8.2.4. Generation 
IMPORTANT:
If T.38 is supposed to be used with AP 1120, G.711
must be configured as voice codec only, i.e. always in case a modem or
fax is connected to an AP 1120 the only allowed codec in the AP 1120
has to set to G.711 (no option for compression).
Before the initial configuration of an HFA user, the memory configuration
must be checked with the AMO-DIMSU:
TEST-DIMSU:LIST=Y;
Now to configure 4 modules, for example, the following configuration
must be carried out:
ADD-DIMSU:TYPE=SYSTEM,CGW=4;
The G.711 code type setting (a law or µ law) of the IP voice data
is carried out via the central system data (usually already correctly
set):
CHANGE-ZAND:TYP=CONFC,CODE=<ALAW/ULAW>;
Now the configuration of the HG 3500 module can be started.
