Inactive-Withdrawn Standard

IEEE 802.5t-2000

IEEE Standard for Information Technology--Telecommunications and information exchange between systems--Local and Metropolitan Area Networks--Part 5: Token Ring access method and physical layer specifications 100 Mbit/s Dedicated Token Ring Operation

This supplement specifies the changes required to ANSI/IEEE Std 802.5, 1998 Edition, (Base standard) and ANSI/IEEE 802.5r, 1998 Edition, and ANSI/IEEE Std 802.5j, 1998 Edition, (Amendment 1 standard) to support 100 Mbit/s Dedicated Token Ring (DTR) operation. The Base standard, together with the Amendment 1 standard, specifies shared and dedicated (point-to-point) Token Ring operation at both 4 Mbit/s and 16 Mbit/s using either the TKP Access Protocol or the TXI Access Protocol. This supplement extends Token Ring operation to 100 Mbit/s for the DTR CPort and Station using the TXI Access Protocol. Extensions to the medium access control (MAC) have been made to accommodate the requirements for high media rates (100 Mbit/s and above).

Other Activities From This Working Group

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.


No Active Projects

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.


No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


802.5-1997
IEEE Standard for Information Technology - Telecommunications and Information Exchange Between Systems - Local and Metropolitan Area Networks - Specific Requirements - Part 5: Token Ring Access Method and Physical Layer Specifications

This project will consider updates, corrections to errors and improved clarification to the Std 802.5-1995.

802.5j-1997
Token ring access method and physical layer specifications Fibre Optic Media

To upgrade from Trial Use to Full Use, the standard which adds to the token ring standard the means for fiber optic media station attachment to the token ring network. This effort will consider comments from users of the trial use standard to include specifications for both fiber for the lobe and trunk in the supplement.

802.5r and 802.5j-1997
IEEE Standard for Information technology -- Telecommunications and information exchange between systems -- Local and metropolitan area networks -- Specific requirements -- Part 5: Token ring access method and physical layer specifications -- Amendment 1: Dedicated token ring operation and fibre optic media

This amendment to Local and Metropolitan Area Network standard, ISO/IEC 8802-5 : 1998, is part of a family of local area network (LAN) standards dealing with the physical and data link layers as defined by the ISO/IEC Open Systems Interconnection Basic Reference Model. The requirements for dedicated token ring (DTR) operation are specified, including the changes and additions to the Medium Access Control (MAC) layer to provide for an additional full-duplex mode of operation (switching), and for interconnection of shared LAN segments to switch ports. Also specified are the characteristics of a fibre optic interface for connecting a 4 Mbit/s or 16 Mbit/s token ring station to the trunk coupling unit (TCU) of a token ring, including station, port, and channel requirements. Fibre optic trunk signaling recommendations are also made.

802.5v-2001
IEEE Standard for Information Technology-Telecommunications and information exchange between systems-Local and metropolitan area networks-Part 5: Token Ring access method and physical layer specifications-Amendment 5: Gigabit Token Ring Operation

This amendment specifies the changes required to IEEE 802.5, 1999 Edition (ISO/IEC8802-5:1998 base standard), IEEE Stds 802.5r and 802.5j, 1998 Edition (ISO/IEC 8802-5:1998/Amd. 1:1998), and IEEE Std 802.5t-1999, to support 1000 Mbit/s Dedicated Token Ring (DTR) operation. The base standard together with Amendment 1 specifies shared and dedicated (point-to-point) Token Ring operation at both 4 and 16 Mbit/s using either the TKP Access Protocol or theTXI Access Protocol. IEEE Std 802.5t-2000 extends Token Ring operation to 100 Mbit/s for the DTR C-Port and Station using the TXI Access Protocol. This standard extends Token Ring opera-tion to 1000 Mbit/s for the DTR C-Port and Station using the TXI Access Protocol. Extensions to the Media Access Control have been made to accommodate the requirements for the 1000 Mbit/s media rate.

802.5w-2000
IEEE Corrigenda to Standard for Information Technology - Telecommunications and information exchange between systems - Local and metropolitan area networks - Part 5: Token Ring access method and physical layer specifications

Withdrawn September 2008. This corrigendum to Local and Metropolitan Area Network standards, IEEE Std 802.5, 1998 Edition and IEEE Stds 802.5r and 802.5j, 1998 Edition, is part of a family of local area net-work (LAN) standards dealing with the physical and data link layers as defined by the ISO/IEC Open Systems Interconnection Basic Reference Model. Errors that have been identified in the two standards are corrected.
