Chapter 6 – Voice Commands

Command:

+VRX

Enter Voice Receive State

Values:

0, 1, 2–127, 128–255

Result Codes:

Values (above) if the modem accepts the command; ERROR if the modem is not connected to an

 

off-hook Telco line, or one non-Telco input device.

Description:

The +VRX command causes the modem to start the voice reception process. The modem starts

 

the process by returning the CONNECT result code to the PC. The modem then sends shielded

 

voice data to the PC, in the format previously selected by the +VSM command.

 

The modem exits the voice/receive state by one of two means: a <DLE><I>, and an Inactivity Timer

 

timeout. During the voice receive, the modem informs the PC of pertinent events, such as

 

Presumed End of Message (Quiet), and Presumed Hang Up (Silence) detected, Busy detected,

 

and Dial Tone detected, so that at the discretion of the PC, the PC may terminate the voice receive

 

state. On termination of the voice receive state, the modem returns the OK result code, and then

 

returns to the Voice Command state.

 

The Inactivity Timer is in effect during the receive operation. If the PC uses this timer and stops the

 

modem from performing unwanted restarts, the PC must assure that there is data sent from the PC

 

to the modem often enough to refresh the timer. The +VRX commands are as follows.

 

+VRX=0

Voice receive operation. This selection does not provide for modem periodical

 

 

tone production during a voice receive operation. The PC must issue the proper

 

 

notifications of a record operation in progress by message playbacks to satisfy

 

 

possible legal requirements.

 

+VRX=1

Voice receive operation. This selection does not provide for modem periodical

 

 

tone production during a voice-receive operation. The tone frequency and

 

 

cadence is manufacturer specific.

 

+VRX=2–127

Reserved for future specification.

 

+VRX=128–255

Manufacturer specific.

 

The result code values (0, 1, 2–127, 128–255) are returned if the modem accepts the command.

 

The ERROR result code is returned if the modem is not connected to an off-hook Telco line, or one

 

non-Telco input device.

Command:

+VTS=<string>

Produce DTMF and Tone Generation in Voice Mode

Values:

Refer to the IS-101 Spec.

Default:

Refer to the IS-101 Spec.

Result Codes:

Refer to the IS-101 Spec.

Description:

The +VTS command causes the modem to produce DTMF tones, single-frequency tones, and

 

optionally, double-frequency tones. This command allows the PC to generate a dial tone, busy, etc.

 

for those modems capable of generating two arbitrary tones. The modem may perform tone

 

detection during the playing of tones. When the modem receives the signal <DLE><!> to abort

playing of the tones, the result code OK is displayed, and the modem returns to the voice command state.

The Inactivity Timer is in effect during the receive operation. If the PC uses this timer and stops the modem from performing unwanted restarts, the PC must assure that there is data sent from the PC to the modem often enough to refresh the timer.

Modem support for the second tone generation is optional. The modem produces compliant DTMF tones when processing DTMF tone production codes.

The tone generation string consists of elements in a list where each element is separated by commas. Each element can be:

1.A single ASCII character in the set of 0–9, #, *, and A–D

2.

A string enclosed in square brackets [ ] , or

3.

A string enclosed in curly braces { }

The modem interprets item 1 as a DTMF digit with duration set by the +VTD command. The modem interprets item 2 as a general dual tone and duration selection. The modem interprets item 3 as a DTMF tone with a different duration than that given by the +VTD command.

Missing parameters are assumed to be the default value. Unspecified values always default to 0 for frequencies, DTMF * for DTMF tones, and +VTD for duration. The omission of commas (and associated subparameters) is valid.

The quantity in the square brackets consists of a three-element list. The first element is the first frequency, the second element is the second frequency, and the third element is the duration, in 0.01second intervals. A list may contain null elements. For example, [3000] means that the modem generates a single tone at 3000 Hz for the default duration. [3000,3300] means that the modem
