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.
