Data Sheet

Voice data is transferred in 16 bit linear coding in two bidirectional channels C
1
and C
2
.
For controlled loudhearing an auxiliary channel C
3
is used to transfer the current setting
of the loudspeaker amplifier ALS to the PSB 4860. The remaining bits are fixed to zero.
In the other direction C
3
transfers an override value for ALS from the PSB 4860 to the
PSB 4851. An additional override bit OV determines if the currently transmitted value
should override the AOAR:LSC setting. The AOAR:LSC setting is not affected by C
3
:ALS
override. Table 2-2 shows the source control of the gain for the ALS amplifier.
Therefore the PSB 4860 can control the gain of the loudspeaker amplifier (ALS)
independently from the gain of the handset amplifier (AHS) as shown in figure 2-7.
