标准摘要
[中文适用范围]： 指定混合光纤同轴电缆 (HFC) 外部设备 (OSP) 媒体访问控制 (MAC) 层的要求。该标准是为支持不断发展的 HFC 电缆的可互操作管理系统的设计和实施而开发的系列的一部分 [外文原描述]： specifies requirements for The Hybrid Fibre Coax (HFC) Outside Plant (OSP) Media Access Control (MAC) Layer. This standard is part of the series developed to support the design and implementation of interoperable management systems for evolving HFC cable networks. The HMS Media Access Control (MAC) layer specification describes the messaging and protocols implemented at the Data Link Layer (DLL), layer 2 in the 7 layer ISO-OSI reference model, that support reliable and efficient communications between HMS compliant transponders interfacing to managed OSP network elements (NEs) and a centralized head-end element (HE).
