Optionally an AGCX is inserted into the transmit path (see figure 68) to reach nearly
constant loudness ratings independent from the varying distance between the speaking
person and the microphone. The AGCX works only together with the speakerphone
function (GCR.SP=1).
Operation of the AGCX depends on a threshold level. The threshold is defined by the
parameter COMX (value relative to the maximum PCM-value). Regulation follows two
time constants: TMHX for signal amplitudes above the threshold and TMLX for
amplitudes below. Usually TMHX will be chosen up to 10 times faster than TMLX. The
bold line in figure Chapter 69 depicts the steady-state output level of the AGCX as a
function of the input level.
