are reversed as follows:

Hot Tip!
While TIA/EIA- 568- A T568A and TIA/EIA- 568- A T568B are electrically equivalent,
care must be taken that both ends of a given cable utilize the same system. For that
reason, we strongly recommend choosing one of the two standards and using It
throughout your facility.
Standard 10Base‐T Ethernet Cable Pin‐out
Traditionally Ethernet 10Base‐ T cables use the Green and Orange pair of the TIA/EIA‐ 568‐ A
T568A or TIA/EIA‐ 568‐ A T568B wiring configuration. The full 4‐ pair TIA/EIA‐ 568‐ A T568A or
T568B configurations will work just fine (see above).
Crossover 10Base‐T Ethernet Cable Pin‐out
When connecting a 10Base‐ T device (such as a computer or the Zephyr Xstream) to a hub, a
“straight through” cable is used (see above). Note that this implies that functionality of the jacks
on the hub are different from those on the computer, since the “output” of one must
correspond to the “input” of the other. Therefore, the standard cable will not work if you wish
to connect a computer directly to the Zephyr Xstream. This can be accomplished with the special
cable below.
