Kazizuru Answer tone detection period. Request additional country profiles from a Conexant Sales Office. Using modem modulations to optimize modem datashewt for line conditions, the modem can connect at the highest data rate that the channel can support from 56 kbps down to bps with automatic fallback.

Full-duplex Receive and Transmit Mode. Datashwet DC electrical characteristics are listed in Table Shaping includes both acoustic and line echo cancellation. Escape sequence detection is disabled by an S2 Register value greater than Calculated voltage is applied to this output to control off-hook and DC VI mask operation. A maximum of 48 kbps upstream rate is supported with PCM upstream enabled, in contrast to a maximum of In the fax mode, the on-line behavior of the modem is different from the data non-fax mode.

Voice Transmit Mode supports playback of voice or audio data to the telephone line. The modem operates by executing masked code from internal Datasheeg.

Cc With PCM upstream enabled, data transmission supports sending data at line speeds up to 48 kbps. This feature c be used to quickly drop a modem connection in the event when a user picks up an extension phone line.

The following are trademarks of Conexant Systems, Inc. On-hook, Idle, waiting for ring Normal Mode: Table lists the ordering information.

When enabled, caller ID information date, time, caller code, and name can be passed to the DTE in formatted or unformatted form. Voice-call-first VCF before switching to a videophone call is also supported. In MNP 5, the modem increases its throughput by compressing data into tokens before transmitting it to the remote modem, and by decompressing encoded received data before sending it to the DTE. In addition, the modem supports remote telephone answering machine TAM and speakerphone.

If carrier is lost for a time greater than specified by the S10 register, the modem disconnects. The LSD is connected to a floating ground and can tolerate high voltage input compatible with telephone line and typical surge requirements.

This mode supports applications such as digital telephone answering machine, voice annotation, and recording from and playback to the telephone line. CXx Modem hardware interface signals are defined in Table Small, low-profile packages, reduced voltage operation, and low power consumption make this device set an ideal solution for embedded applications. For example, this feature allows set top boxes with an integrated CSMSP modem to give normal voice users the highest priority over the telephone line.

The modem can detect and qualify ring signals and process AT commands. The modem can be awakened by the host sending a single any character typically followed by an AT command or by the modem receiving a qualified ring.
