The document discusses cable crimping and testing. It describes two types of Ethernet cables - straight cables and crossover cables. For straight cables, the wiring schematic is the same on both ends, while for crossover cables, the wiring schematic is different on each end. It then outlines the six steps to crimp and test a cable, which are: skinning the cable jacket, untwisting and straightening the wire pairs, cutting the wires, inserting the wires into an RJ45 connector, crimping the connector, and using a cable tester to check continuity.

14. Step 5 : Place the connector into a crimping
tool, and squeeze hard so that the handle
reaches its full swing.

15. Step 6 : Use a cable tester to test for proper
continuity.
