（暂定）数据终端设备（DTE）连接到基于ITU-TV系列建议的物理和电气网络演示文稿的连接要求。本TBR将结合并协调TBR 1和TBR 2的要求。TBR将包含指令91/263/EEC下认为必要的所有要求，以批准此类终端，无论通过此类接口传输的协议如何。特别是，TBR将包含连接到V.10、V.11、V.12、V.28、V.35和V.36网络演示文稿的要求，并将取代TBR 1和TBR 2。参考文件:TBR 1、TBR 2、ITU- t建议五.10、五.11、五.12、五.28、五.35和五.36

(Provisional) Attachment requirements for Data Terminal Equipment (DTE) to connect to physical and electrical network presentations that are based upon the ITU-T V Series of Recommendations. This TBR will combine and harmonize the requirements of TBR 1 and TBR 2. The TBR will contain all requirements deemed essential under Directive 91/263/EEC to approve terminals within this category regardless of the protocols transported accross such interfaces. In particular, the TBR will contain requirements for connection to V.10, V.11, V.12, V.28, V.35, and V.36 network presentations and will supercede TBR 1 and TBR 2.
