IS-101 Voice Mode AT Commands

Table 25. Voice Mode Command Descriptions (Continued)

Command	Default			Description

		Distinctive Ring Selection: This command contains two parameters. The first selects whether the
		modem reports distinctive ring cadence information. The second parameter controls the timing of the
		RING event code report.
		m=<enable>, <report>
		Defaults = 0, 0
		<enable> Ring Reporting: The DCE reports the length of the ring period.
		Range: <enable> = 0–255 (enables/disables distinctive ring reporting in the form DROF=<number in
		units of 0.1 seconds><CR><LF>)
		<report> Time Ring Reporting: The DCE reports the silence period’s length. The DCE may produce
		a RING event code after the DRON message if enabled by the <report> parameter. The <report>
+VDR=m	see ‘m’	parameter should be set to a value larger than the expected off-times within a single pattern so the
		RING even reports are issued only during the off-times between the complex patterns.
		Range: <report> = 0–255 (reporting type in the form DROF=<number in
		units of 0.1 seconds>)
		<enable> <report>		Function
		0	–	Distinctive ring disabled
		1	0	The modem reports DROF and DRON messages but does not report RING
		1	0	messages
				messages
		1	non-0	The modem reports DROF, DRON and RING messages
		2–255	–	Reserved
		Regardless of its setting, the +VDR command can be disabled by the +VEM command.

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