—>  All QAM cassettes must be set and ready for reception!

 

—>  The NITs of all QAM cassettes are switched on.

 

—>  The cassette gets all the information it needs (output frequencies, output 

symbol rates etc.) to generate the cable NIT from all the QAM cassettes. 
This process may take a few seconds.

 

 

The display shows: "

—>  Then the cable NIT is generated, added and sent to all QAM cassettes. 

The other QAM cassettes also add this new cable NIT. The status of all 
QAM cassettes in the NIT menu changes to "

—>  The cable NITs of the other QAM cassettes remain activated. When the 

cable NIT of the cassette is reactivated ("

on

NIT is added again. If parameters have been changed in the meantime, 

you must select "
