AMX AXB-DTMF+ instruction manual Fine Tuning SendCommands

Programming

Timing System Send_Commands (Cont.)

Command	Description
TONE TIME-XXX	Set length of each generated tone and time between tones in the Dial
	Send_Command (refer to 'DIAL-X-XXX-XXXX')
	• Time increment = 1 ms
	• Default at reset = 100 ms
	Example:
	SEND_COMMAND DTMF, 'TONE TIME-100'
	Sets tone time length to .11 second (110 ms).

Fine Tuning Send_Commands

The following table lists the commands that fine tune AXB-DTMF+ signal timing. Most likely, you will not have to change Fine Tuning parameters.The commands are listed alphabetically by operation and include syntax, syntax descriptions, usage examples, time increments, and reset default values.

Fine Tuning Send_Commands

Command	Description
CPGAIN-OFF	When off does not add gain (in addition to IGAIN) to dial tone call progress sig-
	nal.
	Default at reset = YES
	Example:
	SEND_COMMAND DTMF, 'CPGAIN-OFF'
	Sets gain into call progress detector chip as default.
CPGAIN-ON	When on adds gain (in addition to IGAIN) to dial tone call progress signal.
	Default at reset = NO
	Example:
	SEND_COMMAND DTMF, 'CPGAIN-ON'
	Sets gain into call progress detector chip as default.
IGAIN-OFF	Controls gain of "internal signals" on the AXB-DTMF+. The internal signals are
	call progress tones such as incoming DTMF, receiver off-hook, and called num-
	ber is busy. Setting gain to "off" causes it to return to default level.
	Default at reset = YES
	Example:
	SEND_COMMAND DTMF, 'IGAIN-OFF'
	Sets internal gain on AXB-DTMF+ to default.
IGAIN-ON	Controls gain of "internal signals" on AXB-DTMF+. The internal signals are call
	progress tones such as incoming DTMF, receiver off-hook, and called number
	is busy. Setting gain to "on" increases gain above default level. This may be
	helpful if signals are not being detected due to attenuation over the phone line.
	Default at reset = NO
	Example:
	SEND_COMMAND DTMF, 'IGAIN-ON'
	Sets internal gain on the AXB-DTMF+ to high.
