ARINC 765 PDF

Purpose: This document defines an Ethernet Switch Unit which fits in the general architectural philosophy and aircraft infrastructure for the proper use and interface of various information network related equipment. Equipment conforming to this document enables each respective equipment to operate in concert when integrated with other relevant equipment.

This document is intended to be used in conjunction with ARINC Specification 628: Cabin Equipment Interfaces (CEI), Part 9, Cabin Management and Entertainment System, Cabin Information Network and other aircraft systems.

ARINC Specification 628 Part 9 defines standards for the aircraft Cabin Information Network wiring, connectors, power, identification codes, space envelopes, and mounting principles. The equipment itself is not the subject of this specification because it may be unique to the system manufacturer or marketplace-driven. Design guidelines are included for informational purposes as these guidelines impact the interfaces and installation of cabin equipment aboard the aircraft.

A generic configuration of cabin subsystems interconnection is shown in the "Cabin Information Network Block Diagram" (see Attachment 1 to ARINC Specification 628 Part 9). The block diagram also includes connections with other systems that contribute to the operation of the aircraft network.
