本文件规定了欧洲公共电信运营商通过数字用户信令系统1号（DSS1）协议提供的泛欧综合业务数字网（ISDN）的T参考点或重合S和T参考点网络侧的测试套件结构和测试目的（TSS&TP），用于网络集成测试（NIT），涵盖ISDN服务的端到端支持。泛欧ISDN通过连接不同的国家网络构成，端到端NIT涵盖了从接入接口、网络侧的角度接入互联网络的正确行为所需的所有测试活动。在pan中检查承载业务（以及相关的电信业务）和补充业务的互通能力和兼容性- 欧洲ISDN。

This document specifies the Test suite structure and test purposes (TSS&TP) for the network side of the T reference point or coincident S and T reference point for the pan-European Integrated Services Digital Network (ISDN) as provided by European public telecomunications operators by means of the Digital subscriber Signalling System No. one (DSS1) protocol, for Network Integration Testing (NIT) covering the end-to-end support of ISDN services. The pan-European ISDN is made up by connecting the different national networks and End-to-end NIT covers all the testing activities necessary to access the correct behaviour of the interconnected network from the point of view of access interfaces, network side. Both bearer services (and associated teleservices) and supplementary services are checked for interworking capability and compatibility, in the pan-European ISDN.
