Activating the NIT processing
The NIT processing can only be activated via HE pro-
gramming software. Therefore, the option “Generate
CABLE – NIT” has to be chosen (“Design”
→
“Network
NIT”)
The
X-QAM twin 3
has no possibility to create the NIT,
the input NIT is transferred to the output. If you activate
the NIT processing, the
X-QAM twin 5
and
X-QAM twin 6
create the NIT in each channel fed by this type of card.
This NIT includes every QAM channel of the local net-
work. At “NIT – information” the parameters of the chosen
QAM bouquet are displayed.
Those information are TS-ID, ONID, output frequency,
data ratio and type of modulation.
3.3
Programming the card parameters
In the overview of the base unit, the output channels of
the X-QAM twin x – cards are chosen at “RF parameters”.
In those channels, the former QPSK bouquets are fed in
as QAM bouquets. The chosen channel is always chan-
nel A. Channel B is automatically determined as adjacent
channel of channel A.
If you now click on the “Details” button, a window opens
for configuring the card details. Here you can make the
relevant settings for the operation.
