| 9.2.2 | RJ-45 jack
TIA/EIA-568-A specifies that, in a horizontal cabling scheme, you must use an RJ-45 jack for making the connection to a CAT 5 UTP cable, at the telecommunications outlet. One side of the RJ-45 jack contains eight color-coded slots. The individual Cat5 wires are punched down into the slots according to color. A firm punch down is required in order to make a good electrical connection. The other side of the jack is a female plug, which looks like a standard phone jack, except that the RJ-45 jack is larger and has eight pins.
