Purpose of this Document

ARINC Specification 628, Part 9, defines general architectural philosophy and aircraft infrastructure for the proper use and interface of various cabin information network related equipment. Consistency with ARINC Specification 628, Part 9, allows each respective system to operate in concert when integrated with other compatible cabin type equipment.

ARINC Specification 628, Part 9, defines standards for the aircraft Cabin Information Network (CIN) 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. Functional improvements may be made through the addition, or enhancement, of modules without modification of the aircraft.

The CIN should be designed for specific requirements but scaleable to all commercial aircraft types. A generic configuration of cabin subsystems interconnection is shown in Attachment 1, Cabin Information Network Block Diagram and Interfaces. The block diagram also includes connections with other avionics that contribute to the operation of the cabin.

The Cabin Local Area Network Internet Protocol (LAN IP) address scheme is shown in Attachment 4. This scheme includes all components and systems of the entire Cabin LAN.
