| Voice commands (TAM) related to the telephone answering machine) |
| Command |
Description |
| + Vtd = N |
The duration of the beep. At + vtd = n sets the default retention time for generating DTMF/audio (in 0.01 seconds ). |
| + VTS = N |
Generate DTMF and audio in voice mode. The at + VTS = n command enables the modem to generate the specified DTMF audio sequence of the parameter string (or other audio, such as dial tone, busy tone, or static noise ). For more information about audio strings, see is-101. |
| + VLS = N |
Select a simulated source/target. Tam supports the following is-101 simulated source/target configurations: N= 0 the modem is down and the local phone is connected to the telecommunications company N = 1 the modem is disconnected and connected to the telecommunications company. N = 2 the modem is disconnected and the local phone is connected to the modem. N = 3 the modem is disconnected, the local phone is connected to the telecommunications company, and the modem is connected to the local phone. N = 4 speakers are connected to the modem, And the modem is on (play a message ). N = 5 the speaker connects to the modem, And the modem disconnects (shield the call ). N = 6 the microphone is connected to the modem, And the modem is down (recording greetings ). N = 7 connect the microphone and speaker, and the modem is detached (Sound Amplifier ). |
| + VLS =? |
Analog source/target selection and DTMF/audio report. Use at + VLS =? The Command requires the modem to report the DTMF/audio function. For each system configuration in the speech mode (Sound Amplifier and Q & A), the modem report is used to configure the enabled features. For each configuration, the modem displays tone reporting functions in the following three different voice states: voice transmission data, voice receiving data, and voice command status. |
| + ASD = <SDS>, <SDI> |
Static noise detection (silent and static noise ). At + ASD = <SDS>, <SDI> command to set the static noise detection sensitivity and the interval between <SDS> and static noise detection <SDI>. <SDS> a greater value indicates that the modem uses the noisy line conditions as mute. The default value is-40 dBm. <SDS> = 128 is the sensitivity rating. <SDS> greater than 128, the higher the sensitivity; <SDS> = 129 is-39 dBm. <SDS> lower than 128, the lower the sensitivity; <SDS> = 127 is-41 dBm. <SDI> specify the time that the modem needs to wait before reporting static noise to the computer. It is used to determine the so-called hanging (static noise), beyond which the modem sends <DLE> to the computer. The default value is 5 seconds. |
| + VSM = CRF, VSR |
Compression methods and sampling specifications. At + VSM = CRF. VSR enables the compression mode and sampling specification. In this mode, the CRF indicates the compression mode mark, and the VSR indicates the voice sampling rate. |
| + VSM? |
Returns the current compression method and sampling specification. At + VSM? Returns the number and string marker of the current compression method and the sampling rate currently in use. |
| + VSM =? |
Return the supported compression methods and sampling specifications.

Law, (8000) 132, Ima ADPCM, (8000) |
| + VRA = N |
The timer is never displayed when the system calls back. When the modem initiates a call, no timer is displayed when it uses the return Bell. This command is used to set a timer to indicate the time that the modem needs to wait before the remote modem is detached. |
| + VRN = N |
The timer is never displayed when the system calls back. When a modem sends a call, it never receives a timer when it calls back. The at + VRN command sets the timer, which indicates the time when the modem searches for the initial return Bell. If no callback is detected during this interval, the modem is deemed to have been removed from the remote modem. |
