本文件规定了网络运营商在向服务提供商提供特殊访问时的要求，主要是在网络完整性领域（但不一定限于）。本工作项遵循DEG/NA-061601，采用等效范围（仅限增强型电话服务）。服务交互和对其他类型网络的应用将在后续工作项中考虑。参考文件:NA-061209、NA-061208、NA-061205、NA-061204、NA-061601、关于特殊网络访问的ECTRA报告、关于网络完整性的ECTRA报告、关于CLI的ETP报告。

This document specifies the requirements that network operators have in delivering special accesses to service providers, mainly in the field of (but not necessarily restricted to) network integrity. This work item follows on from DEG/NA-061601, adopting an equivalent scope (enhanced telephony services only). Service interaction and application to other types of network will be considered in a subsequent work item.
