Jan 12, 2017 · 568A provides backwards compatibility when connecting two phone lines, 568B for only one phone line. 568B also offers a better prevention of cross talk (interference between the cable pairs). You can use either 568A or 568B, but you HAVE to use the prescribed pairings of the pins: 1 paired with 2, 3 with 6, 4 with 5 and 7 with 8!

Jan 23, 2015 · Trying figure out the key differences between T568A and T568B wiring, if any exist. I found claims in a thread that T568A has advantages over T568B due to the fact that each twisted-pair in a cat5...

Mar 21, 2018 · When you use TIA/EIA-568B on both sides this is a straight through cable. The colors of the inner jackets don't really matter, much the same as it makes no difference to the operation of the network if you use a network cable with a black or yellow outer jacket.

Oct 23, 2014 · RJ45 cable, pinned EIA-568B (not that the colors in the pinout matter) Cisco Catalyst Switch, using autonegotiation (at 100Mbps) Since the PC's NIC is locked at 100/full, the Cisco's Ethernet autonegotiation fails and it falls back to 100/half. Now there is a duplex mismatch on the line. The Cisco switch uses CSMA/CD for access to the link.
