ARINC 763A

Purpose and Scope

This document provides form and fit standards for Network ServerSystem (NSS) components for installation in all types of aircraft.It defines the physical form factors, fit dimensions, low levelbuilt-in-test (BIT), data loading, and electrical interfacedefinition. Functional aspects, beyond low level BIT and dataloading, are defined in:

ARINC Report 821: Network Server System(NSS) Functional Definition

ARINC Specification 822: Aircraft/Ground IPCommunication

This document defines both wired and wireless NSS componentsthat enable the creation of airborne networks that are scalable,interchangeable, upgradeable, and remotely manageable with minimumcost. Aircraft equipment configurations and aircraft wiringrecommendations are also described to allow aircraft network growththrough the simple addition or replacement of NSS components.Hardware characteristics of standardized components are describedwithout specifying equipment capacity or the operational functionsof those components

The general characteristics of NSS equipment includestandardized packaging, connectors, electrical power, and signalinterfaces that apply to general families of network components.Equipment suppliers are free to define the hardware features ofcomponents that are designed to meet this characteristic. Intypical commercial networking fashion, the functionality of theairborne network will be defined separately by the applicationsinstalled and executed on the equipment. Software developers areencouraged to utilize the network services defined in ARINC Report821 to ensure application compatibility across the widest possiblerange of ARINC 763A implementations

The modular 2-MCU approach to NSS will enable networks onaircraft to grow and change with minimal impact on other systems.Suppliers are encouraged to create competitive ARINC 763A NSScomponents by developing new product versions that incorporate thelatest processor, storage and network technologies, thus allowingairlines to make compatible hardware choices for the design,configuration, and expansion of their airborne networks.

Example NSS architectures are provided in Attachments 5 and 6 tothis document. The NSS description includes a common file server,data processing, mass storage and interface capabilities to anumber of terminals connected via an onboard aircraft Local AreaNetwork (LAN).
