National bodies that are members of ISO or IECparticipate in the development of International Standards through technical committees established by therespective organiza

Other international organizations, governmental and non-governmental,in liaison with ISO and IEC, also take part in the work.2) In the field of information technology,
33、 ISO and IEC have established a joint technical committee, ISO/IEC JTC1.Draft International Standards adopted by the joint technical committee are circulated to national bodies forvoting.

The physical switchcontrol allows the interconnection of multiple HIPPI based equipments with HIPPI physicallayer switches.Characteristics of this HIPPI physical switch control protocol include: support for both source routing and destination addresses; I-Fields a

This part of ISO/IEC 11518 does not protect against errorsintroduced by intermediate devices interconnecting multiple HIPPI-PHs.The purpose of this part of ISO/IEC 1
43、1518 is to facilitate the development and use of theHIPPI in computer systems by providing common physical switch control. It provides switchcontrol structures for physical layer switches interconnecting computers, high-performancedisplay systems, and high-performance, intelligent block-transfer per
