Scope

YD/T 1179-2002 is the English-translated version of 在同步数字体系(SDH)上传送以太网帧的技术规范.

YD/T 1179-2002 is the Chinese standard "Technical Specification of Ethernet over SDH". This standard specifies the Ethernet frame (defined by the working group IEEE802.

3) over SDH protocol stack, which can be used for synchronous digital hierarchy (ITU-T G. 707 standard). ITU-T X. 85/Y. 1321 introduced LAPS protocol standard and norms continue to be used for the Ethernet adapter to provide LAPS.

Describes a similar HOLC LAPS framing structure used to package IEEE 802. 3 Ethernet MAC frame, which provides a point to point full duplex operation. LAPS, Ethernet and SDH physical layer as well as the relationship between the rate adaptation layer shown in Figure l, in the coordination of sub- layer has the flow control function.

This standard does not specify the specific LAPS to SDH mapping method for all Ethernet-based protocols (including IEEE 802. 3 Ethernet) and all the SDH standard without any alteration. Issued on 2002-02-01, in force from 2002-02-01.

1 Foreword

YD/T 1179-2002 was issued by Ministry of Industry and Information Technology on 1 February 2002 and took effect the same day.

The YD/T prefix marks a recommended standard. It is not law in itself: it becomes binding when a contract names it, when a regulation or a mandatory standard refers to it, or when a producer declares conformity with it.

The document runs to 9 pages in English translation.

This standard specifies the Ethernet frame (defined by the working group IEEE802. 3) over SDH protocol stack, which can be used for synchronous digital hierarchy (ITU-T G. 707 standard). ITU-T X. 85/Y. 1321 introduced LAPS protocol standard and norms continue to be used for the Ethernet adapter to provide LAPS. Describes a similar HOLC LAPS framing structure used to package IEEE 802. 3 Ethernet MAC frame, which provides a point to point full duplex operation. LAPS, Ethernet and SDH physical layer as well as the relationship between the rate adaptation layer shown in Figure l, in the coordination of sub- layer has the flow control function. This standard does not specify the specific LAPS to SDH mapping method for all Ethernet-based protocols (including IEEE 802. 3 Ethernet) and all the SDH standard without any alteration.

YD/T 1179-2002 is filed under Chinese Standard Classification L79, in the field of electronic components and information technology.
