NCTI ROC II BOOK II FINAL Test 1. When pressure testing a drop system to check for leakage, What must be done before applying the test signal? The technician must isolate the drop system from the hybrid fiber/coax (HFC) network by disconnecting the drop at the distribution tap. Why do some leakage detection systems utilize a leakage carrier modulated with a tagging signal? To avoid false detection of leaks. When all three sections of a pulse code modulator (PCM) are combined, what functio...

IT 279 UNIT 6 ASSIGNMENT 2 1. Which OSI function ensures that the identity of the remote host is verified, and that the data received is authentic? A. Routing B. Authentication C. Encryption “The Session layer (layer 5) is responsible for establishing, maintaining, and terminating communication sessions between two computers. It manages dialogue discipline or dialogue control (simplex, half-duplex, full duplex), establishes checkpoints for grouping and recovery, and retransmits PDUs t...

You want to measure the voltage, amps, and ohms of various devices. What tool would you use? - You'd use a multi-meter. what's a multimeter? - a device for testing various electrical properties. i.e. ac/dc voltage, current (amps), resistance (ohms), capacitance, and frequency. What does a voltage event recorder do? - keeps track of voltage conditions on a power line. basic recorders simply keep track of the occurrence of under/over voltage conditions, while more advanced devices track co...
