Chapter 6 – Voice Commands

AT+VLS=4

The modem selects the speaker. The modem had earlier reported that a speaker was

 

available.

OK

The modem agrees.

AT+VTX

The PC selects the Voice Transmit mode.

CONNECT

The modem agrees.

<Data>

The PC delivers <DLE> shielded and silence compressed voice data across the

 

PC/modem interface.

<DLE> <ETX>

The PC indicates the end of the Voice data stream.

OK

The modem indicates it is in Voice Command mode.

AT+VLS=0

The PC deselects all devices.

OK

The modem agrees.

 

The PC switches to Data mode, Command mode, and autobauding enabled:

 

AT+VIT=0; +VPR=0; +FCLASS=0

OK

The modem agrees.

Answer Phone, Play Greeting Message, and Record Message Example

Command

Response

AT+FCLASS=8;

The DCE switches to Voice mode. The DTE selects a fixed

AT+VIT=60;

DTE-DCE interface rate. The DTE knows from the sample

+VPR=16

rate selected earlier and the bits-per-sample that the DTE-DCE interface rate should be

 

38400 bps. The DTE-DCE Inactivity Timer starts with 60 seconds.

OK

DCE agrees (to the old DTE/DCE interface rate).

AT+VSM=129, 7200, 0, 0 DTE changes its DTE/DCE rate to 38400 bps and selects a compression method with the least sensitive setting, with the goal of recording a message with less distortion, and at 7200 samples per second. Assume that the DTE issued a +VSM=? command earlier.

OK

The DCE agrees.

AT+VSD=127, 20

DTE selects a silence detection period of 2 seconds.

AT+VLS=0

DTE selects a silence detection period of 2 seconds with the least sensitive setting (for

 

detecting the end of voice recording).

OK

The DCE agrees.

AT+VIT=0;

The DTE selects the Data mode with autobauding, and disables +VPR=0; automatic DCE

 

answering. The DCE waits for a phone call.

+FCLASS=0

(not necessarily in Data mode).

S0=0

 

OK

The DCE agrees.

RING

At some time, a remote station calls.

AT+FCLASS=8;

The DCE switches to Voice mode. The DCE selects a fixed AT+VIT=60; DTE/DCE

 

Interface Rate. The DTE knows from the sample AT+VPR=16; rate selected earlier and

 

the bits per sample that the DTE/DCE Interface Rate should be 38400 baud. The

 

DTE/DCE Inactivity Timer starts with a value of 60 seconds.

OK

The DCE agrees (at the old DTE/DCE Interface Rate).

AT+VLS=0

The DTE selects all devices.

OK

The DCE agrees.

AT+VIT=0;

The DTE selects Data mode/Command mode with

+VPR=0;

autobauding, and disables automatic DCE answering. The +FCLASS=0; DCE waits for a

S0=0

phone call (not necessarily in Data mode).

 

AT+FCLASS=8;

The DCE switches to Voice mode. The DCE selects a fixed DTE/DCEAT+VIT=60;

AT+VPR=16;

Interface Rate. The DTE knows from the sample rate selected earlier and the bits per

 

sample that the DTE/DCE Interface Rate should be 38400 baud. The DTE/DCE Inactivity

 

Timer starts with a value of 60 seconds.

OK

The DCE agrees (at the old DTE/DCE Interface Rate).

<DLE> <R>

The DCE selects another ring (at 38400 bps).
