This standard defines an application program interface (API) to the services of the OSI File Transfer, Access, and Management (FTAM) application-service-element. The API provides access to a set of high-level operations. That is, API functions map on to a sequence of FTAM primitives that implement the required operation. Apart from association management functions, functions that map directly onto FTAM service primitives are not provided. The API provides file transfer and file management… read more operations. File access and filestore management operations are not provided. The API supports the FTAM initiator role. The FTAM responder role is not supported. The API supports a context-free mode of operation (where the operation is performed using an FTAM association that is created specifically for the operation and destroyed once the operation is completed) and a context-sensitive mode of operation (where the FTAM association is created and destroyed independently, and operations are performed within the context of this independent association). In order to support the context-sensitive mode of operation, the API defines a set of association management functions that create and destroy FTAM associations. An implementation conforming to this standard requires support of an implementation of the services defined in IEEE Std 1224-1993 {14}. This standard is a "thick" C binding (that is, it defines both the semantics of the operations and the C language binding to those semantics). An understanding of FTAM is assumed in the remaining parts of this specification. Those unfamiliar with FTAM may wish to read Annex , Overview of FTAM (and perhaps Annex , Overview of OM) before proceeding with the remainder of this standard. read less

This standard defines requirements for test methods for measuring conformance to IEEE Std 1224.1-1993 {5}. IEEE Std 1224.1-1993 {5} is stated in terms that are independent of any particular programming language, but each implementation that conforms to it implements a particular programming language binding, and conforms to its programming language binding specification.

This is a full-use standard whose scope is to extend the already defined asynchronous and isochronous services of High Performance Serial Bus beyond the local bus by means of a device, the bridge, which consists of two nodes, each connected to a separate bus and interconnected with each other by implementation-dependent means. The project is intended to standardize the model, definition and behaviors of High Performance Serial Bus bridges, which are devices that may be used to interconnect two… read more separately enumerable buses. This project extends IEEE Std 1394-1995, as amended by IEEE Std 1394a-2000 and IEEE Std 1394b-2002, and is based upon those documents as well as upon IEEE Std 1212-2001, Control and Status Registers (CSR) Architecture for microcomputer buses. NOTE---The set of IEEE 1394 standards specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming implementations. These standards are functional descriptions. An implementation may employ any design whose behavior is compliant with the pertinent standards. read less

This part of IEC 61000 provides guidance on principles which can be used as the basis for determining the requirements for the connection of fluctuating installations to MV, HV and EHV public power systems (LV installations are covered in other IEC documents). For the purposes of this report, a fluctuating installation means an installation (which may be a load or a generator) that produces voltage flicker and / or rapid voltage changes. The primary objective is to provide guidance to system… read more operators or owners on engineering practices which will facilitate the provision of adequate service quality for all connected customers. In addressing installations, this document is not intended to replace equipment standards for emission limits. This report addresses the allocation of the capacity of the system to absorb disturbances. It does not address how to mitigate disturbances, nor does it address how the capacity of the system can be increased. Since the guidelines outlined in this report are necessarily based on certain simplifying assumptions, there is no guarantee that this approach will always provide the optimum solution for all flicker situations. The recommended approach should be used with flexibility and engineering judgment as far as engineering is concerned, when applying the given assessment procedures in full or in part. The system operator or owner is responsible for specifying requirements for the connection of fluctuating installations to the system. The fluctuating installation is to be understood as the customer's complete installation (i.e. including fluctuating and non fluctuating parts). Problems related to voltage fluctuations fall into two basic categories: * Flicker effect from light sources as a result of voltage fluctuations; * Rapid voltage changes even within the normal operational voltage tolerances are considered as a disturbing phenomenon. The report gives guidance for the coordination of the flicker emissions between different voltage levels in order to meet the compatibility levels at the point of utilisation. This report primarily focuses on controlling or limiting flicker, but a clause is included to address the limitation of rapid voltage changes. NOTE The boundaries between the various voltage levels may be different for different countries (see IEV 601-01-28) [16]. This report uses the following terms for system voltage: − low voltage (LV) refers to Un ≤ 1 kV; − medium voltage (MV) refers to 1 kV < Un ≤ 35 kV; − high voltage (HV) refers to 35 kV < Un ≤ 230 kV; − extra high voltage (EHV) refers to 230 kV < Un. In the context of this report, the function of the system is more important than its nominal voltage. For example, a HV system used for distribution may be given a "planning level" which is situated between those of MV and HV systems. read less
