(ARINC)and thePurpose of ARINC CharacteristicsAeronautical Radio, Inc. is a corporation in which the United States

6、scheduled airlines are theprincipal stockholders. Other stockholders include a variety of other air transport companies, aircraftmanufacturers and non-U.S. airlines.Activities of ARINC include the operation of an extensive system of domestic and overseasaeronautical land radio stations, the fulfillm

7、ent of systems requirements to accomplish ground andairborne compatibility, the allocation and assignment of frequencies to meet those needs, thecoordination incident to standard airborne communications and electronics systems and the exchange oftechnical information. ARINC sponsors the Airlines Ele

8、ctronic Engineering Committee (AEEC),composed of airline technical personnel. The AEEC formulates standards for electronic equipment andsystems for the airlines. The establishment of Equipment Characteristics is a principal function of thisCommittee.An ARINC Equipment Characteristic is finalized aft

9、er investigation and coordination with theairlines who have a requirement or anticipate a requirement, with other aircraft operators, with theMilitary services having similar requirements, and with the equipment manufacturers. It is released as anARINC Equipment Characteristic only when the interest

10、ed airline companies are in general agreement. Such a release does not commit any airline or ARINC to purchase equipment so described nor does itestablish or indicate recognition of the existence of an operational requirement for such equipment, notdoes it constitute endorsement of any manufacturers

11、 product designed or built to meet theCharacteristic. An ARINC Characteristic has a twofold purpose, which is:(1) To indicate to the prospective manufacturers of airline electronic equipment theconsidered opinion of the airline technical people, coordinated on an industry basis,concerning requisites

12、 of new equipment, and(2) To channel new equipment designs in a direction which can result in the maximumpossible standardization of those physical and electrical characteristics which influenceinterchangeability of equipment without seriously hampering engineering initiative.iARINC CHARACTERISTIC 7

20、IPTION1.1 Purpose of this CharacteristicThis document defines the desired Characteristics of theTerrestrial Flight Telephone System (TFTS) for all types ofcommercial transport aircraft. The intent of this documentis to provide guidance on the form, fit and function for theinstallation of the airborn

21、e radio sub-system MPU,Transmitter-Receiver (T/R), diplexer and antenna. It alsoprovides functional and interfacing guidelines with theobjective of ensuring that compliant equipment willconform to the European Telecommunications Standard(ETS) 300-326 for the signal in space and groundenvironments.CO

22、MMENTARYEquipment manufacturers should note that thisdocument encourages them to produce highly reliableequipment rather than that of minimum weight andsize. They are at liberty to accomplish this objectiveby means of the techniques considered mostappropriate. Airline customers are interestedprimari

23、ly in the end rather than the means.Manufacturers should note that although thisCharacteristic does not preclude the use of standardsdifferent from those set out herein, the practical problemsof redesigning a standard airframe installation toaccommodate a special equipment could very well makethe us

24、e of that equipment prohibitively expensive for thatcustomer. They should recognize, therefore, the practicaladvantages of developing equipment in accordance withthe standards set forth in this document.COMMENTARYThis Characteristic has been written assuming thattransmission and reception of the sig

25、nal in space istransmitted at L Band frequencies, specifically in therange 1670 to 1675MHz (Ground to Air) and 1800 to1805MHz (Air to Ground).Aircraft altitude information is required for activeradio cell management. The ETSI standard states,“An Aircraft Station AS should not select orcontinue to us

26、e an En-Route (ER) or Intermediate(INT) Ground Station (GS) if the aircraft altitude isgreater than the MAXALT. If altitude information isnot available, the AS should only use an ER or INTGS if its MAXALT is greater than or equal to 40,000feet.” The upper limit for MAXALT available at thetwo types o

27、f GS are ER greater than or equal to 43,000feet and INT equal to 15,500 feet.1.2 Related DocumentsThe latest revision of the following documents arepertinent to the design of equipment intended to meet thisstandard.ARINC Report 413A, “Guidance for Electrical PowerUtilization and Transient Protection

