ARINC 628P1-5

Purpose of this Document

ARINC Specification 628 defines general system architecturalphilosophy and specific design guidance for the design andinterface of various cabin related equipment. Compliance with ARINCSpecification 628 allows each respective ARINC equipment standardto interoperate when integrated with other relevant equipment.System performance parameters are described herein for connectors,electrical interfaces, operational mode control/protocols, BITEreporting, reliability, environmental conditions, and software dataloading.

Cabin subsystems are becoming more sophisticated and complex.This is due primarily to the passenger entertainment and serviceimprovements to enhance passenger comfort. Almost unlimitedselections of audio and video programming are available to thepassengers. State-of-the-art video entertainment subsystems with acapability for video games and catalog viewing are being providedon a personalized basis. Passengers can communicate almost anywherein the world via a telephone at their seat. Office type computingsystem and peripherals are also finding their applications in thecabin to facilitate data handling and management, and to link cabindata communication to the ground.

Standardization will enable the airlines to reap the benefits ofthese improvements. These benefits are achieved through greaterairline freedom of choice, unit price reduction through increasedvolume, interchangeable spares and greater availability of spares,more upgradeable options and creating more sub-markets forintegrators and software/hardware suppliers.

Each subsystem may embody design features that are airlineunique. Due to the unique nature of some equipment, only interfacesare standardized. Some functionalities are recommended as thedesign guidelines only.

Cabin subsystems should be managed, controlled and maintainedsystematically. Integration of management and control databuses/protocols is desirable to prevent proliferations of controlpoints in the cabin. Centralizing management and controls of thedifferent cabin subsystems facilitates operation, maintenance, andtroubleshooting significantly.
