标准摘要
[中文适用范围]： 规定了混合光纤同轴电缆 (HFC) 室外 (OSP) 电源 (PS) 的要求。该标准是为支持不断发展的 HFC 有线网络的可互操作管理系统的设计和实施而开发的系列标准的一部分。这 [外文原描述]： specifies requirements for the Hybrid Fibre Coax (HFC) Outside Plant (OSP) Power Supplies (PS). This standard is part of a series developed to support the design and implementation of interoperable management systems for evolving HFC cable networks. The purpose of the standards is to support the design and implementation of interoperable management systems for evolving HFC cable networks. The Power Supply to Transponder Interface Bus (PSTIB) specification describes the physical (PHY) interface and related messaging and protocols implemented at the Data Link Layer (DLL), layers 1 and 2 respectively in the 7-layer ISO-OSI reference model, that support communications between compliant transponders and the managed OSP power supplies and other related power equipment to which they interface.
