Chapter 2 Installing the MQAM
Connect the RF OUT Ports
The RF OUT ports of the MQAM should be connected to a system of combiners,
through the cable system, and eventually to subscribers' DHCTs. Each RF port
provides for the transport of MPEG-2 TS data. The ports use F-connectors and 75 Ω
coaxial cable interfaces.
CAUTION:
Turning on the MQAM with default RF output level may cause RF
interference with the services of other units connected to the network.
Therefore, set the RF output frequency and RF output level before you
connect any RF OUT ports to the network.
Important! We strongly recommend that you configure and adjust
frequencies from the Set Up GQAM window on the DNCS. See
Provisioning the MQAM on the DNCS (on page 38) for detailed
instructions.
Location of RF OUT Ports
The following illustration shows an example of the four RF OUT ports connected to
the distribution plant.
