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

			Chapter 5 – AT Commands, S-Registers, and Result Codes
Command:	+PQC=n	Quick Connect Control
Values:	n = 0, 1, 2, or 3
Default:	3
Description:	Controls the V.92 shortened Phase 1 and Phase 2 startup procedures (Quick Connect).
	When line conditions are stable, quick connect results in shortened connect times; however,
	significant fluctuation in line conditions from call to call can result in longer connect times, in
	which case it may be advisable to disable quick connect.
	+PQC=0		Enables Short Phase 1 and Short Phase 2 (Quick Connect)
	+PQC=1		Enables Short Phase 1
	+PQC=2		Enables Short Phase 2
	+PQC=3		Disables Short Phase 1 and Short Phase 2
	+PQC=?		Displays the allowed values
	+PQC?		Displays the current value
Command:	+VCID=n	Caller ID Selection
Values:	n = 0, 1, or 2
Default:	0
Description:	Enables Caller ID detection and configures the reporting and presentation of the Caller ID
	data that is detected after the first ring. The reported data includes the date and time of the
	call, the caller's name and number, and a message. Set S0=2.
	+VCID=0		Disables Caller ID
	+VCID=1		Enables Caller ID with formatted data
	+VCID=2		Enables Caller ID with unformatted data
	+VCID=?		Displays the allowed values
	+VCID?		Displays the currrent value
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 currrent value.
Command:	#CBAn	Callback Attempts
Values:		n = 1–255