32、eservice (aeronautical passenger communications) to airlinepassengers and perhaps Airline OperationalCommunication (AOC) and Airline AdministrativeCommunications (AAC) through a network of groundstations distributed throughout Europe. In addition totelephone service, non voice services should be mad

33、eavailable. The primary means of charging the passenger isthrough a credit card, which is read by the cabin terminalequipment prior to the call being connected. Alternativemeans of call billing may be arranged between the aircraftoperator and the service provider. This Characteristicaddresses the re

34、quirements for the airborne equipment inorder to allow a common aircraft installation.1.4 Airborne Avionics ConfigurationsThe airborne subsystem is modular in form, providingcommunications capacity in blocks of four circuits.COMMENTARYA large, wide bodied aircraft may require two blockswhile a small

35、er aircraft may need only one. Theequipment fit should consist of:c-1c-1c-1ARINC CHARACTERISTIC 752 Page 21.0 INTRODUCTION AND DESCRIPTION1.4 Airborne Avionics Configurations (contd)UNIT QUANTITY4 Circuit 8 CircuitAntennaDiplexer 1 2T/R 1 2MPU 1 2Control Panel 1 1CTU 1 1Handsets as requiredCOMMENTAR

36、YThe capacity referred to above assumes the use of a9.6 kbps Codec. When a suitably approved 4.8 kbpsCodec becomes available the traffic capacity of theTFTS system may be increased and ultimatelydoubled.The control panel is an optional item, to be fitted atthe discretion of the individual airline. T

37、he CabinCommunications Unit (CCU) and handsets aredescribed in ARINC Characteristic 746.1.5 Unit Descriptions1.5.1 Modem Processor UnitThe Modem Processor Unit (MPU), which includes theCodecs, provides two important functions to the system. The first is the modulation and demodulation of the signali

38、n space, and the second is the hosting of the softwarethat automatically selects the ground station andmaintains the radio connection for the duration of the call.1.5.2 Transmitter ReceiverThe Transmitter Receiver (T/R) is a full duplex radiooperating in the band allocated to the TFTS, 1670 to 1675M

39、Hz (receive) and 1800 to 1805 MHz (transmit). The T/Rincludes a second receiver that monitors other groundstations to provide information that can be used to makedecisions concerning handover and other network issues.1.5.3 DiplexerThe diplexer is a passive device connected between theT/R and the ant

40、enna. It combines the transmitter outputof the radio with the receiver input such that a commonantenna can be utilized. It provides filtering to protect thereceiver from its own transmissions and to minimizeinterference to and from other equipment on the aircraft.1.5.4 AntennaThe antenna is a small

41、aerodynamic blade providingpredominantly vertical polarization over an omnidirectionalpolar diagram. It is designed to use the footprint asshown in Attachment 1-2.1.5.5 Control PanelThe Control Panel (CP) is an optional item providing selftest facilities (BITE initiate and display) and the MPUdisabl

42、e function.1.6 InterchangeabilityThe interchangeability objectives are such that equipmentfrom any source should be able to fit into the standardinterwiring. It is not required, however, that a T/R fromone manufacturer will operate with an MPU from another.1.7 Regulatory ApprovalThe TFTS equipment s

43、hould meet the applicableregulatory approval requirements as defined by theappropriate National Regulatory Authority (e.g., UKCAA). This is not within the scope of this Characteristic.COMMENTARYSince the TFTS equipment is not classed as essentialavionics equipment and its interface with other onboar

44、d systems is likely to be minimal, the approvalrequirements are likely to be less onerous than foressential avionics equipment.1.8 Conformance TestingAs a telecommunications system having to interwork withpublic European telecommunications networks, the TFTSequipment should meet the conformance test

45、ingrequirements expressed in ETS ESTI ETS XXX YYY.COMMENTARYThe essential elements include the following aspects:a. User safety.b. Safety of Telecommunications Operators.c. Electromagnetic compatible.d. Protection of the public networks from harm.e. Effective use of the radio spectrum.f. Interworkin
