"SonetSpec_GR253.pdf" 本文档是关于Synchronous Optical Network (SONET) Transport Systems的通用规范，具体为Telcordia GR-253-CORE的第四版，发布于2005年12月。GR-253是电信行业的一个重要标准，它定义了同步光网络（SONET）传输系统的一般通用要求。此文档是TSGR、FR-440、FR-SONET-17和FD-29系列的一部分，用于指导和规范电信网络中的SONET设备和系统的操作。 SONET是一种在长途通信中广泛使用的数字传输体系结构，它为同步数据传输提供了标准化的框架。此技术最初由美国电信工业协会（TIA）和电气电子工程师协会（IEEE）开发，旨在改善北美地区的电话网络。SONET网络能够承载各种类型的信号，包括语音、数据和视频，并通过多个速率级别提供同步服务。 GR-253-CORE文档的主要目的是设定SONET传输系统的通用标准，确保设备间的互操作性和网络的可靠性。这些标准涵盖了硬件设计、环境耐受性、性能监控、故障检测和恢复机制等方面。文档的第四版取代了第三版，并且在内容上有添加、修改或删除的部分，这些变化在页面外侧的垂直条纹标记处可以找到。文档的使用者可以通过联系公司文档协调员、Telcordia的账户经理，或者拨打1.866.672.6997（美国）或+1.732.699.6700（全球）获取更多信息或复制此文档。此外，也可以访问Telcordia的官方网站http://telecom-info.telcordia.com来获取电子版。版权信息显示，此文档的知识产权归1995年至2000年，2005年的Telcordia Technologies, Inc.所有。文档中还提到了一些商标，如“Telcordia”是Telcordia Technologies, Inc.的注册商标，而“NEBS”和“CLEI”也是该公司的商标。 GR-253-CORE提供了SONET传输系统的详细设计和操作指南，对于理解、建设和维护SONET网络的工程师和电信专业人员来说，这是一个必不可少的参考资料。这份文档不仅规定了设备的物理层要求，还包括了网络管理和维护的高级特性，以确保高效、稳定和安全的通信服务。
