ANSI/IEEE 802.5-1998 IEEE Информационные технологии - Телекоммуникации и обмен информацией между системами - местных и столичных сетей - Часть 5: маркеров метода доступа к кольцевой и спецификации физического уровня

a) Provides a general description of the token ring local area network (LAN) architecture (clause 2); b) Defines the frame format, including the delimiters, address fields, information field, and framecheck sequence (FCS). Defines the Medium Access Control (MAC) frames, timers, and error counters (clause 3); c) Defines the MAC protocols including finite state machines and state tables (clause 4); d) Defines the system level Physical layer (PHY) signaling specifications that are specific to a ring station (clause 5); e) Defines the managed objects necessary to manage the service and protocol elements that are involved in the management of a token ring station (clause 6); f) Defines the PHY station attachment specification for 4 and 16 Mbit/s operation. This includes the transmitter, receiver, medium interface connector, and transmission channel for both shielded twisted pair (STP) and unshielded twisted pair (UTP) media (clause 7); g) Defines the concentrator, incorporating multiple trunk coupling units (TCUs), for the attachment of a group of stations to the ring (clause 8);
