17、ean T elecommunication Standard (E TS) has been produced by the Electromagnetic compatibility and Radio spectrum Matters (ERM) Technical Committe e of the European Telecommunications Standards Institute (ETSI). This ETS has been split into three parts as follows: Part 1: Part 2: “Speech services, fa
18、cilities and requirements“; “Speech services, radio interface; Part 3: “Speech services, network aspects Transposition dates Date of adoption of this ETS: Date of latest announcement of this ETS (doa): 24 July 1998 31 October 1998 Date of latest publication of new National Standard or endorsement of
19、 this ETS (dop/e): 30 April 1999 I Date of withdrawal of any conflicting National Standard (dow): 30 April 1999 I Introduction The Terrestria I Flight Telecommunication System (TFTS) aircraft station was specified by the European Airlines Electronic Co mmittee (EAEC) and has subsequently been adopte
20、d as Aeronautical Radio Incorporated (ARINC) Characteristic 752 2 by the Airlines Electronic Engineering Committee (AEEC). ARINC Characteristic 752 2 makes reference to this ETS for the specification of certain radio and telecommunication matters to avoid ambiguity. The TFTS aircraft station is one
21、of a set of facilities within an overall architecture being defined for aircraft on-board telecommunications by the AEEC. There are supplementar y specif ications defining the provision of functions or services outside the scope of this specification. Page 7 ETS 300 326-1 : August 1998 1 Scope This
22、European Telecommunication Standard (ETS) specifies the minimum technical requirements of the services, facilities and functions that the Terrestrial Flight Telecommunication System (TFTS) supports to provide a pawEuropean terrestrial aeronautical public correspondence service. This ETS contains the
23、 specification of equipment for the provision of a terrestrial aeronautical public correspondence service working in the frequency spectrum bands allocated at World Administrative Radio Conference 1992 (WARC 92) (1 670 to 1 675 MHz and 1 800 to 1 805 MHz). This ETS fully specifies aspects of the rad
24、io interface and Terrestrial Flight Telecommunication System (TFTS) ground network required to maintain inter-operability of equipment. ERC Decision ERC/DEC/(92)01 l is applicable to the TFTS frequency spectrum within Europe. This ETS includes a general description of the TFTS which is of informativ
25、e nature. The specification of data application and facsimile is the subject of ES 200 794 12. The delivery mechanism for Packet Data Services is defined in ETS 300 752 i 11. The commercial aspects of service definition are outside the scope of this ETS except where it is necessary for this informat
26、ion to be considered due to its impact on technical specification matters. The scope of this part of the ETS has been confined to the set of services to be provided by the phase 1 standard. An informative subclause 5.4 has been included describing the service definitions that may subsequently be spe
27、cified for uplink calling, facsimile, data services and low rate speech services. 2 Normative references This ETS incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications listed her
28、eafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. ERC Decision ERC/DEC/(92)01 (1991): Decision on

The basic TFTS architecture is described together with a brief explanation of the various functional entities of the system. When appropriate, referenc
44、e is made to other parts of this ETS where more detailed descriptions of functional entities are provided. Reference has also been made to possible connections to external systems which are beyond the scope of this ETS. These references are not intended to imply any technical or commercial implement
45、ation for the service provided by TFTS. 4.1 Purpose of the TFTS The TFTS provides a radio communication link between aircraft and ground stations which have access to public fixed telecommunications networks. This enables aircraft passengers or users to access public telecommunications services from
46、 the air. The principal services supported by the TFTS are as follows: a) telephony; b) facsimile group 3; c) paging services; d) data services. The services provided by TFTS are primarily aimed at commercial airliners but this does not preclude use of the system by smaller commercial regional aircr
47、aft operators or the general aviation sector. 4.2 Service coverage The radio system of the TFTS is similar in nature to the cellular systems of the land mobile service. There are some important differences, especially the cell radii (typically 240 km) and the height coverage (in excess of 43 O00 fee
48、t). The mobiles of the service are aircraft in flight or on the ground in the starting or finishing phases of flight. Three cell types are specified: en-route: providing a large area coverage at altitude; intermediate: providing coverage at lower altitude where required, especially in the vicinity o
49、f airports; and airport stations: for use on or immediately above the ground.
