Which tool is used to force down a twisted pair conductor in an insulation displacement connection (IDC) termination? - ANSWER Punch Down tool When stripping unshielded twisted-pair (UTP) cable, what is one factor that must be taken into account to ensure proper stripping? - ANSWER Jacket thickness varies due to flame rating and manufacturer. What tool should be used to test the line cords that connect the customer premises equipment (CPE) to modular data and telephone jacks? - ANSWER An inside wire cable tester. One of the functions of the IW (inside wire) cable tester is to: - ANSWER Test line cords that connect the customer premises equipment (CPE) to modular data and telephone jacks When using a twisted-pair cable tester, a green condition means - ANSWER Continuity exists throughout the circuit pair without faults. A wiremap field cable tester can include a time domain reflectometer (TDR) to determine the distance to any breaks, shorts, or missed wires. In what situations can the tester be used? - ANSWER It is used to certify structured wiring in commercial buildings and can be used to verify inside wire (IW) in residential settings. Which of the following best describes how a wiremap tester checks pin-to-pin continuity? - ANSWER A wiremap includes one unit that injects a signal at one end of the cable and a second unit that checks the signal at the other end. What causes unshielded twisted-pair (UTP) cable to come in a variety of thicknesses? - ANSWER UTP jacket thickness varies due to flame rating and manufacturer.
