3.4 GbE Card

The COM360 chassis has an integrated 14 port Ethernet switch on the backplane. This switch

provides gigabit speed on two external ports as well as all card slots. The GbE card was designed

for the legacy COM200 chassis which only had one external GbE port that is not available once

a QAM6 is installed. Since two GbE ports are always available on a COM360 the GbE card is

not needed to interconnect multiple COM360 chassis.

Deprecated. This card is no longer supported.

3.6 QAM6 Board

The QAM6 card is an Edge QAM that can be installed directly into a COM360 chassis. It

connects to the COM46 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

COM2000 system. Each QAM channel can carry 2 - 3 HD or 8 SD video channels. A COM360

chassis fully populated with COM46 receivers (48 channels total) requires 2 QAM6 modulators

updated to 12 channels with SWQAM2 upgrade licenses. A front view of the QAM6 can be seen

in Figure 7.

The QAM6 outputs three unique channel-grouping of four channels each according to the EIA

North American Cable Television Frequency Plan (see EIA-542B) from the front RF connector.

The four channels within each channel-grouping must be adjacent to one another and within the
