¿µ¹®³»¿ë¿ä¾à | The standard provides the definitions, terminology and abbreviations used in ITU T Recommendations on timing and synchronization in packet networks. It includes mathematical definitions for various synchronization stability and quality metrics for packet networks, and also provides background information on the nature of packet timing systems and the impairments created by packet networks. Ethernet physical layer methods for synchronization are based on traditional time division multiplexing (TDM) physical layer synchronization and therefore most of the definitions related to these methods are covered by [ITU T G.810]. Additional definitions are included in the Recommendation. The amendment standard provides the following updates:
- Modification to reference [IEEE 1588] in clause 2. - Modified and added some definitions in clause 3. - Modification to some contents in clause ¥°.4.4.3. |
