UNIDENTIFIED COMMANDS Command Default \K Unidentified Proprietary AT Command Set DISTINCTIVE RING Format: AT [cmds] -SDR=a,b [cmds] Default: a = 0, b = 0 Range: a = 0 - 7, b = 0, 1 Description: Selects which distinctive ring signals the modem will respond to and how it will respond. a Bit a Value Function 0 0 Modem will not answer ring type 1. 1 Modem will answer ring type 1. 1 0 Modem will not answer ring type 2. 1 Modem will answer ring type 2. 2 0 Modem will not answer ring type 3. 1 Modem will answer ring type 3. Value Meaning b=0 Modem will display all ring types 2 and 3 as RING. b=1 Modem will display ring type 1 as RING1, ring type 2 as RING2, and ring type 3 as RING3. MODE SELECTION Type: Immediate Format: AT [cmds] #CLS=n [cmds] Description: Selects which mode the modem will operate in. Command Function #CLS=0 Modem will operate in data mode. #CLS=1 Modem will operate in fax class 1 mode. #CLS=8 Modem will operate in voice mode. SPEAKERPHONE OPTIONS Type: Configuration Format: AT [cmds] #SPK=x,y,z [cmds] Description: Sets various options for speakerphone functions. Command Function x=0 Microphone enabled. x=1 Microphone disabled. x=2 Microphone enabled with maximum gain, speaker disabled. y Default: 5 Range: 0 - 16 Unit: -2 dBm Description: Sets the attenuation level for speaker output in voice mode. A value of 16 will mute the speaker. z=0 Microphone gain set to 0 dBm. z=1 Microphone gain set to 6 dBm. z=2 Microphone gain set to 9.5 dBm. z=3 Microphone gain set to 12 dBm. SVD DATA BURST Type: Configuration Format: AT [cmds] -SMC=n [cmds] Description: Selects whether the modem will increase data throughput when no audio signal is detected during an SVD connection. Command Function -SMC=0 Data burst disabled. -SMC=1 Data burst enabled. SVD BANDWIDTH Type: Configuration Format: AT [cmds] -SMS=a,b,c,d [cmds] Description: Selects the configuration, throughput levels, and baud rate that the mode will attempt to use for SVD mode. Command Function a=0 SVD mode disabled. a=2 SVD mode enabled. a=3 Auto-detect correct mode. b,c=4800 Sets the minimum and maximum combined voice and data speed to 4800bps, respectively. b,c=7200 Sets the minimum and maximum combined voice and data speed to 7200bps, respectively. b,c=9600 Sets the minimum and maximum combined voice and data speed to 9600bps, respectively. b,c=12000 Sets the minimum and maximum combined voice and data speed to 12Kbps, respectively. b,c=14400 Sets the minimum and maximum combined voice and data speed to 14.4Kbps, respectively. d=0 Auto-detects correct baud rate. d=1 Sets ML288 baud rate to 2400 baud. d=2 Sets ML288 baud rate to 2743 baud. d=3 Sets ML288 baud rate to 2800 baud. d=4 Sets ML288 baud rate to 3000 baud. d=5 Sets ML288 baud rate to 3200 baud. d=6 Sets ML288 baud rate to 3429 baud. SVD MODULATION Type: Configuration Format: AT [cmds] -SQS=m,n [cmds] Description: Selects which modulation type the modem will use for SVD mode. Command Function m=0 Selects V.61 modulation. m=1 Selects ML144 modulation. m=2 Selects ML288 modulation. n=0 Modem will not auto-detect the correct modulation. n=1 Modem will auto-detect the correct modulation. VOICE DEVICE Type: Configuration Format: AT [cmds] #VLS=n [cmds] Description: Selects the I/O device for the DSP chip. Note: This modem may not support all options listed below. The #VLS? command will display the available options. Command Function #VLS=0 Telephone line and handset used for voice I/O. #VLS=5 Headset used for voice I/O. #VLS=6 Speakerphone used for voice I/O.
