A network technician crimped a length of UTP with TIA\EIA-568A on one end and TIA\EIA-568B on the other. Which of the following cable types did the technician create?
Crossover cable - 568A to 568B
Straight through is - (568A to 568A) or (568B to 568B)
A rollover cable is a complete reversal of pins - ex. (pins 12345678 to pins 87654321)
I guess if I were to get this question I'd still say Crossover but,
technically speaking, none of the answers are correct.
Yes, it's true that a crossover cable for a TIA/EIA A is very similar to the B wiring scheme. But there,s a difference.
In the A and B cables (the regular ones, not crossed over) pins 4, 5, 7, and 8 stay the same, while in their crossed version, these pins are "reflected" over pin 6...
To make it simpler to understand:
TIA/EIA-568A:
1. W/Green
2. Green
3. W/Orange
4. Blue
5. White Blue
6. Orange
7. W/Brown
8. Brown
TIA/EIA-568A Crossover:
1. White/Orange
2. Orange
3. White/Green
4. White/Brown
5. Brown
6. Green
7. Blue
8. White/Blue
Notice that TIA/EIA-568A doesn't simply "turn into TIA/EIA-568B" on its crossover version, but pins 4, 5, 7, and 8 are swapped as well.
A. Crossover cable
When a network technician crimps a length of UTP (Unshielded Twisted Pair) cable with TIA/EIA-568A on one end and TIA/EIA-568B on the other, they have created a crossover cable. A crossover cable is used to connect similar devices directly, such as connecting two computers or two switches without the need for a crossover port on a hub or switch
