ARINC791P2-2 791P2-2 Mark I Aviation Ku-Band and Ka-Band Satellite Communication System, Part 2, Electrical Interfaces and Functional Equipment Description

This document (ARINC Characteristic 791, Part 2) provides the non-networking interface definition of the Mark I (ARINC 791) and Mark II (ARINC 792) Ku-Band and Ka-Band Satellite Communication (satcom) system intended for passenger entertainment on commercial transport aircraft.

ARINC Characteristic 791 Part 1 of this document provides an overview of Ku-band and Ka-band satcom systems. System provisions, including Line Replaceable Unit (LRU) form factors, attachments, cooling, and inter-system wiring, are defined. Signals between the Modem/Modem Manager (Modman) and the Antenna Subsystem are described to permit interchangeability between any Modman and any Antenna Subsystem.

ARINC Characteristic 791 Part 2 of this document provides the non-networking interface definition of the satcom system. Any signal crossing into or out of the communication system is documented to ease aircraft integration. Signals within the satcom system, and in particular, between the Modman and the Antenna Subsystem, are described to permit interchangeability between any Modman and any Antenna Subsystem.

ARINC Characteristic 791 Part 3 of this document provides the networking interface definition of the satcom system. Any signal crossing into or out of the communication system is documented to ease aircraft integration.
