Generic QAM Model List window 

The Generic QAM Model List window allows you to add, modify, or delete a generic 
QAM model on the DNCS.  Adding a generic QAM model to the DNCS is the first 
step in adding generic QAM modulators to the DNCS. When you add a generic 
QAM model to the DNCS, you define specifications that are unique to a particular 
model of QAM modulator. After you add generic QAM models, you can use the 
model to add an individual generic QAM modulator to the DNCS; the modulator 
will be added with the specifications of the model you used.  

 

 

The hidden channel feature has been developed for third-party application 
developers and headend technicians. This feature allows third-party developers to 
use applications that require system information (SI) data on set-tops. For service 
providers, this feature provides the ability to uniquely identify to the DNCS that a 
set-top is associated inside a network.  

Typically, the service provider designates a unique value to each DNCS by assigning 
this value in the channel number field. In turn, the set-top uses this value to 
determine which program information is displayed on the set-top. Once the channel 
is configured as hidden, it is not viewable by the subscriber. 

Refer to Configuring Hidden Channels for System Release 3.8/4.3 User Guide (part 
number 4022454) for more information on configuring hidden channels.
