NTCIP 2104
Ethernet Subnetwork Profile

A subnetwork profile that defines requirements for the data link and physical layers of a communications stack. It specifies the rules and procedures for using the IEEE Link Layer Control (802.2) and Media Access Control (802.3) protocols over coaxial, twisted pair, or fiberoptic media. The intent is to provide an interoperability standard for transportation-related devices that communicate over local area network (LAN) interfaces. (Formerly TS 3.SP-Ethernet)
