+
{{I}}
−
The AlphaCom system is prepared for distribution of '''audio programs'''. There must be an external audio source as input to each program, a radio, CD-player, alarm device or other sound input.
+
The ICX-AlphaCom system supports distribution of '''Audio Programs'''. This feature is typically used for distribution of background music. Up to 70 Audio Program channels are supported.  
  
−
A number of inputs for audio programs are available, depending on the system configuration. By default 6 audio program inputs are available via the [[APC|APC board]] for the [[AlphaCom XE20]] and [[AlphaCom XE26]], and 2 audio program inputs via [[ASLT|ASLT board]] in position 1 for the [[AlphaCom XE7]]. The number of audio program inputs can be expanded to 70 (36 in XE7) by using [[AGA#Multi_Program_Distribution|AGA board]]. Audio program input by IP-Stations is not supported yet (AMC 11.5.3.2B).
+
Audio source can be:
 +
* An analog audio source, typically a radio, CD-player, alarm device connected to the [[TKIE-2|TKIE-2 kit]]. The TKIE-2 kit is used as an interface between the analog audio source and the ICX-AlphaCom server. (See image to the right).
 +
* An audio stream from a PC (e.g. a local audio file or stream from an internet radio) directly to the ICX-AlphaCom server. One can use the application ffmpeg on the PC to generate the stream.

For Audio Program distribution in the previous generation servers AlphaCom XE, see [[Audio Program (AlphaCom XE)|here]].
−
To listen to an audio program, dial the program number (default 801 - 806). The audio program is switched off by pressing the C-key or by dialing 800.
 
  
−
When lifting the handset the dialing tone is normally heard, replacing any program. To listen to the program with the handset off, simply hold the M-key down while lifting the receiver, and the dialing tone is not turned on.
+
== Using analog source and TKIE kit ==
 +
When using the [[TKIE-2|TKIE-2 kit]], the analog audio signal is connected to the [[Turbine_Extended_series_board_connectors|Auxiliary connector pin 8 and 9]] of the TKIE kit. One TKIE kit is required for each Audio Program channel.

== Audio Programs in XE7 ==
 
−
By default it is possible to connect 2 audio programs (805 & 806) to AlphaCom XE7. These must be connected to physical position 5 & 6, and an ASLT board must be present in board position 1.
 
−
The number of Audio Programs can be extended by adding AGA boards. Each added AGA board provides 6 Audio inputs for program distribution. The AGA boards can be placed in any board position.

Icx icon.png

The ICX-AlphaCom system supports distribution of Audio Programs. This feature is typically used for distribution of background music. Up to 70 Audio Program channels are supported.

Audio source can be:

  • An analog audio source, typically a radio, CD-player, alarm device connected to the TKIE-2 kit. The TKIE-2 kit is used as an interface between the analog audio source and the ICX-AlphaCom server. (See image to the right).
  • An audio stream from a PC (e.g. a local audio file or stream from an internet radio) directly to the ICX-AlphaCom server. One can use the application ffmpeg on the PC to generate the stream.

For Audio Program distribution in the previous generation servers AlphaCom XE, see here.

Using analog source and TKIE kit

When using the TKIE-2 kit, the analog audio signal is connected to the Auxiliary connector pin 8 and 9 of the TKIE kit. One TKIE kit is required for each Audio Program channel.

Audio Program distribution, using the TKIE kit as analog interface

First configure the TKIE kit to register to the ICX-AlphaCom.

In AlphaPro Users & Stations, select the TKIE and set the Class of Service = SuperUser, and disable Noise Reduction:

For the TKIE set the Class of Service = SuperUser, and disable Noise Reduction


In AlphaPro Users & Stations, select the TKIE and select the button "Events". Insert an event 13, when change to OFF with action: $DD L%1.dir L6801. This event is triggered when the TKIE comes up after a reset of TKIE or a reset of the server.


Event Handler: TKIE-2 dials 6801 after startup



In AlphaPro Directory & Features, scroll to the bottom of the directory list and check if directory number 6801 with feature number 118 already exists.

If not, press Insert and create a new directory number with feature 118 - Program Source. Set ID = 1 (this specifies the program channel 1).

The example below shows how to add directory number 6801 with feature number 118.

A device dialing 6801 will become the source for Audio Program 1 (ID = Program channel)



If multiple Audio Program channels are to be added, one must add 6802 - feature 118 and ID = 2, 6803 - feature 118 and ID = 3, etc.


Log in to the web interface of the TKIE. Verify that audio from line in is enabled, and that AGC is disabled:

Line In enabled and AGC off


Finally, one have to reboot either the TKIE kit or the ICX-AlphaCom for all settings to take effect.

Now you should be able to listen to Audio Program channel 1 by dialing 801 on an intercom station.

For remote setup and other Audio Program related functions, see Audio Program features.

Audio Program distribution, streaming from a PC using ffmpeg

Streaming audio from a PC

Configure the IP Dummy Station

The PC is streaming audio to an IP Dummy station using the ffmpeg program. The IP Dummy Station is configured as the "Source" for an Audio Program channel. One IP Dummy Station is required for each Audio Program channel.

