Which standard defines the T568A and T568B pinouts?

Explanation:
Pinouts for T568A and T568B are defined by the TIA-568 family of cabling standards. In the current framework, TIA-568-C.2 documents the balanced twisted-pair cabling components and includes the two wiring schemes—A and B—showing exactly which color pairs map to which RJ-45 pins. This standard is the authoritative reference for terminating both ends of a copper Ethernet cable and ensuring correct pair alignment. Other standards serve different purposes: ISO/IEC 11801 covers international cabling performance requirements but does not specify the RJ-45 pinouts; IEEE 802.3 outlines Ethernet specifications and electrical characteristics but not the color-to-pin mappings; ANSI/TIA-1001 focuses on intelligent building infrastructure and related installation guidelines rather than pinouts.
