Q

T568A and T568B Termination

A

Pin assignments from EIA/TIA-568-B standard.

Eight conductor 100-ohm balanced.

Twisted-pair cabling.

T568A and T568B are different pin assignments for 8P8C connectors.
Assigns the T568A pin-out to horizontal cabling.

Many organizations traditionally use 568B.

You can’t terminate one side of the cable with 568A and the other with 568B.
