NT1310 Unit 6 Assignment 1

Wire-Map Testers: The Wiremap test is used to identify physical errors of the installation; proper pin termination at each end, shorts between any two or more wires, continuity to the remote end, split pairs, crossed pairs, reversed pairs, and any other mis-wiring. It tests four-pair data and voice cable links terminated with standard, modular, eight-position RJ45 jacks. Shielded ports test both shielded and unshielded cabling. This is essential for just about any network as telephones (voice) are also used in conjunction with data communications. This tester should be a part of every cable installation kit.

Continuity Testers: This is an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the tester. The tester consists of an indicator in series with a source of electrical power - normally a battery, terminating in two test leads. If a complete circuit is established between the test-leads, the indicator is activated (the indicator may be an electric light or a buzzer).

Tone Generators: These instruments are essentially cable tracing tools. If you need to locate a specific copper cable amongst many cables, this would be the correct tool for the job. This tester is most often used to locate a specific cable on a punch-down block. Also, by testing the continuity of individual wires by using alligator clips, you could use a tone generator and probe to locate opens, shorts, and mis-wires.
