15、 55 Page 7 ETS 300 722: June 1997 1 Scope This European Telecommunication Standard (ETS) provides specifications for the standardization of the characteristics of the minimum required Network Control Facilities (NFCs) for Mobile Earth Stations (MESs) with both transmit and receive capabilities in or
16、der to ensure that the network operator is able to suppress and enable the transmissions from the MESs. These facilities will insure that certain interference situations, resulting from the emissions from interfering or faulty M ESs, will be terminated; in particular for the protection of the radio
17、astronomy services. This ETS defines specifications for the control facilities in a satellite network in which MESs as defined in ETS 300 721 l operate. This ETS deals with specifications, defined in order to protect other users of the frequency spectrum from unacceptable interference. 2 Normative r
18、eference This ETS incorporates by dated and undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publica
19、tions apply to this ETC only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. ETS 300 721: “Satellite Earth Stations and Systems (SES); MES providing Low Bit Rate Data Communications (LBRDC) using LEO satellites opera
20、ting below 1 GHz“. 3 Abbreviations For the purposes of this ETS, the following abbreviations apply: MES NCF Mobile Earth Station Network Control Facility 4 Testreport The test report shall contain the results of the test. 5 Suppression of MES transmissions Purpose: To inhibit the transmissions from
21、any MES when found necessary, with the NCFs. Specification: By entering an appropriate command, said “inhibition command“ at the NCF, it shall be possible to send a transmission disabled command to any MES in the network, in order to suppress its transmissions and to inhibit any further transmission
22、s until a transmission enabled command is received. Verif cation: By documentary evidence and demonstration. Verification of transmission suppression shall be performed after commanding inhibition. STD-DIN DIN ETS 300722-GERM 1978 m 277q44b 0728485 771 m Page 8 ETS 300 722: June 1997 6 Enabling of M
23、ES transmissions Purpose: To re-enable transmissions from an MES or several MESS whose transmissions have previously been suppressed.
