The host can separately control volume, muting, and AGC in microphone and speaker channels. Received analog mono audio samples are converted to digital form and formatted into 8-bit unsigned linear PCM format for reading by the host.
If carrier is lost for a time greater than specified by the S10 register, the modem disconnects. Parameters are constantly adjusted to maintain stability with automatic fallback from full-duplex to pseudo-duplex operation. Minimum e Nominal Maximum Note 0. Applies to types I and O unless otherwise indicated. Digitized audio data is converted to analog form then output to the TXA output.
Position these capacitors very close to the VREF pin.
It may also be disabled. In fax modem mode, the modem can operate in 2-wire, cx25048, synchronous modes and can support Group 3 facsimile send and receive speeds of,and bps. Connect to emitter of Q through R Additional profiles may also be included. Leave open for The modem can detect and qualify ring signals.
C must be placed close to pins 2. Electronic inductor filtering capacitor. An unterminated input can acquire unpredictable voltages through coupling with stray capacitance and internal cross talk. Voice Transmit Mode supports playback of voice or audio data to the telephone line.
Clock specifications are listed in Table An additional or modified country profile can be loaded into internal SRAM. A maximum of 48 kbps upstream rate is supported when connected to a V. Calling tone is generated in accordance with V. The CXx current and power requirements are listed in Table In normal or error-correction mode, this inactivity timer is reset when data is received from either the DTE or from the line.
Outputs transmit signal and datashete matching signal; connect to base of transistor Q Place C near pin 1.

The modem features internal RAM memory that enhances the modem’s flexibility. 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. Using this method, the software can detect an incoming call, place the data connection on hold, and switch back to a data connection. Used for factory test only. R and C must be placed very close to pin 6.
On-hook, Idle, waiting for ring Normal Mode: 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”.

Default parameters support U. In the fax mode, the on-line behavior of the modem is different from the data non-fax mode. The CX Codec hardware interface signals are described in Table Low speed modulations such as BellA or V. CX Codec analog electrical characteristics are listed in Datasheeet This mode supports applications such as digital telephone answering machine, voice annotation, and recording from and playback to the telephone line.
Speech received from the telephone line is shaped, converted to analog form, and output to the speaker or handset. The modem’s internal RAM can be used to load new datassheet profiles, override existing country profiles or add customized firmware code. Quick Connect The quick connect function enables the modem to shorten cz20548 connect time of subsequent calls to a server supporting quick connect.
Call failure can be detected for reasons such as no dial tone, number busy, no answer, no ringback detected, voice rather than modem detected, and key abort dial attempt aborted by user. Position these capacitors very close to the VC pin. Shaping includes both acoustic and line echo cancellation.

Conexant makes no commitment to update the information and shall have no responsibility whatsoever for conflicts or incompatibilities arising from future changes to its specifications and product descriptions.
In addition, the modem supports remote telephone answering machine TAM and speakerphone. Automode operation in V.
The modem can sense speeds of,,,,and bps and the following data formats: The modem is connected to a fixed digital ground and operates with standard CMOS logic levels.
It’s a community-based project which helps to repair anything. Shape of Pin 1 indicator on the bottom of package can be different i.
