## Music-on-hold

## Definition

External or internal subscribers waiting in park (camp‑on) state will receive music or other recorded information either during the transfer procedure only, or until the speech connection between them is established.

For the transfer of calls it can be defined by programming whether or not music will be supplied only during the transfer process or until a new speech connection is established.

## Use

Music-on-hold supplies the parked caller with park state indications (music or other recorded information) which is more pleasant than silence.

Music-on-hold is an important ingredient of ACD-, Operator- and Answering/Reroute position’s queue handling.

The music source can be a tape recorder that is connected to a free analogue trunk (BTU-A) or the audio input on the CPU-D_ board. Furthermore, it is possible to use VMU-HD or MFU board as music source for music-on-hold

## Operation

Callers transfered to an Answering/Reroute position’s‑, ACD-, or Operator queue will receive music-on- hold during transfer. Then they may receive first a voice message of the corresponding queue and then Music-on-hold until speech connection is established (depends on how the feature has been programmed; see “Voice message before answering”).

If the Answering/Reroute position is an Automated Attendant, the call rerouted to this position will receive music-on-hold until the Automated Attendant answers the call.

## Capacity

One music channel can be programmed for music-on-hold. A music channel created for music-on-hold can also be utilised for background music.

On the VMU-HD/MFU 16 different voice announcements (music titles) can be stored, one of these can be programmed to source the music channel.

## Limitations

Music is supplied in general to all external or internal callers, subject to common or individual parking, until speech connection occurs or the originator goes on-hook.

A defined music channel for music-on-hold will permanentely occupy one PCM channel in the system.

A defined music channel for music-on-hold on the VMU-HD/MFU will permanentely occupy one voice channel. A recorded music announcement on VMU-HD/MFU board can have a maximum length of 255 seconds.

## Programming

Note

For ASB 150 02 systems up to R10: To activate the programming the system has to be restarted!
For ASB 150 02 systems starting from R10: Restart of system is not necessary anymore.

## Equipment

### External music source

For the music-on-hold feature it is required that the system is equipped with an external music source (CD-player,Tape-recorder, etc.) which is connected to the audio input on the CPU-D_ board or to a free analogue trunk on the BTU-A.

### Integrated music source

In case of using the integrated music-on-hold function, it is necessary to have the system equipped with either a VMU-HD or a MFU board.

### FECU

The integrated music-on-hold function on VMU-HD/MFU is protected by the FECU which is connected to the CPU-D4. Without FECU a parking tone is faded in and a FECU warning is generated.
