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.
