The graphic shown is a representation of a 10/100BASE-T (Auto-MDIX is not present) EIA/TIA 568 B Wiring mapped to the correct pins of an RJ-45. The representation is specifically for one end. If this Ethernet cable is to be used in connecting the same devices, what would be the correct 2-pair wire map on the other modular connector (RJ-45)?

completely invert the mappings

1 = white-green, 2 = solid-green, 3 = white-orange, 6 = solid orange

1 = white-orange, 2 = solid-orange, 3 = white-green, 6 = solid-green

Explanation

When connecting different devices in an Ethernet network, use a Cross-over cable (assuming Auto-MDIX is not present). The question requires a two-pair wire map (no all wires). The correct mapping for the other end of the cable would be, 1 = white-green, 2 = solid-green, 3 = white-orange, 6 = solid orange.
