If the DTE fails to react to the code, and the modem continues to detect Answer tone, the code is repeated as often as once every 0.5 second.bBusy Send to DTE when the busy cadence is detected. The modem sends the busy b code every 4 seconds if busy continues to be detected and the DTE does not react. This allows the DTE the flexibility of ignoring what could be a false busy detection.cCalling Tone Sent when the T.30 1100 Hz Calling Tone (Fax Modem) is detected. The modem assumes the calling tone is valid and sends this code only after 4 seconds of proper cadence has been detected. If the DTE does not react to this code, the code is repeated as often as once every 4 seconds.dDial Tone Sent in Voice Receive Mode when dial tone is detected after any remaining data in the voice receive buffer. The modem sends this code every 3 seconds if dial tone continues to be detected and the DTE does not react. This allows the DTE the flexibility of ignoring what could be a false dial tone detection.e European Data Modem Calling Tone Sent when the V.25 1300 Hz Calling Tone (Data Modem) is detected. The modem assumes that the calling tone is valid, and sends this code only after 4 seconds of proper cadence has been detected. If the DTE does not react to this code and calling tone continues, the code is sent again as often as once every 4 seconds.fBell Answer Tone Sent when Bell 2225 Hz Answer Tone (Data) is detected. If the DTE fails to react to the code and the modem continues to detect Answer tone, the code is repeated as often as every 0.5 second.hHung Up Handset Sent immediately when the modem detects that the local handset has hung-up.qQuiet Sent in Voice Receive Mode after any remaining data in the receive voice buffer when the silence detection timer (#VSP) expires and the has been voice data passed to the DTE.sSilence Sent in Voice Receive Mode after the silence detection timer (#VSP) expires and if valid voice has not been detected (#VSS).tHandset Off-Hook Sent one time when the local handset transition go off-hook.End of Stream This code is sent to denote the end of a voice data stream.Table 1 Code Sent to ModemMeaningTerminate Sent during Voice Transmit Mode to indicate that the DTE has finished transmitting a voice message. The Modem complete transmission of any remaining data in the voice transmit buffer before responding with the VCON message and entering Online Voice Command Mode.Cancel Sent during Voice Transmit Mode to indicate that the DTE has finished transmitting a voice message and wants the modem to discard any remaining data in the voice transmit buffer. The modem immediately purges its buffer, and then responds with VCON message entering Online Voice Command Mode.pPause Sent during Voice Transmit Mode to force the modem to suspend sending voice data to the selected output device. Any data currently in the voice transmit buffer is saved until either a resume (r), or cancel (), is received, in which case the data is lost. If a is received during the paused state, the modem processes it normally, and also automatically resumes transmission of the data left in the buffer (appended with ). Any other data received from the DTE while in this paused state is placed in the transmit buffer according to available space, with flow control active.rResume Sent during Voice Transmit Mode to force the modem to resume sending voice data to the selected output device. Any data currently in the voice transmit buffer is now played. Table 2 AT Voice Command Description ATA - Answering in Voice This command works similarly to the way it works in Data and Fax Modes. Result Code: VCON ATD - Dial Command in Voice This command will perform the dial action in Voice Mode.

No key abort is allowed. Dual or Single Tones: These are represented by a substring enclosed in square brackets ([ ]) within the parameter. Each such substring consists of three sub-elements corresponding to 2 frequencies in Hertz (0, or 2000-3000) and a duration (ASCII decimal in units of 100ms). Varying DTMF Digits: This is represented by a substring enclosed in curly braces ({ }) within the parameter. Each such substring consists of two sub-elements corresponding to a DTMF digits (0-9, A-D, *, #), and alternate duration in units of 100ms. Parameters: The tone generation consists of elements in a list with each element separated by commas. Result Codes: OK Command to play tones on currently selected device is accepted. ERROR Command was not issued in Online Voice Command Mode or string is grammatically incorrect. #VTX - Voice Transmit This command set the modem in Voice Transmit Mode. The #VLS command should have been previously issued correctly. Parameters: None Result Codes: CONNECT When voice transmission by DTE can begin. ERROR If #VLS=0 and output device is not connected. %P - PTT Testing Utilities This facility testing of signal levels provides a continuous signal when the modem is in IDLE mode. This allows the user to initiate a series of signal that are necessary for PTT approval. These signals are answer tone, carriers, modulation, and other pertinent signals. A selected test will be terminated when any keyboard character is entered. The followings are command's description. Note: For DTMF, the transmit level is -10dBm for low band and -8dBm for high band, inter digit delay is fixed at 70ms. All other transmit level is adjustable according to the setting of register S91 (from -10 to -15dBm).
