VHF air-ground Digital Link (VDL) Mode 4 radio equipment - Technical characteristics and methods of measurement for ground-based equipment - Part 4: Point-to-point functions
The present document applies to the following radio equipment types:
1) Very High Frequency (VHF) Digital Link (VDL) Mode 4 ground-based radio transmitters and receivers for air-ground communications operating in the VHF band, using Gaussian-filtered Frequency Shift Keying (GFSK) Modulation with 25 kHz channel spacing and capable of tuning to any of the 25 kHz channels from 118,000 MHz to 136,975 MHz as defined in ICAO VHF Digital Link (VDL) Standards and Recommended Practices (SARPs) [8]. The present document provides part 4 of the technical specifications. The present document is designed to ensure that equipment certified to it will be compatible with the relevant ICAO VHF Digital Link (VDL) Standards and Recommended Practices (SARPs) [8] and VDL Mode 4 Technical Manual (TM) [1]. Manufacturers should note that in future the tuning range for the ground transceivers may also cover any 25 kHz
channel from 108,000 MHz to 117,975 MHz. The scope of the present document is limited to ground stations. The equivalent specification for airborne stations is EN 302 842 [7]. A description of the scope of the VDL Mode 4 system is provided in part 2 of these technical specifications (see EN 301 842-2 [5], clause 1). EN 301 842-1 [4] deals with tests of the physical layer, EN 301 842-2 [5] deals with core link layer functionality and EN 301 842-3 [6] with additional broadcast functionality. The present document deals with tests of the datalink service (DLS) layer and the link layer sufficient to support point-to-point functionality. Note that, as described in EN 301 842-2 [5], a system supporting point-to-point functionality is required to conform to EN 301 489-22 [2], EN 301 842-1 [4], EN 301 842-2 [5] and the specification in the present document. The present document is organized as follows:
- clause 2 provides references to relevant documents;
- clause 3 provides general definitions, abbreviations and symbols used;
- clause 4 describes the VDL Mode 4 ground station point-to-point functions;
- clause 5 provides performance specifications for the VDL Mode 4 ground station;
- clause 6 provides general design requirements;
- clause 7 provides protocol tests for the point-to-point functions of the system;
- annex A provides a detailed cross-reference to the relevant requirements contained in [1];
- annex B provides a Bibliography;
- a document history.
Note that the system can support a very wide range of functions. It is not practical to provide specific tests for all aspects of functionality. The approach used is to provide detailed tests for the core point-to-point functionality and to provide tests of those remaining requirements which, if wrongly implemented, could cause a deterioration in the service offered by other VDL Mode 4 stations.
Mandating and Recommendation Phrases
a) "Shall":
- the use of the word "Shall" indicates a mandated criterion; i.e. compliance with the particular procedure or specification is mandatory and no alternative may be applied.
b) "Should":
- the use of the word "Should" (and phrases such as "It is recommended that...", etc.) indicates that though the procedure or criterion is regarded as the preferred option, alternative procedures, specifications or criteria may be applied, provided that the manufacturer, installer or tester can provide information or data to adequately support and justify the alternative.
