The purpose of this Aerospace Recommended Practice (ARP) is to provide recommendations on the use of four types of discrete signal interfaces for unidirectional, low power, low frequency transmission of discrete information.

This SAE Aerospace Standard (AS) has been prepared by the Ring Implementation Task Group of the SAE AS-2 Committee. It is intended as a companion document to the SAE AS4075 High Speed Ring Bus Standard. While the Standard is intended to provide as complete a description as possible of an HSRB implementation, certain parameters are system-dependent and evolutionary. This document contains those parameters. The text through Table 1 is intended to provide definitions and descriptions applicable to all applications. Table 2 contains specific parameter values for one or more implementations. This table will change as new systems are implemented or new HSRB speed options are defined.

This document was prepared by the SAE AS-1A2 Committee to establish techniques for validating the Network Controller (NC) complies with the NC requirements specified in AS5653, Revision B. Note that this verification document only verifies the specific requirements from AS5653 and does not verify all of the requirements invoked by documents that are referenced by AS5653. The procuring authority may require further testing to verify the requirements not explicitly defined in AS5653 and in this verification document.

This AIR is applicable to SSPCs, EMPCs, and hybrid power controllers. It covers the control, status, BIT, etc., interfaces, other than electrical power. For the purpose of this document, a power controller shall have, as a minimum, the following characteristics: a Power switching function b Control input c Overload protection d Status feedback To accomplish the goals set forth in the Foreword, the interfaces are first categorized by function. Next, examples of actual implementations are given.

This standard establishes the design requirements for a fiber optic serial interconnect protocol, topology, and media. The application target for this standard is the interconnection of multiple aerospace sensors, processing resources, bulk storage resources and communications resources onboard aerospace platforms. The standard is for subsystem interconnection, as opposed to intra-backplane connection.

This document was prepared by the SAE AS-1A2 Committee to establish techniques for validating the Network Terminal (NT) complies with the NT requirements specified in AS5653, Revision B. Note that this verification document only verifies the specific requirements from AS5653 and does not verify all the requirements invoked by documents that are referenced by AS5653. The procuring authority may require further testing to verify the requirements not explicitly defined in AS5653 and in this verification document.

This standard specifies the characteristics of the SAE Linear Token Passing Bus (LTPB) Interface Unit. The LTPB provides a high reliability, high bandwidth, low latency serial interconnection network suitable for utilization in real time military and commercial applications. Multiple redundant data paths can be implemented to enhance reliability and survivability in those applications which require these attributes. The token passing and data exchange protocols are optimized to provide low latency and fast failure detection and correction. Physical configurations with bus lengths up to 1000 m can be accommodated.

A fault tolerant, real time high speed data communication standard is defined based on a ring topology and the use of a Token passing access method with distributed control. The requirements for the HSRB standard have been driven predominantly, but not exclusively, by military applications. Particular attention has been given to the need for low message latency, deterministic message priority and comprehensive reconfiguration capabilities. This document contains a definition of the semantics and protocol including delimiters, tokens, message priority, addressing, error detection and recovery schemes; and is written to be independent of bit rate and media. Parameters related to particular media and bit rates are defined in separate documents, the AS4075 slash sheets.

This SAE Aerospace Standard (AS) establishes the requirements for the use of IEEE-1394b as a data bus network in military and aerospace vehicles. It defines the concept of operations and information flow on the network. As discussed in 1.4, this specification contains extensions/restrictions to “off-the-shelf” IEEE-1394 standards, and assumes that the reader already has a working knowledge of IEEE-1394. This document is referred to as the “base” specification, containing the generic requirements that specify data bus characteristics, data formats and node operation. It is important to note that this specification is not stand-alone - several requirements provide only example implementations and delegate the actual implementation to be specified by the network architect/integrator for a particular vehicle application. This information is typically contained in a “network profile” slash sheet that is subservient to this base specification.
