Voice Commands for the MT5656ZDXV and MT5600ZDXV Modems

Multi-Tech Systems, Inc. Commands Reference Guide (PN S000273D)

AT+VSM=129, 7200, 0, 0 The PC changes its PC/modem interface rate to 38400 bps and selects a

compression method with the least sensitive setting, with the goal of

playing a message with less distortion, and at 7200 samples per second.

(Assume that the PC issued a +VSM=? command earlier.)

OK The modem agrees.

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 Tranmit mode.

CONNECT The modem agrees.

<Data> The PC deleivers <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.

Command Response

AT+FCLASS=8; The DCE switches to Voice mode. The DTE selects a fixed DTE-DCE interface

AT+VIT=60; rate. The DTE knows from the sample rate selected earlier and the bits-per-

+VPR=16 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

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).
