This TBR specifies those technical requirements under Articles 4.1 to 4.5 of Council Directive 93/97/EEC that apply to satellite earth station equipment that is capable of operation in one or more of the following frequency ranges: - 10,70 to 11,70 GHz (Space - Earth, shared) - 12,50 to 12,75 GHz (Space - Earth, exclusive) - 14,00 to 14,25 GHz (Earth - Space, exclusive) of the Fixed Satellite Service (FSS). These requirements are taken from ETS 300 255. This TBR does not contain the essential requirements under Article 4.6 for interworking via the public telecommunications network in justified cases, and does not provide any guarantee of correct interworking between satellite earth station equipment. This TBR specifies the requirements for satellite earth station equipment that - is capable of being used either for transmission only, or for transmission and reception (transmit-receive), or for reception only (receive-only), of radio-communication signals in any of the bands specified above; - is not within the scope of other Ku-band TBRs (TVRO, VSAT, SNG); - is not purpose built satellite earth sation equipment intended for use as part of the public telecommunications network. This TBR applies to all satellite equipment as described above, irrespective of whether the satellite earth station equipment provides additional interfaces, telecommunications services or functions. However additional TBRs may also apply.
