AXB-DTMF+ DTMF+ Interface
Product Information
The AXB-DTMF+ DTMF Interface (FIG. 1) links an Axcess central controller to a telephone
network, enabling dual tone multi-frequency (DTMF) and audio pass-through control. The AXB-
DTMF+, with a programmed central controller, processes incoming calls and initiates outgoing
calls to any pager or cellular phone.
The multi-function AXB-DTMF+ can be integrated for many imaginative and creative purposes
within a home or work environment using touch-tone control. For example, the AXB-DTMF+ can
announce callers by caller ID data, or can set up an audible menu selection to process incoming
calls for routing.
The audio pass-through can be used with an AXC-SPE Enhanced Speech Synthesizer card, or PC
sound card to produce audible menus, monitor phone audio, or provide audio input such as music
on hold. The AXB-DTMF+ allows a user to issue instructions to the AMX Central controller from
a remote location using any touch-tone telephone.
The AXB-DTMF+ receives and decodes DTMF audio signaling and sends the decoded data to the
central controller for the switching/controlling of any devices connected to the central controller.
An Axcess program written on a personal computer, and downloaded to the central controller,
enables the central controller to interpret the data received from the AXB-DTMF+. The program
may also issue menu selections over the telephone through an optional AXC-SPE card. For more
information about programming a central controller, refer to the Axcess Programming Guide.

AXB-DTMF+ DTMF+ Interface
Configuration and Installation
Setting the Internal Jumpers
There are two 2-position jumpers on the AXB-DTMF+ circuit card (FIG. 1). Each jumper is set to a
default pin setting. These jumpers are positioned to enable automatic call answering and select line
setting for a leased line or phone operation.
Auto Answer mode
The 2-position jumper JP2 selects auto answer ON or OFF mode when the system powers on.
When the auto answer is on, the AXB-DTMF+ answers on the ring set by the Send_Command
COUNT-XXX. If the ring count is set to 3, for example, auto answer picks up the call after the
third ring. The default count is 1 ring. The default jumper setting is shown in FIG. 2.
To change the auto answer default from ON to OFF:
1. Remove the AXB-DTMF+ unit cover.
2. Remove the jumper from pins 2 and 3, and place it on pins 1 and 2.
3. Re-install the AXB-DTMF+ cover onto the unit housing.

Wiring the AXB-DTMF+
Preparing captive wires
To connect the wiring into a captive-wire connector:
1. Strip 1/4 inch off the wire insulation for all four wires.
2. Tin 2/3 of the exposed wire.
3. Insert each wire into the appropriate captive-wire connector up to the insulation.
4. Tighten the captive screws to secure the fit in the connector.
Wiring guidelines
The interface requires a 12 VDC power to operate properly. The interface uses a PSN2.8 power
suppl. The Central Controller supplies power via the AXlink cable or external 12 VDC power
supply. The maximum wiring distance between the Central Controller and interface is determined
by power consumption, supplied voltage, and the wire gauge used for the cable. The table below
lists wire sizes and maximum lengths allowable between the AXB-DTMF+ and Central Controller.
The maximum wiring lengths for using AXlink power are based on a minimum of 13.5 volts
available at the Central Controller’s power supply.

AXB-DTMF+ DTMF+ Interface
Connecting External Telephone Lines
Telephone cabling for both the input and extension lines are standard RJ-11 type connections.
Follow these steps to connect external telephone lines.
1. Check the circuit card jumper settings to match line type and auto answer mode. For more
information, refer to AXB-DTMF+ Jumpers in the Pre-Installation section of this manual.
2. Connect the AXlink cable to the Axcess Central controller AXlink input.
3. Connect the male RJ-11 jack of the incoming telephone line input to the AXB-DTMF+ LINE
jack and the extension telephone cable to the PHONE jack on the rear of the AXB-DTMF+.
4. Adjust the AUDIO OUT level by referring to the Audio Pass-Through Level paragraphs in this
section.
Audio In
The audio in is provided for music on hold or for voice menu selections if connected. If the audio
volume is too low or too high, the audio in level needs to be adjusted. Increase or decrease the audio
in pass-through level (gain) from the AXB-DTMF+. The AUDIO IN pot is located about mid-center
on the AXB-DTMF+ circuit board (see FIG. 1). Perform these steps to adjust the audio in level.
1. Remove the AXB-DTMF+ cover from the unit housing. Then, apply an audio signal (1 V p-p
maximum) to the AUDIO IN connector.
2. Listen on-line and use a small flat-blade screwdriver to turn the pot counter clockwise to
reduce audio level from AUDIO IN. Turn the pot clockwise to increase the AUDIO IN level.
3. Re-install the AXB-DTMF+ cover onto the unit housing.
Audio Out
The AUDIO OUT jack provides a means of routing line level signals, which originates on the
telephone line to an external device such as a sound card.
Cables and connectors for telephone and audio hook-up are not included with the
AXB-DTMF+.
If audio is connected to the AXB-DTMF+, make sure the audio is turned on by using
the correct Send_Commands. Refer to the Axcess Programming section.
To prevent "howling", make sure that the AXB-DTMF+ AUDIO IN and AUDIO OUT
lines are not looped back through an external device.

