...hat are the color orders, when i need to create physically two separated networks? 568B; straight; nic to switch: A side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown B side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown ---------- 568A; crossover; nic to nic: [it's not so important about from ~2005]: switch the pairs: 1&2 with 3&6 on one side: A side: white-green, green, white-orange, blue, white-blue, orange, white-brown, brown B side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown ---...

Actually that's not entirely true. standard 568A/B wired cable does not split pairs for ethernet or DSX1 wiring. The problem is that DSX1 uses pins (1,2),(4,5) and ethernet (1,2), (3,6) (parenthesis show pairing). DSX1 must have the (1,2) and (4,5) pairs swapped to match the TX to the RX at each end, whereas normal ethernet does not, as the...