OBS icon The IP Dummy Station requires an IP Station License


In AlphaPro Users & Stations, "General" tab, select a free user and configure as described below (Directory Number and Display Text are just examples):

Set the Class of Service = SuperUser


In AlphaPro Users & Stations, "Station Type" tab, enable the "IP Dummy Station" flag:

Set the "IP Dummy Station" flag



In AlphaPro Users & Stations select the IP Dummy and select the button "Events". Insert an event 13, when change to OFF. This event is triggered when the ICX-AlphaCom starts up.

Event Handler: IP Dummy dials 6801 after startup


Action: 

$VAC L%1.dir U8 '10.9.8.189' W4002 W4004
$DD L%1.dir L6801


The first line will define UDP port 4004 as the receiving port for the Audio Stream. (Port 4002 is defined as the sending port, but is not used in this case):

  • U8 = Use G.722 codec
  • 10.9.8.189 = The IP Address of the PC
  • 4004 = UDP port for receiving audio

The second line tells the IP Dummy to dial 6801, and by that become the source for Audio Program 1.


In AlphaPro Directory & Features, scroll to the bottom of the directory list and check if directory number 6801 with feature number 118 already exists.

If not, press Insert and create a new directory number with feature 118 - Program Source. Set ID = 1 (this specifies the program channel 1).

The example below shows how to add directory number 6801 with feature number 118.

A device dialing 6801 will become the source for Audio Program 1 (ID = Program channel)


If multiple Audio Program channels are to be added, one have to use multiple IP Dummy Stations, and create 6802 - feature 118 and ID = 2, 6803 - feature 118 and ID = 3, etc.

Filters settings

The UDP ports used for audio streaming must be added and applied to the ICX-AlphaCom firewall; Filters

Define and Open the relevant UDP ports in the ICX-AlphaCom Filter settings. Here: UDP ports 4002 - 4004.


Finally, one have to reboot the ICX-AlphaCom for all settings to take effect.

PC setup

ffmpeg.exe -re -i "C:\Programmer\ffmpeg\media\06 Paradise by the Dashboard Light.mp3" -ac 1 -acodec g722 -ar 16000 -filter:a volume=-6dB -f rtp rtp://10.9.8.20:4004


  • "C:\Programmer\ffmpeg\media\06 Paradise by the Dashboard Light.mp3" = audio source. This could be e.g. the url of an internet radio.
  • 10.9.8.20 = IP Address of the ICX-AlphaCom
  • 4004 = The UDP port used by the IP Dummy Station
  • -filter:a volume=-6dB = Sets the volume

Now you should be able to listen to Audio Program channel 1 by dialing 801 on an intercom station.

Audio Program features

Audio Program selection

To listen to an audio program, dial the program number (default 801 - 806). The audio program is switched off by pressing the C-key or by dialing 800.

When lifting the handset the dialing tone is normally heard, replacing any program. To listen to the program with the handset off, simply hold the M-key down while lifting the receiver, and the dialing tone is not turned on.

Active audio programs are automatically restored after server reset.

Audio Program Step

You can step through a list of available programs by dialing 790 on your station. Program off (800) is always included in the list. There are two alternative program step sequences.

The sequences after autoload


  • The number of programs in each sequence is programmable from AlphaPro, Audio Programs > General Settings. This sequence setting is valid for the entire system.
  • Each station can choose between sequence 1 or 2. By default all stations are assigned to sequence 1, this can be changed in Users & Stations → User Preferences.

Program step codes:

Audio Program Priority

  • During conversation the audio program is by default temporarily disconnected. This can be changed per audio program by the flag "Program over Conversation" in the Audio Program menu in AlphaPro. When the flag is set, the audio from the audio program will be mixed with the audio from the conversation.
AudioProgram DuringConversation.png


  • During group calls the audio program and the group call audio is by default mixed. This can be controlled from AlphaPro by the flag "Mute Program During Group Call" in Exchange & System → System → Calls and Options. When the flag is set the audio program is temporarily disconnected during the group call. This is a global flag which applies to the whole system.
AudioProgram MuteDuringGroupCalls.png


  • Each audio program channel has a "Volume/Handset override" flag, located in the Audio Program menu in AlphaPro. When set the Volume & handset override feature is activated for display stations if the program is activated by remote set-up to Group. This can be used when distributing alarm messages via the audio program channel.
AudioProgram VolumeHandsetOverride.PNG


Remote set-up of Audio Program

Audio Program can remotely be turned on from a station:

  • Audio program to another station: 74 + subscriber number + program number. E.g. 74 + 101 + 805
  • Audio program to a group (SuperUser only): 75 + group number + program number. E.g. 75 + 86 + 805

Use code 800 to turn the audio program off.


Audio Program can also be set up from RCI or Event Handler using the following commands:

  • PRS - Program to Station
  • PRG - Program to Group
  • $PROG - Program to station or group

Other audio program related commands and macros:

  • $TPROG - Temporarily turn ON/OFF program distribution to a station
  • %prog - Read active program

Events related to Audio Program
