本TBR规定了指令91/263/EEC第4（g）条项下的技术特征（电气和声学要求），该技术特征将由单个手持电话终端设备提供，该终端设备旨在:（a）获得泛欧认证；和（b）通过双线连接到PSTN的模拟接口。该接口的特点是一个直流环路，用于指示捕捉和清除，低频交流振铃信号低于语音通带，用于指示传入呼叫，在传输阶段，网络终端点的带宽约为3 kHz； 以及（c）支持语音电话案例服务。北电、英国电信、西门子、CSELT、BAKOM/OFCOM、GPT支持的工作项目

This TBR specifies the technical characteristics (electrical and acoustic requirements) under Article 4(g) of Directive 91/263/EEC to be provided by a single, handset telephony, terminal equipment which is intended: (a) for pan-European approval; and (b) for connection by 2-wires to an analogue interface of a PSTN. This interface is characterised by a d.c. loop to indicate seizure and clearing, low frequency a.c.ringing signals below the speech passband to indicate an incoming call and in the transmission phase has an approximate bandwidth of 3 kHz at the network termination point; and (c) for supporting the voice telephony justified case service.
