The feature is activated as standard.

With the AMO command:

DIS-ZAND:TYPE=ALLDATA3;

you can determine if the feature is activated. If the value of the parameter NWTOPTIM is anything other than 0, the feature is active. The value designates the polling intervals, i.e. the intervals at which the poll is switched from one CorNet-NQ line to the next, or from one B-channel group to the next. The sequence is determined by the mapping of the physical / fictional lines in the system (i.e. the "Lines").

With the AMO command:

CHA-ZAND:TYPE=ALLDATA3,NWTOPTIM=0;

the polling is stopped, but not the feature in general. In other words, lines previously marked for the feature may still lead to new entries in the partner table. Existing entries are likewise retained. These can be deleted with the AMO KNTOP, if necessary.

If the feature has never been activated because NWTOPTIM was set to 0 in the AMO generation batch before the circuits were configured with the AMO TDCSU, the feature is generally deactivated and no entry is made in the partner table. If the feature is to be activated, the following AMO command must be entered:

CHA-ZAND:TYPE=ALLDATA3,NWTOPTIM=xx; 
(xx >0, corresponds to polling time in seconds)
