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.

Hidden Channel Support
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.

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.
