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. Hands-free full-duplex telephone operation is supported in Speakerphone Mode under host datashest. After dialing, modem operation is controlled by fax commands.
Applies to types I and O unless otherwise indicated. The modem can blind dial in the absence of a dial tone if enabled by the X0, X1, or X3 command. The following modes in V. Connect to digital ground GND. Please send comments and suggestions to conexant.
Voice Receive Mode supports recording voice or audio data input from the telephone line. Used for factory test only. A maximum of 48 kbps upstream rate is supported with PCM upstream enabled, in contrast to a maximum of All devices are lead-free Pb-free and RoHS-compliant.
However, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltage. After mode entry, AT commands can be entered without aborting the connection. This significant improvement is most noticeable when browsing and searching the web since HTML text files are highly compressible.
Connect to base of Q An additional or modified country profile can be loaded into internal SRAM. Receiver operational amplifier datashet input.
Ia Electronic Inductor Feedback. The modem cannot process AT commands. Leave open for Voltages referenced to ground VSS. 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. Using modem 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 with automatic fallback.
DTR ON prepares the modem to be connected to the telephone line, and maintains the connection established by the DTE manual datasehet or internally automatic answering. TAM Mode is supported by four submodes: Shaping includes both acoustic and line echo cancellation. The modem can speed sense data with mark or space parity and configures itself as follows: Oa Electronic Inductor Capacitor.
The modem operates by executing masked code from internal ROM. The server must support quick connect profiles. When connected in V. The CX current and power requirements are listed in Table Currents are positive when flowing into the device.

The CXx current and power requirements are listed in Table Therefore, all inputs should daasheet connected to an appropriate supply voltage. 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. The modem can automatically determine the speed and format of the data sent from the DTE.
Leave open for normal operation. Answer tone detection period. Both power dissipation and device noise immunity degrades. In Tone Mode, all three tone detectors are operational. All dimensions in mm. In fax modem mode, the modem can dxtasheet in 2-wire, half-duplex, synchronous modes and can support Group 3 facsimile send and receive speeds of,and bps.
