Programming
22 AXB-DTMF+ DTMF+ Interface
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 2 = 2
• Channel 3 = 3
• Channel 4 = 4
• Channel 5 = 5
• Channel 6 = 6
• Channel 7 = 7
• Channel 8 = 8
• Channel 9 = 9
• Channel 10 = 0
• Channel 11 = *
• Channel 12 = #
• Channel 13 = A
• Channel 14 = B
• Channel 15 = C
• 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 18 = 2
• Channel 19 = 3
• Channel 20 = 4
• Channel 21 = 5
• Channel 22 = 6
• Channel 23 = 7
• Channel 24 = 8
• Channel 25 = 9
• Channel 26 = 0
• Channel 27 = *
• Channel 28 = #
• Channel 29 = A
• Channel 30 = B
• Channel 31 = C
• 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.
