Ethernet Standards
Various institutes and committees have been involved in establishing Ethernet data
communication standards. These specification standards assure Ethernet network compatibility
for products from a broad variety of manufacturers.
The ECOM module complies with American National Standards Institute (ANSI) and Institute
of Electrical and Electronic Engineers standard ANSI/IEEE 802.3, Carrier Sense Multiple Access
with Collision Detection (CSMA/CD) Access Methods and Physical Layer Specifications. This
standard has been adopted by the International Organization for Standardization (ISO) as
document ISO/IEC 8802-3.
The Electronic Industries Association (EIA) and Telecommunications Industries
Commercial Building Telecommunications Wiring Standard designated EIA/TIA-568A
defines implementation of 10BaseT (twisted pair) and 10BaseF (fiber optics) for Ethernet
communications.
The same two organizations produced EIA/TIA TSB40- Additional Transmission Specifications
for Unshielded Twisted-Pair Connecting Hardware. The purpose of this document is to specify
transmission performance requirements and connecting hardware requirements.
