QAM6 Overview
The QAM6 card is an Edge QAM that is installed directly into a COM360 chassis. It
connects to the COM46 cards via a GigE connection on the back edge of the card.
The board provides 12 QAM modulators in addition to the front 1 0 0 m b p s Ethernet port,
which can be used to manage the COM2000 system.
Each QAM channel can carry up to 3 HD or 8 SD video channels. When shipped from the
factory the QAM6 boards will only permit six QAM carriers to be active at a time. To
increase the number of QAM carriers, additional SWQAM2 licenses must be purchased from
your distributor and downloaded to the QAM6. Each license enables 2 more QAM carriers
per board up to a total of 12 carriers.
A COM360 chassis fully populated with COM46 receivers (48 channels total) requires 16 QAM
channels (3 HD channels per QAM). This requires 2 QAM6 modulators (12 QAMS) plus 2
additional SWQAM2 upgrade licenses. Additional SWQAM2 upgrades can be purchased for a
maximum of 24 QAM channels. These can be utilized for additional services such as ATSC-8, or
externally sourced video streams.
A front view of the QAM6 can be seen in Figure 59 below in figure.
