Progression: Maintenance Tech I - II Conventional: Exam In the tree-and-branch architecture, how is the downstream signal from the trunk fed 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? What technologies are defined in DOCSIS 4.0 to help sustain the hybrid fiber/coax (HFC) network infrastructure for several more years? How can a less-experienced technician identi...

Progression: Construction Coordinator I - II Exam Answered Correctly. A chain trencher A return path sweep-and-alignment system is used to adjust which of the following? Anomalies, such as echoes and blind spots, can hide cable faults or cause a technician to misinterpret the signature of a time domain reflectometer (TDR) waveform. What causes an echo on a waveform TDR? As the RF signal travels on the coaxial cable, one portion of the signal may be attenuated more than the others. ...
