ETSI TS 103 158包含“新”的概要测试规范（PTS）和测试用例库（TCL） DECT一代；第4部分“数字增强无绳通信（DECT）.新一代DECT.第4部分: 光数据服务；“无线软件更新（SUOTA）、内容下载和基于HTTP的应用程序”本文档涵盖了便携式（PT）和固定式（FT）无线电终端。测试用例库（TCL）还涵盖了“DECT数字分组无线电服务”[i.4]的一些测试用例。这一点已经完成 因为此类测试用例是强制性的，或者与新一代DECT第4部分特别相关 （见ETSI TS 102 527-4[5]）。本文件的目的是为NG的认证测试提供依据- DECT第4部分[5]设备 不同制造商DECT设备之间的空中接口互操作性的高概率。

ETSI TS 103 158 contains the Profile Test Specification (PTS) and the Test Case Library (TCL) for "New Generation DECT; Part 4"Digital Enhanced Cordless Telecommunications (DECT); New Generation DECT; Part 4: Light Data Services; Software Update Over The Air (SUOTA), content downloading and HTTP based applications"The present document covers both the Portable (PT) and the Fixed (FT) Radio terminations.The Test Case Library (TCL) covers also some test cases for "DECT Digital Packet Radio Service" [i.4]. This is done because such test cases are mandatory or especially relevant for New Generation DECT Part 4 (see ETSI TS 102 527-4 [5]).The objective of the present document is to provide a basis for approval tests of NG-DECT Part 4 [5] equipment giving a high probability of air interface inter-operability between different manufacturer's DECT equipment.
