ROC I: Lesson Quizzes Only what enables set-top boxes (STB) and data over cable service interface specification (DOCSIS) modems to operate as completly separate systems that operate independent of each other? - STB and DOCSIS modems are assigned different upstream channels with different upstream channels with dedicated receivers in the headend what did the 1.1 version of DOCSIS introduce, incorporating solutions for transporting real-time data applications (such as voice traffic) over...

Broadband Digital Installer Test What information is typically stored in a signal level meter's (SLM) channel plan? - The SLM channel plan typically includes the channel number, center frequency, channel bandwidth, modulation type, and symbol rate. What advantages are there to performing automated measurements with an SLM? - Automated measurements help ensure consistent measurement practices among different technicians. What parameters of the RF carrier should be measured when diag...

Progression: Field Tech II - III Conventional Exam Questions and Answers Latest Updated 2024/2025 Graded A+. What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once? - Changing the infrastructure all at once would cause too many service disruptions. What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC) topologies? - An FTTC is allowed a smaller number of RF amplifiers between th...
