In the fax mode, the on-line behavior of the modem is different from the data non-fax mode. Minimum e Nominal Maximum Note 0. This prevents datasheeet biasing the input protection diodes and possibly entering a latch up mode due to high current transients.

MOH can be executed through either of two methods: Contact your local Conexant sales office for additional country support.

Voice-call-first VCF before switching to a videophone call is also supported. 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.

For technical questions, contact your local Conexant sales office or field applications engineer. Single-ended analog data output. Information in this document is provided in connection with Conexant Systems, Inc.

Parameters are constantly adjusted to maintain stability with automatic fallback from full-duplex dataeheet pseudo-duplex operation. Conexant makes no commitment to update the information and shall have no responsibility whatsoever for conflicts or incompatibilities arising from future changes to datazheet specifications and product descriptions.

Un-rectified voltage from telephone line used to detect ring. Voltages referenced to ground VSS. Automode operation in V. In Tone Mode, all three tone detectors are operational. This allows the modem to maintain compliance with U.

Hands-free full-duplex telephone operation is supported in Speakerphone Mode under host control. Small, low-profile packages, datadheet voltage operation, and low power consumption make this device set an ideal solution for embedded applications. All voltages referenced to ground VSS. Voice Transmit Mode supports playback of voice or audio data to the telephone line. An additional or modified country profile can be loaded into internal SRAM. When PCM upstream is disabled, data transmission supports sending data at line speeds up to V.

Low speed modulations such as BellA or V. This feature is available only with a connection to a server supporting Datasheett. The modem operates by executing masked code from internal ROM. No license, express or implied, by estoppel or otherwise, to any intellectual property rights is granted by this document. Using a string of commands, the modem negotiates with the datssheet to place the data connection on hold while the line is released so that it can be used to conduct a voice call.

All tone and pattern detection functions required by the applicable ITU or Bell standards are supported. Shaping includes both acoustic and line echo cancellation.

Ring detection frequency range. Active low input asserted to power down the CX Cx205448.