Radijska oprema za VHF digitalne povezave zrak-tla, 4. način - Tehnične karakteristike in merilne metode za talno opremo - 4. del: Funkcije za sistem točka-točka
Pričujoči dokument velja za naslednje tipe radijske opreme:
1) zelo visokofrekvenčna (VHF) digitalna povezava (VDL), 4. način, talnih radijskih oddajnikov in prejemnikov za komunikacije zrak-tla, ki deluje v pasu VHF z uporabo modulacije frekvenčnega premičnega kodiranja prek filtra Gaussian (GFSK) z razmikom 25 kHz med kanali in zmožna uravnavanja na kateri koli izmed kanal 25 kHz od 118.000 MHz do 136.975 MHz, kot je opredeljeno v standardih in priporočenih praksah (SARPs) [8] ICAO za digitalne povezave VHF (VDL). Pričujoči dokument zagotavlja 4. del tehničnih specifikacij. Pričujoči dokument zagotavlja, da bo po oprema, ki jo certificira, združljiva z ustreznimi standardi in priporočenimi praksami (SARPs) [8] ICAO za digitalne povezave VHF (VDL) ter tehničnim priročnikom (TM) [1] za VDL, 4. način. Proizvajalci morajo biti pozorni, da razpon uravnavanja za talne prejemnike - oddajnike lahko v prihodnje zajema tudi kateri koli kanal 25 kHz od 108.000 MHz do 117.975 MHz. Področje uporabe pričujočega dokumenta je omejeno na talne postaje. Ustrezna specifikacija za letalske postaje je v EN 302 842 [7]. Opis področja uporabe sistemov VDL, 4. način, je naveden v 2. delu teh tehničnih specifikacij (glej EN 301 842-2 [5], klavzulo 1). EN 301 842-1 [4] obravnava preskuse fizične plasti, EN 301 842-2 [5] obravnava funkcionalnost plasti jedrne povezave in EN 301 842-3 [6] dodatno funkcionalnost oddajanja. Pričujoči dokument obravnava preskuse plasti storitve podatkovne povezave (DLS) ter plasti povezave, ki zadostuje za podporo funkcionalnosti točka-točka. Bodite pozorni, da je, kot je opisano v EN 301 842-2 [5], sistem, ki podpira funkcionalnost točka-točka, potreben za skladnost z EN 301 489-22 [2], EN 301 842-1 [4], EN 301 842-2 [5] in specifikacijo v pričujočem dokumentu. Pričujoči dokument je urejen:
- klavzula 2, ki se sklicuje na ustrezne dokumente;
- klavzula 3, ki podaja uporabljene splošne definicije, okrajšave in simbole;
- klavzula 4, ki opisuje funkcije VDL zemeljskih postaj točka-točka, 4. način;
- klavzula 5, ki podaja specifikacije za zmogljivost za VDL zemeljskih postaj, 4. način;
- klavzula 6, ki podaja splošne zahteve za načrtovanje;
- klavzula 7, ki podaja preskuse protokola za funkcije točka-točka sistema;
- dodatek A, ki podaja podrobno sklicevanje na ustrezne zahteve, zajete v [1];
- dodatek B, ki podaja bibliografijo;
- zgodovina dokumenta.
Bodite pozorni na to, da lahko sistem podpira zelo širok razpon funkcij. Podajanje določenih preskusov za vse vidike funkcionalnosti ni praktično. Namen uporabljenega pristopa je podati podrobne preskuse za jedrno funkcionalnost točka-točka in zagotoviti preskuse tistih preostalih zahtev, ki pod pogojem, da se narobe izvajajo, lahko povzročijo poslabšanje storitev, ki jih ponujajo postaje VDL, 4. način.
Fraze, ki zahtevajo in ki priporočajo
a) »Mora«:
- uporaba besede »mora« nakazuje obvezni kriterij; npr. skladnost z določenim postopkom ali specifikacijo je obvezna in nobena druga možnost se ne sme uporabiti.
b) »Naj«:
Uporaba besede »naj« (in fraze, kot je »Priporoča se, da …« itd.) nakazuje, da čeprav se postopek ali merilo šteje za prednostno možnost, se lahko uporabijo drugi postopki, specifikacije ali merila, pod pogojem, da proizvajalec, monter ali preizkuševalec lahko zagotovijo informacije ali podatke, s katerimi ustrezno podprejo in upravičijo drugo možnost.

Introduction
The present document is part of a multi-part deliverable developed by ETSI and is designed to fit in a modular structure
to cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive [i.1]. The
modular structure is shown in EG 201 399 [i.2].
The present document states the technical specifications for Very High Frequency (VHF) Digital Link (VDL) Mode 4
ground-based radio transmitters, transceivers and receivers for air-ground communications operating in the VHF band,
using Gaussian-filtered Frequency Shift Keying (GFSK) Modulation with 25 kHz channel spacing and capable of
tuning to any of the 25 kHz channels from 118,000 MHz to 136,975 MHz as defined in ICAO VHF Digital Link (VDL)
Standards and Recommended Practices (SARPs) [8].
The present document may be used to produce tests for the assessment of the performance of the equipment. The
performance of the equipment submitted for type testing should be representative of the performance of the
corresponding production model.
The present document has been written on the assumption that:
• the type test measurements will be performed only once, in an accredited test laboratory and the measurements
accepted by the various authorities in order to grant type approval;
• if equipment available on the market is required to be checked it will be tested in accordance with the methods
of measurement specified in the present document or a documented alternative approved by the certifying
authority;
• equipment comply with EN 301 489-22 [2], EN 301 842-1 [4] and EN 301 842-2 [5].
