Figure 5 - COM24FLX Card
3.5 GbE Card
The COM200 chassis has an integrated Ethernet switch on the backplane. This switch provides
gigabit speed on two ports. One of those is the port on the back of the chassis the other is card
slot number one. The gigabit port that is available on the back of the chassis is the port that the
QAM24 card uses when it is installed. In order to daisy chain chassis or to inject large amounts
of data to the QAM24 in a Colony system you would need another gigabit port and that is where
the GbE card comes in. By replacing the card in slot one with the GbE card you now have
another gigabit speed Ethernet port that can be used to route data to the QAM24 card in that
chassis. This card is also required for use of the ATSC8 receiver in the system if the QAM24 or
QAM6 modulator is used.
3.6 XDR24 Card
The XDR24 card is currently being deprecated. For additional support contact your equipment
vendor or Technicolor.
3.7 QAM24 Board
The QAM24 card is an Edge QAM that is installed directly into the COM200 chassis. It connects
to the COM24 cards via a GigE connection on the back edge of the card. This optional card
replaces the Ethernet Card in the upper left side of a COM200 Chassis. The board provides 12
QAM modulators in addition to the front Ethernet port, which can be used to manage the
SWM Input
