## Background Music

## Definition

In idle state extension users equipped with system telephones may listen to music or other information via the monitoring loudspeaker.

## Use

Background music can be used to listen to various forms of recorded music, the radio or other information.

The music/information source can be connected to a free trunk.

If the same source is used both for music-on-hold and background music, the source can be connected to audio-input on the CPU-D_ board.

## Operation

### System Telephones

#### Connection

Connection of background music is achieved as follows:

- Dial selected number of the facility

or

- Press programmed name selection key

#### Disconnection

Disconnection of background music:

- Press Clear-key (Operator’s Console: Press Loudspeaker-key)

or

- Dial directory number again

or

- Press programmed name-key

The lamp for Line 1 is seized during the key sequence but is disconnected immediately thereafter.

The Loudspeaker and Mute lamps lights and glows steadily when background music is connected.

The volume of the background music can be adjusted by means of the + and --keys on the telephone.

#### To change the music channel

If several channels exist, a new channel can be connected directly by dialling the directory number of the new channel.

## Capacity

There can be a maximum of three music / information channels. Furthermore, a music channel can be created for music-on-hold. See also under "Music-on-hold", document 343/155 34-ASB 150 02 Uen.

## Limitations

Background music does not seize (occupy) any traffic function key.

When an incoming call is presented or on initiation of a call, background music will be disconnected automatically.

Background music returns immediately when the telephone has returned to idle state.

Only external connected audio equipment can be assigned as background music source.

## Equipment

Background music requires an external music source and an analogue trunk (BTU-A_) per music source. If the background music uses the same source as music-on-hold this can be connected to the audio-input on the CPU-D_ board.

Please note that Background music does not work on the subequiped version of the BTU-A_. Regarding the necessary DIP-switch settings on the BTU-A_, please refer to document Installation Instruction, ASB 150 02 document 1531-ASB 150 02 Uen.
