1. Scope

1.1

General This part of ISO/IEC ISP 10608 is applicable to end systems and relay systems operating over FDDI LAN subnetworks in the Open Systems Interconnection (OSI) environment.

This part of ISO/IEC ISP 10608 specifies the subnetwork-type d ependent requirements for the MAC, PHY and PMD sublayers, and the Station Management function when the end system or relay system is attached to an FDDI LAN subnetwork.

1.2

Position within the Taxonomy This part of ISO/IEC ISP 10608 relates to any of the transport (Tx, Ux) or relay (Rx) profiles defined in ISO/IEC TR 10000-2, Taxonomy of OSI Profiles, where such profile uses subnetwork type 54 (FDDI Local Area Network). Specifically, this part of ISO/IEC ISP 10608 provides a common set of FDDI subnetwork require ments whenever subnetwork identifier 54 is associated with a transport group or relay type.

1.3

Scenario The scope of ISPs derived from this part of ISO/IEC ISP 10608 is limited to the end system or relay system characteristics using the FDDI Medium Interface Connector as the reference point.

The scope of this part of ISO/IEC ISP 10608 and its relation to other documents and ISP parts is illustrated in figure 1.

NOTE - Requirements for Station Management is within the scope of this part of ISO/IEC ISP 10608. However, the base standard for this function is not established yet. Therefore, this edition of ISO/IEC ISP 10608-14 does not include SMT requirements.