Configuration and Installation
6AXB-DTMF+ DTMF+ Interface
Testing the AXB-DTMF+
Follow these steps to test the AXB-DTMF+:
1. Disconnect AXlink power.
2. Remove the cover from the unit housing and set the AUTO ANSWER jumper to AUTO ANSWER
ON then reinstall the cover on the unit housing.
3. Reconnect AXlink power. The status LEDs should blink in sequence from right to left and the
AXlink green LED should be blinking.
4. Place a call to the AXB-DTMF+ from an outside line.
5. The RING LED should light with an incoming ring.
6. The OFF HOOK LINE LED should light after 1 ring.
7. The DTMF RX LED should light when tones are sent from the calling telephone.
8. Check line quality and operation using an extension telephone connected to the PHONE jack.
9. Return the AUTO ANSWER jumper to OFF position, if desired.
Off-hook line and off-hook phone troubleshooting
The off-hook line and off-hook phone LEDs light only if there is a good telephone line connection.
If either the off-hook line or off-hook phone LED fails to light, a faulty telephone line connection is
indicated.
Make sure a proper phone line connection exists to light both off-hook and extension off-hook
LEDs. Test the off-hook line by following these test procedures:
1. Take the AXB-DTMF+ off-hook by issuing the off-hook Send_Command from the central
controller. If there is a good telephone line connection, then the OFF HOOK LINE LED lights.
2. If the OFF HOOK LINE LED fails to light, then there is a bad or faulty telephone line
connection. Check the incoming telephone line and make sure it is working properly. Then,
check the RJ-11 cable and its connection to the AXB-DTMF+.
Test the off-hook phone using the following steps:
1. Take the receiver off the extension telephone. If there is a good telephone line connection, then
the EXTENSION OFF HOOK LED lights.
2. If the OFF HOOK PHONE LED fails to activate, make sure that an extension off-hook
Send_Command has not been issued (you can do a Send_Command extension on-hook to be
sure; see the Operative Send_Commands section on page 7 for details). If this does not
produce results, then there is a faulty telephone line connection. Check the incoming telephone
line and make sure it is working properly. Then, check the RJ-11 cable and its connection to
the AXB-DTMF+. Make sure the RJ-11 cable from the extension telephone is good.
The extension telephone is optional and supplied by the user.

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.
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
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.

Distinctive Ring Patterns and Send_Commands
Distinctive ringing is a service provided by the local telephone company. Distinctive ring allows
additional phone numbers to be assigned to a single phone line. Then, depending upon the number
dialed, the ringing pattern is different.
The AXB-DTMF+ can identify up to four distinctive ring default patterns. Default time values for
each pattern are shown in FIG. 1. A pattern consists of five parts. Depending on the ring pattern, a
part is either high or low. The distinctive ring patterns shown illustrate the envelope of the incoming
ring with respect to time. The four default patterns are:
! Default Pattern 1: 1 long ring lasting 2 seconds followed by 4 seconds of silence.
! Default Pattern 2: 2 rings, in a 2 second period, followed by 4 seconds of silence.
! Default Pattern 3: 2 short rings and 1 long ring, in a 2 second period, followed by 4
seconds of silence.
! Default Pattern 4: 1 short, 1 long, and 1 short ring, within a 2 second period, followed
by 4 seconds of silence.

Time values are in milliseconds (1000 ms equals 1 second). All 4 distinctive ring
patterns are within a 2-second period from start to end time, for most applications. If
you plan to change any of the distinctive ring patterns, it is advisable to stay within a 2
second time frame for each distinctive ring pattern.

Changing a Default Ring Pattern
Change a default ring pattern using the appropriate Send_Command when programming the AXB-
DTMF+. Each ring pattern consists of five parts with each part having a specific Send_Command.
For more information on distinctive ring Send_Commands, refer to Distinctive Ring
Send_Commands.
Example:
Pattern 4's five parts are as follows:
! Part 1 is high and 300 ms (.3 seconds) long (ring).
! Part 2 is low and 200 ms (.2 seconds) long (no ring).
! Part 3 is high and 1000 ms (1 seconds) long (ring).
! Part 4 is low and 200 ms (.2 seconds) long ( no ring).
! Part 5 is high and 300 ms (.3 seconds) long (ring).
If you want to change the time values of Parts 2 and 4 (no ring) of Pattern 3:
1. To change Part 2 of Pattern 3, use the Send_Command 'P3_2-XXX' where:
! Time increment = 10 ms
! Default at reset = 20 (20 x 10 ms = 200 ms)
For example, issue the Send_Command
SEND_COMMAND DTMF, 'P3_2-25 ' (25 x 10 ms = 250 ms)
to change Part 2 of Pattern 3 from a value of 200 ms (.2 seconds) to 250 ms (.250
seconds).
2. To change Part 4 of Pattern 3, use the Send_Command 'P3_4-XXX' where:
! Time increment = 10 ms
! Default at reset = 20 (20 x 10ms = 200ms)
For example, issue the Send_Command
SEND_COMMAND DTMF, 'P3_4-25 ' (25 x 10ms = 250ms)
to change Part 4 of Pattern 3 from a value of 200 ms to (.2 seconds) to 250 ms (.250
seconds).
3. The normal length of time from the start of any pattern to its end time is usually 2- seconds. If
you increase the time value for any part of a pattern, make sure to decrease another part by the
same amount, maintaining the 2- seconds overall time for the pattern. For example, if you
increased the value of Parts 2 and 4 of Pattern 3 by 5 ms each, decrease Part 3 by 10 ms.
Values specified are in increments of 10 ms. That is, a value of 1 yields 10 ms, while
a value of 100 yields 100 x 10 ms, or 1 second.
