本TBR规定了能够连接到GSM网络（PLMN）并使用DECT进行网络接入的终端设备应提供的技术特性。这种终端设备的无绳传输在1880-1900 MHz的频段内工作。DECT终端设备包括两个部件，分别称为固定部件（FP）和便携式部件（PP）。本TBR的目标是确保FP和PP之间的空中接口互操作性符合DECT/GSM互通配置文件IWP（注2），其中这些部件能够实现3.1 kHz的电话应用，并且FP连接到GSM PLMN，以便通过DECT空中网络提供GSM服务（根据TBR 19/20）- 界面对于FP的功能部件，即终端设备，其声明符合DECT的基本CTR（注1）和DECT/GSM IWP，除适用于相应GSM PLMN的附件要求外，本TBR的要求也应适用。本TBR的要求也适用于声明符合DECT/GSM IWP的PP的整套功能。对于PP，本TBR是DECT基本CTR的补充。如果某项功能被指定为可选功能，则无需提供该功能。 但如果提供了此类功能，FP和/或PP应符合本TBR的要求和测试。本TBR的结构允许FP和PP作为单独项目进行型式认证。对于本TBR中的每项要求，均给出了试验，包括适用的测量方法。必要时，可通过附加设备刺激终端设备进行试验。本TBR不适用于构成GSM PLMN一部分的FPs。注1:基本CTR fordDECT是一般附件要求（CTR 6）、电话应用要求（CTR 10）和通用访问配置文件要求（CTR 22）。 注2:关于本TBR，DECT/GSM IWP基于ETS 300 370的接入映射/互通要求，以及prETS 300 466的服务、能力和信息流的一般说明。

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.
