This TBR specifies the technical characteristics to be provided by terminal equipment which is capable of connecting to a GSM network (PLMN) and which uses DECT for network access. The cordless transmission for such terminal equipment operates within the frequency band 1880 - 1900 MHz. A DECT-terminal equipment comprises two elements, referred to as a Fixed Part (FP) and a Portable Part (PP). The objective of this TBR is to ensure air-interface interoperability beteween a FP and a PP following the DECT/GSM interworking profile IWP (Note 2), where these parts are capable of 3,1 kHz telephony applications, and where the FP is connected to the GSM PLMN in order to provide GSM services (according to TBR 19/20) over the DECT air-interface. For functional parts of a FP, that are terminal equipment, which are declared to conform to the basic CTRs for DECT (Note 1) and to the DECT/GSM IWP, the requirements of this TBR shall apply, in addition to the attachment requirements for the appropriate GSM PLMN. The requirements of this TBR are also applicable for the complete set of functionality of a PP declared to conform to the DECT/GSM IWP. For a PP, this TBR is in addition to the basic CTRs for DECT. Where a feature is indicated as optional, it need not to be provided. But where such a feature is provided, the FP and/or PP shall conform to the requirements and tests of this TBR. This TBR is structured to allow type approval of the FP and PP as separate items. For each requirement in this TBR, a test is given, including measurement methods where applicable. The terminal equipment may be stimulated to perform the tests by additional equipment if necessary. This TBR does not apply to FPs where they form part of the GSM PLMN. Note 1: The basic CTR fordDECT are the general attachment requirements (CTR 6), requirements for telephony applications (CTR 10) and requirements for Generic Access Profile (CTR 22). Note 2: With respect to this TBR, the DECT/GSM IWP is based on the provision of access mappings/ interworking requirements of ETS 300 370 and the general description of of services, capabilities and information flows of prETS 300 466.
