Technicolor QAM6 Application Note

Understanding and configuring the QAM6

The QAM6 is a 6 channel quadrature amplitude modulator that is expandable to 12 channels. The QAM6

can be expanded in multiples of 2 channels up to the 12 channel maximum. The channel expansion is

accomplished by means of a software license file that is downloaded to the QAM6. It is designed to work

exclusively with the COM1000 system and installs directly into the COM200 chassis. When you are

connected to a COM1000 system click on the QAM link you are taken to the QAM page.

As you can see there is a lot of information presented on this page. The page can be broken down

functionally into three main sections:

EdgeQAM Modulator



Mega-Bits Per Second



Control



EdgeQAM Modulator Section

Figure 2

The EdgeQAM Modulator section provides the user with the ability to address more than one QAM6 in

a system. It also allows the user to retrieve the log file for all the QAM6’s in the system. The formula that

is used to calculate the QAM6 IP address is 192.168.6.1+Chassis ID. In figure 2 above we can see the

QAM6 IP address is 192.168.6.11. This tells us that the Chassis ID of the chassis this QAM6 is installed in

is 10. If we were looking at a QAM6 that is installed in a chassis with a Chassis ID of 4 the QAM6 IP

address would be 192.168.6.5.

If you have more than one QAM6 in a system you would put the IP address of the QAM6 you wish to

connect to in the box on the right side and click on the Submit Query button.

To retrieve the log file for the QAM6 you are currently communicating with click on the qamLog button.

This will print the qam log buffer on the page. It can be copied and pasted into a text file, email, etc.
