The units and components which furnish a means of entertaining the passengers and providing communication within the aircraft (cabin intercommunication data system (CIDS)), and between the aircraft cabin and ground stations (cabin network service (CNS)). These include voice, data, music and video transmissions.
The CIDS provides an interface between cockpit/cabin crew and cabin systems. These systems support data exchange of the different related Line Replaceable Units (LRUs) and they are typically operated via Flight Attendant Panels (FAPs).
The CNS is typically on a server, interfacing with systems, including the following:
      * data/radio communication
      * cabin core system (CCS)
      * in-flight entertainment system (IFES)
      * external communication system (ECS)
      * cabin mass memory system (CMMS)
      * cabin monitoring system (CMS)
      * miscellaneous cabin systems (MCSs).
The CNS may host functions such as the following:
      * access to pre-departure/departure reports
      * email/intranet/internet access
      * passenger database.

The units and components which furnish a means of storing, updating and retrieving digital information, traditionally provided on paper, microfilm or microfiche. These include units that are dedicated to the information storage and retrieval function, such as the electronic library mass storage and controller. But they do not include units or components installed for other uses and shared with other systems, such as flight deck printer or general use display.
Typical examples include the following:
