GB/T 15629.4-1997 Information processing system local area network Part 4: Token passing bus access method and physical layer specification

This part of the local area network (LAN) standard mainly discusses the various components of the token passing bus access method and its related physical signaling and media technology. In order to make the interconnection of all stations of the local area network using the token passing bus access method compatible, this standard: 1) specifies the electrical characteristics and/or optical and physical characteristics of the transmission media; 2) specifies the electrical or optical signaling method used; 3) specifies the transmission frame format; 4) specifies the actions taken by the station when a frame is received; 5) specifies the services provided at the conceptual interface between the media access control (MAC) sublayer and the logical link control (LLC) sublayer above it; 6) specifies the actions, entities and values ​​used to manage the MAC sublayer and the physical layer entity (PLE).
