). Table 1.
