Technics MT5634SMI-34, MT5634SMI-92 manual AT Commands, S-Registers, and Result Codes

			Chapter 5 – AT Commands, S-Registers, and Result Codes
Command:	+VDR=x, y		Distinctive Ring Report
Values:		x = 0, 1 Distinctive Ring report control. See description.
		y = 0–255	Minimum ring interval in 100 ms units. See description.
Default:		0, 0
Description:		Enables reporting of ring cadence information to the DTE and specifies the minimum ring
		cadence that will be reported.
		The 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 100 ms<CR><LF>, and the length
		of the ring is in the form DRON=number in units of 100 ms<CR> <LF>. The modem may
		produce a Ring event code after the DRON message if enabled by the y parameter. The y
		parameter must be set to a value equal to or smaller than the expected ring cadence in
		order to pass the report to the DTE.
		+VDR=0, n/a Disables Distinctive Ring cadence reporting.
		+VDR=1, 0	Enables Distinctive Ring cadence reporting. Other call progress result codes
			(including RING) are reported as normal.
		+VDR=1, >0 Enables Distinctive Ring cadence reporting. The RING result code is
			reported after the falling edge of the ring pulse (i.e., after the DRON report).
		+VDR=?	Displays the allowed values.
		+VDR?	Displays the current value.
Command:	#CBAn	Callback Attempts
Values:		n = 1–255
Default:		4
Description:		Sets the number of callback attempts that are allowed after passwords have been
		exchanged between modems.
Command:	#CBDn	Callback Delay
Values:		n = 0–255
Default:		15
Description:		Sets the length of time (in seconds) that the modem waits before calling back the remote
		modem.
Command:	#CBF?	Callback Failed Attempts Display
Values:		n/a
Default:		n/a
Description:		Requests the number of failed callback passwords since reset or power-up. This number
		can be stored to nonvolatile memory using the &W command.
Command:	#CBFR	Callback Failed Attempts Reset
Values:		n/a
Default:		n/a
Description:		Resets the number of failed callback passwords to 0. This does not reset the number stored
		in nonvolatile memory.
Command:	#CBIn	Local Callback Inactivity Timer
Values:		n = 1–255
Default:		20
Description:		Sets the time (in minutes) that the modem waits for a command before forcing the user to
		enter the setup password again.
Command:	#CBNy=x Store Callback Password
Values:		y = 0–29
		x = password
Defaults:		None
Description:		Sets the callback security password for the y memory location. The password must have 6
		to 10 characters, and cannot include the + or - characters.
Command:	#CBPn	Callback Parity
Values:		n = 0, 1, or 2
Default:		0
Description:		Sets parity for the callback security messages.
		#CBP0	No parity.
		#CBP1	Odd parity.
		#CBP2	Even parity.
