Connect to base of Q C must be placed close to pins 2.

Conexant strives to produce quality documentation and welcomes your feedback. Leave open for Using datasheer modulations to optimize modem configuration for line conditions, the modem can connect at the highest data rate that the channel can support from 56 kbps down to bps datashfet automatic fallback.

In the command state, the modem ignores RTS. The server must support Modem-on-Hold functionality. Connect to emitter of Q through R In addition, the modem supports remote telephone datazheet machine TAM and speakerphone.

The following modes in V. The modem can sense speeds of,,,,and bps and the following data formats: R and C must be placed very close to pin 6.


The modem can detect and qualify ring signals. Country-dependent modem parameters for functions such as dialing, carrier transmit level, calling tone, call progress tone detection, answer tone detection, blacklisting, caller ID, and relay control are programmable. Position these capacitors very close to the VC pin. DTR ON prepares the modem to be connected to the telephone line, and maintains the connection established by the DTE manual answering or internally automatic answering.

Leave open if not used. Leave open for normal operation. Un-rectified voltage from telephone line used to detect ring.

Device is marked A on the package Figure Receiver operational amplifier inverting input. Refer to applicable reference design for exact component placement and values. Speakerphone operation is entered during Voice Online Command mode after completing dialing or answering. Actions resulting from such failures can include specification of minimum inter-call delay, extended delay between calls, and maximum numbers of retries before the number is permanently forbidden “blacklisted”.


This mode supports applications such as digital telephone answering machine, voice annotation, and recording from and playback to the telephone line. The dictionary is dynamically updated during normal operation.


Industry standard and shortened answer tone B and V. Used for factory test only. Some AT commands are still valid but may operate differently than in data adtasheet mode. The LSD is connected to a floating ground and can tolerate high voltage input compatible with telephone line and typical surge requirements. Calculated voltage is applied to this output to control off-hook and DC VI vx20548 operation.

Escape dxtasheet detection is disabled by an S2 Register value greater than Default parameters support U. The modem features internal RAM memory that enhances the modem’s flexibility. Voice Transmit Mode supports playback of voice or audio data to the telephone line. The modem connects to host via a logical V. Input signals should never exceed the voltage range from
