Backbone Cabling is the inter-building and intra-building cable connections in structured cabling between entrances. 3. Patch Cords:
Insulated cord with a plug at each end, for use with a patch panel. 4. Connectors:
Cable connectors are devices for keeping two parts of an electric circuit in contact. 5. Conduit:
A tube or trough for protecting electric wiring: "the gas pipe should not be close to any electrical conduit". 6. Racks:
In the electrical wiring of buildings, a cable tray system is used to support insulated electric cables used for power. 7. Punch-Down Blocks:
Type of electrical connection often used in telephony; it is named because the solid copper wires are "punched down" into short open-ended slots which are a type of insulation-displacement connectors. 8. Consolidation Points:
Location where consolidation of consignments takes place.

Is an electronic device used to verify the electrical connections in a cable or other wired assembly? Generally a cable tester consists of: 1. A source of electric current,
2. A volt meter,
3. A switching matrix used to connect the current source and the volt meter to all of the contact points in a cable. A cable tester is used to verify that all of the intended connections exist and that there are no unintended connections in the cable being tested
12. Continuity tester:
Determine if an electrical...
