This Recommendation | International Standard defines ACSE services for ASO-association control in an open systems interconnection environment. ACSE supports two modes of communication service: connection-mode and connectionless-mode. The ACSE connection-mode service is provided by the use of the connection-mode ACSE protocol (see ITU-T Rec. X.227 bis | ISO/IEC 15954). The ACSE connectionless-mode…

The ACSE supports two modes of communication: connection-mode and connectionless-mode. The ACSE service definition (see ITU-T Rec. X.217 bis | ISO/IEC 15953) includes both modes of communication. This Recommendation | International Standard only includes the connection mode of communication. This Recommendation | International Standard for the connectionless mode of communication is contained in…

The purpose of this part of ISO/IEC 16500 is to specify normative protocols and associated dynamic system behavior, including session and connection manipulation, configuration and download, for an ISO/IEC 16500 system. The emphasis is on the significant dynamic system entities (e.g., session control, call/connection control), the behavior of these entities (e.g., information flows, entity…

This part of ISO/IEC 16500 provides a toolbox consisting of lower layer protocols and physical interfaces. Each tool is applicable at one or more of the reference points within the delivery system. The physical delivery media that have been identified for this version of ISO/IEC 16500-4 are copper pairs, coaxial cable, microwave, fiber and satellite. Removable information carrying physical media…

Applies to the direct connection of one or more data application decoders to DAB (digital audio broadcast) receivers. Dedicated decoders for data, but also devices for audio post-processing and recording can be connected through the receiver data interface (RDI).

S'applique à la connexion directe de décodeurs d'application de données avec des récepteurs DAB (radiodiffusion sonore numérique). Des décodeurs spécifiques pour des applications de données, mais également des dispositifs destinés au post-traitement et à l'enregistrement audio peuvent être connectés à un récepteur DAB par l'interface de données du récepteur (RDI).

Optical fibre connectors for polarization maintaining fibre shall align the birefringence axes of the two mating fibres. The keying accuracy of PM connector plugs should be specified to realize PMF connection with high extinction ratio propagation. The purpose of this standard is to measure the keying accuracy of a polarization maintaining fibre connector.

1. SCOPE 1.1 This standard sets out criteria to be used when selecting uniformed contract and in-house security guards and supervisors for the protection of people, property and information. It covers requirements for contract and in-house security guards and supervisors and provides a "Security Guard Basic (Pre-Assignment) Training Program" (Appendix A), a "Security Guard…

IEC 60999-1:1999 Applies to screw-type and screwless-type clamping units for connecting devices, either as separate entities or as integral parts of equipment, for the connection of electrical copper conductors (complying with IEC 60228), rigid (solid or stranded) and/or flexible, having a cross-sectional area of 0.5 mm2 up to and including 35 mm2 and equivalent AWG sizes with a rated voltage not…

This International Standard specifies the functional requirements of a range of high-pressure pipes for use on benches for the testing and setting of fuel injection pumps intended for diesel engines. Only dimensions and requirements affecting the hydraulic characteristics of the pipes are specified. Other requirements, such as the type of end connections or shape of the pipes when bent, are not…
