Electromagnetic Compatibility and Radio Spectrum Matters (ERM); Terrestrial Flight Telecommunication System (TFTS); Part 1: Speech Services@ Facilities and Requirements (Second Edition)
This 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 pan-European terrestrial aeronautical public correspondence service. This ETS contains the 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 radio interface and Terrestrial Flight Telecommunication System (TFTS) ground network required to maintain inter-operability of equipment. ERC Decision ERC/DEC/(92)01 [1] is applicable to the TFTS frequency spectrum within Europe. This ETS includes a general description of the TFTS which is of informative 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 [11]. The commercial aspects of service definition are outside the scope of this ETS except where it is necessary for this information 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 specified for uplink calling@ facsimile@ data services and low rate speech services.
