10.21.3. Generation (Example) 
- DSS keys are configured as follows, either with a standard or an individual
key layout:
CHA-TAPRO:STD=number,KY01=DSS,...;(standard key layout with DSS keys)CHA-TAPRO:STNO=number,STD=number,KY01=DSS,...;(individual key layout) - A DSS destination is configured as follows:
ADD-ZIEL:TYPE=DSS,SRCNO=number,KYNO=number,DESTNOD=number, DEV=param;
A special feature is implemented in conjunction with the integrated secretary system. If an executive has his secretary as the destination on a DSS key and the secretary activates the substitute secretary, the destination entry on the executive's phone is automatically assigned to the substitute and is re-assigned to the secretary again when deactivated. - To prevent DSS-keys modification by user:
CHANGE-ZANDE:TYPE=OPTISET,PROTDSS=YES;
