IS-101 Voice Mode AT Commands

Table 25. Voice Mode Command Descriptions (Continued)

Command Default

Description

DTMF and Tone Generation: This command causes the modem to generate DTMF tones or pulse tones in voice mode. The <DLE><!> code aborts the playback of tones, sends the ‘OK’ result code, and returns the modem to the voice command state. The DTE/DCE inactivity timer is in place during tone production. The command +VTS sent without a parameter assumes the default value, which is a null string. The DTE may use the <DLE><NUL>-shielded code to refresh the timer.

m=<string> The <string> is made up of a list of <freq> and <duration> parameters. <freq> is in units of Hz, and <duration> is in units of 0.01 seconds.

The tone string consists of up to three types of elements: a single ASCII character, a string in brackets, and a string in braces. Commas must separate the elements. Missing elements assume the value of zero. The following list explains each element and how it can be used.

1.Single ASCII character in the set, 0–9, #, *, ! and A-D, which is interpreted as a single DTMF tone. DTMF tones are sent as a single element expressed in the form:

AT+VTS=<DTMF or !>

For example, to send a DTMF 1 tone, issue AT+VTS=1 to the modem.

2.String drawn from the first set but not including a flash hook code ‘!’ and enclosed in brackets “[ ]”,which can produce a single or dual tone. The string includes three parameters, which set the frequency of two non-standard DTMF or single tones and a common duration for both. The quantity in brackets consists of a three-element list that is expressed in the following format:

AT+VTS=[<first tone freq 1>, <second tone freq 2>, <duration>]

If the duration is not specified in the <duration> parameter, the modem sends tones for the duration specified by the +VTD=m command.

a. Single tones can be sent in brackets using the following format:

+VTS=m

none

AT+VTS=[<first tone freq 1>]

 

 

or

 

 

AT+VTS=[<first tone freq 1>, <space>, <duration>]

 

 

For example: AT+VTS=[3000] This sends a single tone of 3000 Hz with a default duration

 

 

specified by +VTD=m.

 

 

For example: AT+VTS=[3000,,50]

 

 

This sends a single tone of 3000 Hz with a duration of 500 ms (50 x 0.01 second).

 

 

b. Dual tones may be sent using the following format:

 

 

AT+VTS=[<first tone freq 1>,<second tone freq 2>]

 

 

or

 

 

AT+VTS=[<first tone freq 1>,<second tone freq 2>,

 

 

<duration>]

 

 

For example: AT+VTS=[3000,3300]

 

 

This sends a dual tone of 3000 Hz and 3300 Hz with the default duration set by the +VTD=m

 

 

command.

 

 

For example: AT+VTS=[3000,3300,50]

 

 

This sends a dual tone of 3000 Hz and 3300 Hz with a duration of 500 ms (50 x 0.01 second).

 

 

c. This command can be used to send a period of silence in a tone string. Use the following format:

 

 

AT+VTS=[ , ,<duration>]

 

 

AT+VTS=[ ]

 

 

For example: AT+VTS=[ , ,50]

 

 

This sends a 500 ms period of silence.

NOTE: An asterisk (*) denotes the factory-default setting.
