scope:

General

This part of ISODEC ISP 10608 is applicable to End Systems or Relay Systems operating over Token Ring LAN subnetworks in the Open Systems Interconnection (OSI) environment.

This part of ISO/IEC ISP 10608 specifies the subnetwork-type dependent requirements for the MAC Sublayer and the Physical Layer when the End System or Relay System is attached to a Token Ring LAN.

Position within the Taxonomy

This part of ISODEC ISP 10608 relates to any of the transport (Tx, Ux) or relay (Rx) profiles defined in ISO/IEC TR 10000-2, Taxonomy of OS1 Profiles, where such profile uses subnetwork type 53 (Token Ring Local Area Network). Specifically, this part of ISODEC ISP 10608 provides a common set of requirements that are applicable to Transport Groups TA, TB, TC, TD, TE, UA, and UB, and to Relay Types RA, RB, RC, RD, RE, and RZ whenever subnetwork identifier 53 is associated with the transport group or relay type.

Scenario

The scope of ISPs derived from this part of ISODEC ISP 10608 is limited to the End System or Relay System characteristics using the Medium Interface Connector (MIC) as the reference point. Information relating to suitable media types and installation procedures for a Token Ring trunk cabling system may be found in the document referenced in the informative annex B to this part of ISODEC ISP 10608.

The scope of this part of ISO/EC ISP 10608 and its relation to other documents and ISP parts is illustrated.
