NCTI RSC II CABLE NETWORK OVERVIEW: Understanding the Feeder System Questions and Answers with Verified Solutions What is one of the differences between tree-and-branch and hybrid fiber/coax (HFC) DESIGNS? Bandwidth in the downstream path. In the tree-and-branch design, the cable signal in the downstream path leaves the trunk at the bridge amplifier. There, It makes a transition to the feeder's domain, and the signal splits. What is the maximum number of output ports the split signal can be r...

NCTI MT1-MT2 QUESTIONS AND ANSWERS 2023 According to SCTE- and NCTA- recommended trunk system map symbols, fiber-optic cable is represented by Double arrows within a small circle on a solid line. The forward path signal in a traditional tree-and-branch architecture originates at the headend and is transmitted downstream through coaxial trunk cable and trunk amplifier. In a HFC network, Processing equipment in the headend converts the forward RF signal to a light signal. ...

In the tree-and-branch architecture, how is the downstream signal from the trunk fed to the distribution branches? - Correct answer-Within each trunk amplifier, a portion of the downstream is fed to a bridger amplifier to boost the signal before being split and routed to the distribution branches. What is a common solution when congestion from modem activity and traffic becomes unacceptable in a hybrid fiber/coax (HFC) network? - Correct answer-Node splitting, the subdividing of serving ar...

What advantage is realized by increasing the voltage in a broadband cable network from 60 volts alternating current (VAC) to 90 volts? - Correct answer-Operating with 50% more voltage reduces the voltage drop and current drawn in the network for more efficient power utilization. How does surge protection at the input and output of a ferroresonant power supply defend against voltage surges? - Correct answer-By passing voltage surges (within the surge device rating) to ground without damage....
