Audio Program (ICX-AlphaCom)

Audio Program distribution

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.

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 board for the AlphaCom XE20 and AlphaCom XE26, and 2 audio program inputs via ASLT board in position 1 for the AlphaCom XE7. The number of audio program inputs can be expanded by using AGA board. From AMC10.50 the maximum number of program feeds is increased to 70. Audio program input by IP-Stations is not supported yet (AMC 11.2.3.3).

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.

The event 01 - Audio, subevent 32 is triggered when the audio program is on.

After reset of the exchange, the audio program is restored.

Adding more Audio Programs

Each added AGA board provides 16 audio inputs for program distribution when used in AlphaCom XE20 or XE26. There can be 1 or 2 boards in a module placed in positions 20 and 21.

An AGA connection kit 1009930300 needs to be purchased to connect the audio sources. The kit contains a filter board, a connection board and an interface cable.

In an XE7 the AGA boards can be placed in board position 1- 6, but the number of channels are reduced to 6 for each board board. The input level is adjusted with potentiometers 4, 6, 8, 10, 12 and 14. The program sources are connected to the ‘c’ and ‘d’ terminals on the back plane.

Audio Program connection

As from AMC 10.50 the maximum number of program feeds for AlphaCom XE20/XE26 is extended from 38 to 70.

XE20/XE26 default program channels

APC board pos 26 program  1 -  6
AGA board pos 21 program  7 - 22
AGA board pos 20 program 23 - 38
AGA board pos 19 program 39 - 54
AGA board pos 18 program 55 - 70

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 are after autoload:

Sequence 1: Program 1, 2, 3, 4, 5, 6 and off.
Sequence 2: Program 1, 2, 3 and off.

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.

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.

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.

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
