Hardware Reference Manual
4.2.3
The µ-Law compressor unit of the SICOFI
has to be considered for the total gain calculation. The accumulated gain of all
programmable transmit filters (AX1+AX2+FRX) must not exceed 7 dB if the device is set
to µ-Law operation. If the device is set to A-Law operation, then the accumulated gain
must not exceed 9 dB.
