This International Standard specifies the characteristics of a 130 mm optical disk cartridge (ODC) of Type WORM (Write Once Read Many) with a capacity of 5,2 Gbytes. Type WORM ODCs use writing effects that are inherently irreversible. Written marks cannot be erased and attempted modification of the written marks are detectable. This International Standard specifies _ the conditions for…

This International Standard defines how user oriented performance of computer-based software systems (CBSS) may be measured and rated. A CBSS is a data processing system as it is seen by its users, e.g. by users at various terminals, or as it is seen by operational users and business users at the data processing center. A CBSS includes hardware and all its software (system software and…

This Recommendation | International Standard provides the specification of management information within an Open System related to those operations of the OSI Physical Layer specified by the specifications in this Recommendation | International Standard. Specifics on how Physical Layer management is accomplished is beyond the scope of this Recommendation | International Standard. Physical Layer…

This International Standard specifies the logical specifications of STbus which is a high-performance and highly reliable system bus. STbus adopts a synchronous transfer method with a high-speed clock and a split transfer method enabling to minimize bus holding time during one bus operation and to use a bus efficiently. This International Standard is applicable to a high-performance system bus or…

This International Standard specifies requirements for epoxy powders for use in preparing fusion-bonded epoxycoated steel reinforcing bar, wire and welded fabric. This International Standard also includes requirements for sealing material used to repair damaged areas and cut ends on reinforcing steel. This International Standard defines a flexible (type A) coating and a nonflexible (type B)…

This International Standard specifies the essential dimensional requirements for size "S" fuel nozzles used in diesel engines. These requirements allow the assembly and interchangeability of the nozzles in the corresponding nozzle holders. This International Standard is applicable to size "S" nozzles, which comprise hole type, long-stem nozzles (types A1 and A2) and pintle…

This Recommendation | Technical Report specifies the means by which the administrator of various aspects of an MHS system may configure information into the directory for MTAs to use to determine the routing of messages. ITU-T Rec. X.412 | ISO/IEC 10021-10 provides a set of directory structures that may be configured in many different ways to support a particular MHS routing strategy. In order to…

This Recommendation | International Standard defines the Message Store abstract-service. This abstract-service is provided by the Message Store access protocol (specified in ITU-T Rec. X.419 | ISO/IEC 10021-6) in conjunction with the MTS abstract-service (defined in ITU-T Rec. X.411 | ISO/IEC 10021-4), together with the Remote Operations Service Element (ROSE) services (defined in ITU-T Rec. X.…

This Recommendation | International Standard is one of a series on message handling. The entire set provides a comprehensive blueprint for a Message Handling System (MHS) realized by any number of cooperating open systems. The purpose of an MHS is to enable users to exchange messages on a store-and-forward basis. A message submitted on behalf of one user, the originator, is conveyed by the…
