11.6.7. CCM with Code Conversion 
If the station numbers used for code-calling responses in the OpenScape
4000 system (answering number in the B-block) are not the same as the
search codes of the CCM, you must assign a code conversion table for
these numbers. More than one search code can be assigned to the same
station number (answering number), if required.
- Enable answering number/search code conversion for CCM
AD-TSCSU:,,DEV=PSM,,CONV=Y;
- Assign a conversion table for the CCM
AD-PERSI:TYPE=CCM,CCMSCD=key-num,STNO=number, CCNO=key-num;
