Audio Program

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 E20 and AlphaCom E26, and 2 audio program inputs for the AlphaCom E7. 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 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.

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:

• 790 - step up
• 791 - step down
• 792 - restore last

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
