Verification Methods for AS5653 Network Terminal

2019-04-24
CURRENT
AS6088
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.

Linear Token Passing Multiplex Data Bus

2017-02-21
CURRENT
AS4074B
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.

Pi-Bus Handbook

2012-05-03
CURRENT
AIR4903A
This section defines the scope of the document, provides a brief history of the Pi-Bus, discusses key features of the Pi-Bus, and provides an overview of the operation of the Pi-Bus. This document is a handbook intended to accompany AS4710 Pi-Bus standard. The purpose of this document is to provide information to aid users of the Pi-Bus, whether they be implementors of Pi-Bus controllers, architects of systems considering using the Pi-Bus, or programmers who must develop applications in a system which uses the Pi-Bus as the backplane communications bus. This document also provides rationale for many of the Pi-Bus requirements as defined in AS4710 and a discussion of potential enhancements that are being considered for the Pi-Bus.

Handbook for the SAE AS4075 High Speed Ring Bus Standard

2012-05-03
CURRENT
AIR4289A
This Handbook has been prepared by the Ring Implementation Task Group of the SAE AS-2 Committee, and is intended to support AS4075 by providing explanation of the standard itself and guidance on its use. The principal objective in the preparation of a standard is to provide a statement of operational and performance requirements, and an unambiguous definition of the functions to be realized in any implementation, primarily from the view point of interoperability. While efforts have been made within the AS4075 standard to provide a readable general description of the HSRB, detailed explanations, rationale and guidance to the use are incompatible with the purpose and, indeed, the format of a standard. Accordingly, this Handbook contains a paragraph-by-paragraph explanation of the main sections of the standard, and a discussion of application and implementation issues.

High Speed Ring Bus (HSRB) Standard

2012-05-03
CURRENT
AS4075A
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.

Serial Hi-Rel Ring Network for Aerospace Applications (RingNet)

2010-03-09
CURRENT
AS1393
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.

IEEE-1394b Interface Requirements for Military and Aerospace Vehicle Applications

2006-10-13
HISTORICAL
AS5643A
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.
