AMX AXB-DTMF+ instruction manual Channel Codes, Operation Channel # Description on Indicates

Programming

Channel Codes

Channel codes on the AXB-DTMF+ are stored in memory (firmware) and process all outbound or inbound DTMF from a set of program instructions downloaded to the Axcess Central controller.

Channel Codes

Operation	Channel #	Description (ON Indicates)
DTMF Tones	1-16	Outbound tones are produced by the AXB-DTMF+ by
		Send_Commands received from the Axcess Central controller to
		dial a phone number or send a sequence of DTMF codes over the
		phone line.
		Tones are also generated directly by activating the device channel
		corresponding to the tone. A tone is played as long as a channel is
		on. Only one tone may be active at a time. If a second channel is
		activated while another is on, this causes the first tone to stop and
		the second tone to play.
		The following channels generate DTMF code:
		• Channel 1 = 1			• Channel 9 = 9
		• Channel 2 = 2			• Channel 10 = 0
		• Channel 3 = 3			• Channel 11 = *
		• Channel 4 = 4			• Channel 12 = #
		• Channel 5 = 5			• Channel 13 = A
		• Channel 6 = 6			• Channel 14 = B
		• Channel 7 = 7			• Channel 15 = C
		• Channel 8 = 8			• Channel 16 = D
Detection	17-32	Detects DTMF "in" from an extension or phone.
		Refers to any inbound			DTMF transmitted (forwarded) to the
		Axcess AXC-EM Enhanced Master Card by the AXB-DTMF+, as
		generated by any external touch-tone phone.
		The following DTMF codes are reported to the Axcess AXC-EM
		Enhanced Master Card on the push and release of a touch-tone
		telephone button.
		• Channel 17	=	1	• Channel 25	=	9
		• Channel 18	=	2	• Channel 26	=	0
		• Channel 19	=	3	• Channel 27	=	*
		• Channel 20	=	4	• Channel 28	=	#
		• Channel 21	=	5	• Channel 29	=	A
		• Channel 22	=	6	• Channel 30	=	B
		• Channel 23	=	7	• Channel 31	=	C
		• Channel 24	=	8	• Channel 32	=	D
	34	Indicates outgoing busy signal.
		Call Progress Reporting returned to the Axcess AXC-EM when a
		busy signal is detected. During Call Progress Reporting, the sys-
		tem is responsible for any subsequent action following a progress
		indication.
	35	Indicates outgoing ring signal.
		Call Progress Reporting returned to the Axcess AXC-EM when a
		ring signal is detected.
	36	Indicates incoming ring signal (each burst indicated).
	37	Indicates AXB-DTMF+ is off-hook.
	38	Indicates extension phone is off-hook.
