+VDR
Description:
Syntax:
Values:
Beep Tone Duration Timer (DTMF/Tone Generation Duration)
Sets the default DTMF/tone generation duration used with the +VTS command. This
command does not affect the ATD command settings. The <dur> parameter range is
given by the +VTD=? command, in units of 0.01 seconds. A setting of +VTD=0
specifies a manufacturer-specific time interval.
AT+VTD=<dur> .
<dur> A decimal number specifying the default DTMF/tone generation duration in
units of 0.01 seconds.
A value of 0 specifies the value entered by the S11 parameter (50 to 255
ms). the range is 0.01 to 2.55 seconds for <dur> 1 to 255. Default = 100.
OK if <dur> = 0-255.
ERROR if the parameter is out of range or if not in Voice mode.
+VTD? Displays current or selected values.
+VTD=? Displays a list of the supported values.
Distinctive Ring (Ring Cadence Reporting)
Enables or disables reporting of the ring cadence information and controls the timing
of the Ring event code report if ring cadence reporting is enabled.
This report format is one line per silence period, and one line per ring period. The
length of the silence period is in the form DROF=<number in units of 0.1
seconds><CR><LF>, and the length of the ring in the form DRON=<number in units
of 0.1 seconds>. The <LR> character is optional. The modem may produce a Ring
event code after the DRON message if enabled by the <report> parameter. The
<report> parameter should be set to a value larger than the expected off-times within
a single pattern so that the Ring event reports are issued only during the off-times
between the complex patterns.
AT+VDR=<enable>,<report>
<enable> A decimal number corresponding to the selected option:
0 The modem will not generate ring cadence reports. Other call
progress event codes (including Ring) are reported as normal.
1 The modem will report ring cadence information as specified for the
<report> subparameter. Default.
<report> A decimal number specifying ring cadence information report when
enabled by the <enable> subparameter.
0 The modem will produce only DROF and DRON messages. The
modem will not produce a RING event codes. The modem will
report other call progress event codes as normal.
Other The modem will produce only DROF and DRON messages.
The modem will produce a RING event code after <report>/10
seconds after the falling edge of the ring pulse (i.e., after the
DRON report).. The modem will report other call progress
event codes as normal.
Example: The lines below shows a cadence with an off time of 4.0 seconds, an on
time of 0.8 seconds, an off time of 0.4 seconds, and an on time of 0.8 seconds. The
RING result code is displayed 0.5 seconds after the last DRON message. The
command to enable this sample sequence is +VDR-1,5 , as shown below:
<DLE><X>
DROF=40
DRON=8
DROF=4
DRON=8
RING
<DLE><.>
<DLE><X>
DROF=40
