7.7.3. Intelligent Multiplexer
The MUX is documented in a separate user manual. Typical broadcast applications are
described here:
4-Port Mux:
For composite STL systems, the 4-port mux (with composite option card) is used to route and
demultiplex the composite signal from the QAM demodulator.
6-Port Mux:
For discrete STL systems, the 6-port mux (with Ethernet option card) is primarily used to
interface and demultiplex the Ethernet data stream from the QAM demodulator.
